 A HISTORY OF KENT to be new named it D. westwoodii. In this genus the first antennae are twenty-five jointed, the right one in the male being prehensile. Eurytemora affinis (Poppe) and £. lac'wulata (Fischer) have been found by Scourfield at Gravesend. The first antennae are twenty-four jointed, with the clasper on the right. Of the family Arpacticidae Canthocampus staphylinus (Jurine) is reported by Scourfield from Chislehurst, and Moraria ajidersonsmithi, T. and A. Scott, from Keston. The last-named authors say that the genus Moraria was instituted to include an interest- ing Arpactid from Loch Morar, Inverness-shire, ' having characters connecting the fresh-water species Attheyella cryptorum, Brady, with the marine Cylindropsyllus laevis, Brady.' ' ' The anterior antennae in both male and female are short, stout, and seven-jointed, the male antennae being hinged between the fourth and fifth joints, and adapted for grasping.'^ Mr. Scourfield, writing to me, 17 May 1902, says, 'I also enclose a summary of all my records of fresh and brackish water Entomostraca from Kent. I am sorry it is not longer, but it has happened that I have not collected much in Kent. There are, however, several interesting things in the list, e.g. the two species of 'Eurytemora, Cyclops dybowskii, and Moraria andersonsfiiithi.^ It can scarcely be neces- sary to point out how largely Mr. Scourfield, by his generous supply of unpublished lists, has contributed to the completeness of this report on the Crustacea of the county. Of parasitic and semiparasitic Entomostraca many are Copepoda which attach themselves with more or less freedom or fixity to fishes, and are on that account called ' fish-lice.' How large a number of parasitic Crustacea in general might be added to the catalogue of the Kentish fauna can be with certainty inferred from some passages in England's Topographer, in which their hosts are mentioned. Thus Mr. Ireland says, ' The Medway abounds in fish ; particularly carp, perch, tench, pike, dace, chub, roach, and gudgeons ; and but rarely a salmon is caught weighing twelve or fourteen pounds : that fish formerly abounded in this river,i as several manors belonging to the priory of Rochester were compelled to furnish one or more annually, for the table of the monks : and below Rochester, the finest and largest smelts are caught, as well as soals, flounders, dabs, thornbacks, maids, etc. In former times the sturgeon was so abundant in the stream that the Bishop of Rochester claimed a duty from the same, which constituted a con- siderable part of his revenue, as second to the Archbishop ; another being also paid to the King.' 'The Cray abounds in trout of the finest flavour, colour and size.' Elsewhere he tells us that ' In the year 1774 a most remarkable fish was caught on Faversham Flats, called mola salviani, or the sun fish, which weighed about nineteen pounds and a half, and was two feet in diameter. This fish is very rarely met with in our narrow seas,' and in a ' Chronology of remarkable events relating to Maidstone,' one entry is, ' R. whale and two porpusses taken in > Annals and Magazine of Natural History, ser. 6, xi. 213 (1893). » T.
