Rh In the temperate parts of the Old World this species is perhaps the most abundant of the plovers, Charadriidae, breeding in almost every suitable place from Ireland to Japan—the majority migrating towards winter to southern countries, as the Punjab, Egypt and Barbary—though in the British Islands some are always found at that season. As a straggler it has occurred within the Arctic Circle (as on the Varanger Fjord in Norway), as well as in Iceland and even Greenland; while it not unfrequently appears in Madeira and the Azores. Conspicuous as the strongly contrasted colours of its plumage and its very peculiar flight make it, it is remarkable that it maintains its ground when so many of its allies have been almost exterminated, for the lapwing is the object perhaps of greater persecution than any other European bird that is not a plunderer. Its eggs are the well-known “plovers’ eggs” of commerce, and the bird, wary and wild at other times of the year, in the breeding-season becomes easily approachable, and is shot to be sold in the markets for “golden plover.” Its growing scarcity in Great Britain was very perceptible until the various acts for the protection of wild birds were passed. It is now abundant and is of service both for the market and to agriculture. What seems to be the secret of the lapwing holding its position is the adaptability of its nature to various kinds of localities. It will find sustenance equally on the driest of soils as on the fattest pastures; upland and fen, arable and moorland, are alike to it, provided only the ground be open enough. The wailing cry and the frantic gestures of the cock bird in the breeding-season will tell any passer-by that a nest or brood is near; but, unless he knows how to look for it, nothing save mere chance will enable him to find it. The nest is a slight hollow in the ground, wonderfully inconspicuous even when deepened, as is usually the case, by incubation, and the black-spotted olive eggs (four in number) are almost invisible to the careless or untrained eye. The young when first hatched are clothed with mottled down, so as closely to resemble a stone, and to be overlooked as they squat motionless on the approach of danger. At a distance the plumage of the adult appears to be white and black in about equal proportions, the latter predominating above; but on closer examination nearly all the seeming black is found to be a bottle-green gleaming with purple and copper; the tail-coverts, both above and below, are of a bright bay colour, seldom visible in flight. The crest consists of six or eight narrow and elongated feathers, turned slightly upwards at the end, and is usually carried in a horizontal position, extending in the cock beyond the middle of the back; but it is capable of being erected so as to become nearly vertical. Frequenting parts of the open country so very divergent in character, and as remarkable for the peculiarity of its flight as for that of its cry, the lapwing is far more often observed in nearly all parts of the British Islands than any other of the group Limicolae. The peculiarity of its flight seems due to the wide and rounded wings it possesses, the steady and ordinarily somewhat slow flapping of which impels the body at each stroke with a manifest though easy jerk. Yet on occasion, as when performing its migrations, or even its almost daily transits from one feeding-ground to another, and still more when being pursued by a falcon, the speed with which it moves through the air is very considerable. On the ground this bird runs nimbly, and is nearly always engaged in searching for its food, which is wholly animal.

Allied to the lapwing are several forms that have been placed by ornithologists in the genera Hoplopterus, Chettusia, Lobivanellus, Defilippia. In some of them the hind toe, which has already ceased to have any function in the lapwing, is wholly wanting. In others the wings are armed with a tubercle or even a sharp spur on the carpus. Few have any occipital crest, but several have the face ornamented by the outgrowth of a fleshy lobe or lobes. With the exception of North America, they are found in most parts of the world, but perhaps the greater number in Africa. Europe has three species—Hoplopterus spinosus, the spur-winged plover, and Chettusia gregaria and C. leucura; but the first and last are only stragglers from Africa and Asia.

 LAPWORTH, CHARLES (1842– &emsp;&emsp; ), English geologist, was born at Faringdon in Berkshire on the 30th of September 1842. He was educated partly in the village of Buckland in the same county, and afterwards in the training college at Culham, near Oxford (1862–1864). He was then appointed master in a school connected with the Episcopal church at Galashiels, where he remained eleven years. Geology came to absorb all his leisure time, and he commenced to investigate the Silurian rocks of the Southern Uplands, and to study the graptolites and other fossils which mark horizons in the great series of Lower Palaeozoic rocks. His first paper on the Lower Silurian rocks of Galashiels was published in 1870, and from that date onwards he continued to enrich our knowledge of the southern uplands of Scotland until the publication by the Geological Society of his masterly papers on The Moffat Series (1878) and The Girvan Succession (1882). Meanwhile in 1875 he became an assistant master in the Madras College, St Andrews, and in 1881 professor of geology and mineralogy (afterwards geology and physiography) in the Mason College, now University of Birmingham. In 1882 he started work in the Durness-Eriboll district of the Scottish Highlands, and made out the true succession of the rocks, and interpreted the complicated structure which had baffled most of the previous observers. His results were published in “The Secret of the Highlands” (Geol. Mag., 1883). His subsequent work includes papers on the Cambrian rocks of Nuneaton and the Ordovician rocks of Shropshire. The term Ordovician was introduced by him in 1879 for the strata between the base of the Lower Llandovery formation and that of the Lower Arenig; and it was intended to settle the confusion arising from the use by some writers of Lower Silurian and by others of Upper Cambrian for the same set of rocks. The term Ordovician is now generally adopted. Professor Lapworth was elected F.R.S. in 1888, he received a royal medal in 1891, and was awarded the Wollaston medal by the Geological Society in 1899. He was president of the Geological Society, 1902–1904. His Intermediate Text-book of Geology was published in 1899.

LAR, a city of Persia, capital of Laristan, in 27° 30′ N., 53° 58′ E., 180 m. from Shiraz and 75 from the coast at Bander Lingah. It stands at the foot of a mountain range in an extensive plain covered with palm trees, and was once a flourishing place, but a large portion is in ruins, and the population which early in the 18th century numbered 50,000 is reduced to 8000. There are still some good buildings, of which the most prominent are the old bazaar consisting of four arcades each 180 ft. long, 14 broad and 22 high, radiating from a domed centre 30 ft. high, an old stone mosque and many cisterns. The crest of a steep limestone hill immediately behind the town and rising 150 ft. above the plain is crowned by the ruins of a castle formerly deemed impregnable. Just below the castle is a well sunk 200 ft. in the
