COROCORO, in zoology, the name of a Brafilian fifh, fome- what refembling the coracinus of the Mediterranean. Its back is prominent and crooked, and its nofe obtufe; its teeth fmall, and notfharp: the coverings of its gills are large, and terminate in a very fharp fpine. It has fix fins, twcTbehind the gills ; two others, of a fomewhat triangular figure, under the belly ; thefe have before them a very itrong and fharp fpine; and one behind the anus, with a very thick, flrong, and pointed fpine, with another very fmall fpine ftandingjuft be- fore it. The back fin begins about the middle, and runs a good way down the back : this is fupported by prickly rays ; and where it terminates, there immediately begins another lower and fofter fin, which reaches to the tail. Its fcales are confiderabiy large: its back is of a pale brownifh white: all the reft of the body of a fine 1 filvery hue, but that the fides have a few tranfverfe pale brown lines. Its belly, and belly fins, are perfectly white ; and it has a fmus in the back, in which, at pleafure, it can bury the fins. Marggraveh Hift. Brafil.

The glume has two valves, and contains only one flower : the Valves are oblong, obtufely pointed, and equal in fize. The flower is compofed of a fingle valve, in figure and fituation much refembling the valves of the cup. The itamina are three capillary filaments, and the anthene are oblong. The germen of the piftillum is of a turbinated form : the ityles are two in number, and very (lender : the ftigmata are fibrofe. The flower contains the feed, which is fmgle, of a turbinated form, and convex on one fidej and plain on the other. Linnai Gen. Hlant. p. 13.

1 he difference between a corodv and penfion is faid to be, that a corody is allowed towards the maintenance of any of the king's fervants in an abbey; but a penfion is given to one of the king's chaplains, for his better maintainance, till he may be provided with a benefice. See Fitzherb. Nat. Br. fol. 250- who fets down all the corodies and penfions certain, that ab- beys, when they flood, were bound to perform to the king.

four leaves of an oval figure, of different fizes, coloured, and falling with the flowers, of which it bears the peduncles. The feparate perianthia belonging to each flower are fmall, notched into four fegments, fituated on the germen of the piftillum, and falling with the flower. The flower conhfts of four very fmall petals, oblong and pointed. The itamina are four erect pointed filaments, longer than the perianthium, and the an- thers;, which are roundifh, lie on them. The germen of the piftillum is roundifh, and placed below the calyx : the ftyle is ilender, and of the length of the Itamina : the ftigma is ob- ; tine. The fruit is an umbilicated roundifh drupe. The feed \ is an oblong cordarcd nut, containing two cells, the kernel I being oblong. Linn si Gen. Plant, p. 48. The cornus is what we call the cornel-tree. Its characters, ac- cording to Tournefort, are thefe: the flower is of the rofa- , ceous kind, being compofed of feveral petals, difpofed in a cir- ' cular form, the cup of which finally becomes an olive-map' d fruit, or elfe a roundifh one : thefe are foft, fleihy, and con- tain a nucleus, divided into two cells, with kernels.

COROLLIST/E, among the botanical authors, are thofe who have attempted the eftablifhing the clafles and diftinctions of plants, on the different form of the corolla, or leafy part of the flower, without paying the due regard to the apices, Itamina, and piftillum, the parts of fructification contained within it. Of thefe are Rivinus, and the great Tournefort. Limuei Fund. Bot. p.

CORNUTIA, in botany, the name of a genus of plants, called by Vaillant agnantbus. The characters arc thefe : the perian- thium is very fmall, of a roundifh figure, and confifling only ot one leaf: it is divided into five fegments at the end, and re- mains when the flower is fallen. The flower is compofed of one petal, and is of the gaping kind : the tube is cylindric, and much longer than the Itamina : the edge is divided into four parts, the upper fegment being erect and roundifh, the iide ones Handing diftinct from one another, the lower one being roundifh and undivided. The Itamina are four fila- ments : the anthers are fimplc, and inclined : the germen of the piftil is roundifh : the ftyle is very long, and divided into two parts : and the ftigmata are very thick. The fruit is a globofe berry, adhering to the bottom of the cup, and con- taining one feed of a kidney-like fhape. LinnaiGttt, Plant. p. ^C2. Plumier jy, Vaillant, A. G. 1722.

CORNUTUS pifcis, in zoology, a name given by Mr. Ray to the fiih commonly called by the Dutch in the Eaft-Indies, where it is very common, hoorn v'feh. It has a horn of a ve- ry Angular kind in the back part of its head, or beginning of its back, and two others on the belly : thefe are crooked, and very brittle. They feem much of the nature of the fpines, which feveral fifh have placed before their back and belly fins;

■ and it is dangerous to be wounded by them, the wound being generally very difficult of cure, cfpecially if any part of the horn or fpine is left in it, which, from the brittlenefs of thofe fubftances, is generally the cafe.

Corona, among botani Its, exprefles any thing growing on the head of the feed. The cor ones of feeds are of various kinds ; fometimes fimple, confifling only of a dentated membrane ; fometimes pappofe, confifling of downy matter, which in fome cafes is immediately fixed to the feeds ; in others it has a pedicle growing from it. Sometimes the corona are com- pofed of fimple filaments, and fometimes they are rarnofe.

Corona imperialis, in conchy liology, a name given by authors to a kind of valuta, differing from the other fhells of that fa- mily, by having its head ornamented with a number of points, forming a fort of crown. See Voluta. There are four fpecies of this fhell found in the cabinets of the curious: I. The common kind. 2. The corona imperialis, with fewer and fmaller fafefee, or circular lines. 3.

Corona imperialis, crown imperial, in botany, the name of a genus of plants, the characters of which are thefe : the flow- ers are collected into a fort of crown near the top of the flalk, and have over them a large tuft of leaves.
