GUARIBA, in natural hiftory, the name of a fpecics of mon- key found in the Weft-Indies. It is of the fize of a fox,* Its face is railed high, its eyes are black and mining, and its ears fmall and round. Its tail is very lone, naked toward the end, and extremely moveable ; the creature frequently twilling it round things to faften itfclf by it. It is covered all over with fine black mining hairs, except on the legs and part of the tail where they are brown. The hairs are fo nicely difpofed all over the body, that the creature appears perfectly fmooth ; and they are much longer under the chin and throat, fo that they form a fort of beard there. Ray's Syn. Quad. p. 152.
This fpecies is found in prodigious numbers together in the woods, and makes a very loud and frightful noife ; and it is very common for one only to make a noife, and all the reft to form a mute aflembly round him. Marcgrave relates a very lingular thing of this creature, in this refpect, which he fays he has frequently been an eye-witnefs to. They, meet in great numbers before and after mid-day, when they form a large circle, and one placing himfelf above the reft, begins to. make a loud noife ; when he has fung thus by him- felf for fome time, the reft all remaining in perfect filence, he lifts up his hand, and they inftantly all join in a fort of chorus ; this intolerable yell they keep up inceflantly, till the fame monkey, who gave the fignal for their beginning, lifts up his hand a fecond time, on which they all ceafe and become filent again in a moment. He then exalts his pipe alone again, and fo finifhes the bufinefs of the aflembly. Thefe creatures carry their young upon their backs, and fkip very nimbly with them from tree to tree, the youn* ones clafping faft round their body with their arms. They are a very fierce animal, and can never be tamed. There is a fpecies of this kind alfo much larger than thefe, which have a very Jong black hairy beard. Thefe, as Marcgrave allures us, on his pofitive knowledge, will often attack the negro women as they go through the woods, and lie with them by force.

GUESDA, in botany, is properly the name of woad, but it is alfo ufed by fome for the lutum, or lutea berba of the Ro- mans, and cymene of the Greeks. This is an error in too many of the old authors, though fo palpable, that one would have thought no body could have run into it ; the lutum, or cymene, having been always ufed to dye yellow, and the glaftum, or gucjda, to dye blue ; and the characters of the lutum, or, cymene, plainly fhewing it to be our ge- ntjmla tinSioria, or dyers weed, but not at all agreeing with the glaftum, or woad.
