Its vexillum is remarkably long, and of the fhapc of a fword ; its aire and carina inert ; from the cup of the flower there arifes a cylindric piftil, furrounded by a fimbriated membrane, which finally becomes a fort of knotty pod, cqmpofed of two Valves, and containing a number of kidney-fhaped feeds. The fpecies of corallodendron enumerated by Mr. Tourne- fort, are thefe; i. The prickly, trifoliate, American comlto- ■der.dron, with bright red flowers. 2. The fmallcr, American trifoliate corallodendron, with black fpines, and black feeds. 3. The afh-Icavcd, American corallodendron. 4.

Coralloides is alfo ufed in a different fenfe. Bauhinc and Chabra^us have made it the name of the great dentaria hepta- pbyilos; and Dillenius, that of a whole genus of the dry leaf- Jefs mofles. Dale, Pharm. p. 200. SeeFlEATH-ma/j.

CORAX pifds* the croiu-Jyh^ in zoology, the name of a fifh of the cuculus kind, and much approaching to the fwallow fifh in. fhape and figure. The bones which cover the gills in this fifh, all terminate in fharp thorns. The gill-fins are fmallcr than in the fwallow-fifh, and are white on the outfide, and of

, ablackifh green within. The back is of a bluifh black ; the fides reddifh, and the belly milk white. The head is very large j and there are two rows of pointed bony fubffances on the back. The forehead, between the eyes, is marked with fevcral figures ; and the mouth is of a pale yellow, much lefs coloured than that of the milvus. Gejncr, dc Pifc. p 356. See Milvus pi/cis.

CORBE1L, in natural hiflory, the name of a curious fpecies of chama. It is of the larger kind, and is deeply filiated, both longitudinally and tranfverfely; fo that it has a fort of reticu- lated furface, like bafket-work. See Chama.

CORCELET, in natural hiflory, th3t part of the fly clafs which is analogous in its fituation to the breafl: in other animals. Many have called it the brcaft in thefe alfo, but improperly ; becaufcthe breait of other animals is the place of the limtrs and trachea ; but thefe organs are in the fly clafs diftributed thro' the whole body. The wincjs are affixed to this part of the fly clafs ; and there are fome did Mictions of great confe- querve, in regard to the arrangement and diilribution of thofc animals into genera. Reeumur\ Hift. Infect. T. 4. p. 1 26. Some flics have a double corcelet, or one divided into two parts ; and this is the cafe of the fly produced from the formica-leoj which therefore does not carry its only diftindtion in the figure Sf its antenna?. One pair of the legs of this fly are attached to the ru-ft or anterior corcelet, which is alfo capable of mov- ing on the other.

The wcelets of fome flies is much more elevated alfo than thofe of others ; and in fome this elevation is carried fo far,

COR

that the head is forced by it to be bent downward, and the creature is plainly made hump-backed by it. The great kind, and the tipulu, furnifh inftances' of this elevated and humped torcilet.

A feries of flies of two wings, are known by a very particular armament which they carry on the amid, ufually called their breafl. This is two long, (lender, and fharp pointed prickles, which are immoveable in their infertions, and fcem meant as defenfivc or offenfive weapons ; but in what manner they arc ufed, is not eafily to be determined.

All thefe flies are produced from long water- worms, with open and funncl-fafhioned tails, orfurnifhed with their aperture for refpiration at the hinder extremity. Tlefe tails are bordered with hairs, which the creature makes to diverge from their in- fertion, and form a fort of funnel at the furface of the water, when it throws Up its tail for air.

There are three known fpecies of this fort of fly, with armed arcelets, which differ much in fize, but are all produced of worms of this kind. The Iargefr. of thefe flies is produced from the largeft and longeft Worm, and arc fomething longer than the bee. The fmalleft are produced of worms very fmall and (lender, and are themfelves extremely minute : and the third kind is of a middle fize between thefe, and produced of a proportionably fmallcr worm than that of the firfl, and pro- portionably larger than that of the Iccond fpecies. All thefe fpecies have their wings but little diftinguifhable at their firft production from the fhell ; they appear, indeed; only like two (lender filaments, laid along their bodies, but they foon (hew, that in this (late they were only very nicely folded to- gether, and very foon expand, and drew their full extent and proportion.

When firft producced from the (hell, thefe flies are of a pale green, and the under part of their belly, in many, continues green, but in the greater number it becomes of a pale dead brown. Some of them have the outfide of their bodies of a deep brown, approaching to black, with lines Of a dead brown between the commiffuies of the rings. The back of fome others has only a blackilh brown band, which runs (trait down, from the ccrcelet to the end of the body, the whole body befide being of a dead brown. The orcein in thefe flies is brown, and the prickles are yellowifh near their infertions, but, neatly black at their points. They have three of the fmall gloil'y e; es, dilpofcd in figure of a triangle on the back part of their head ; and their reticular eyes arc brown, and at fome diftance from one another. Reaumur, Hift.

CORDIA, in botany, the name by which Linmeus and PIu- mier have called a genus Sf plants, cs\Wi febe/1 er,a by Dillenius in his Hortus elthamenfis. The charaaers are thefe : the cup is a one-leav'd perianthium, divided into three pointed fer- ments, from a tubular bafe, and remai/iing after the flower Is fallen. The flower cohlifts of one leaf, which is of the funnel fafhiohed kind : its tube is of the length of the cup : the verge is partly erecr, but expanded, and is divided into four, five, or fix obtufe fegments. The ftamina are pointed filaments of tha length of the tube, and of the fame number with the fegmthts of the flower. The apices are fimple : the gerinen = of the piftillirai is found, and pointed at the end : the (file is pointed, and of the length of the tube of the flower, and divided into two parts at the end. Thefe fegments are again bifid, and the lligmata that terminate them are of an obtufe figure. The fruit is a drupe of the dry kind, and is of a glbbofe pointed form, and covered with the cup. The feed is a fincrle nut, furrowed on the fides, and divided info two fegmcins. Dill. Elih. 2-.'6. LinneciGcn. Plant, p. 520.
