Histoire naturelle des Crustaces, contenant leur Description et leurs Moeurs. 

 2 vol. Paris. An X. (1802). 



The first edition of this work has some historical interest, as being perhaps the first popular 

 treatise ever written in the vernacular on Crustacea. The introduction remarks on the 

 extreme and unjust neglect which had been shown by science to this branch of natural 

 history. The author remarks that the Greek and Latin writers, as Aristotle, Athenseus, 

 Hippocrates, and Pliny, had all considered the ilalacostraca as fish, or intermediate between 

 lish and shell-fish, that the earliest modern naturalists who had written upon them, such as 

 Rondelet, B(51on, Gesner, Aldrovandus, Jonston, had placed them immediately after fish or 

 MoUuscs, that even the great Linuceus, who classed them with apterous insects, had left 

 their genera and species in its primitive chaos, merely distinguishing Crustacea Jxrachyura 

 from Crustacea macroura, and leaving out of sight ahnost all the minute species. The 

 improvements in classification introduced by Fabricius, Daldorf, MiiDer, Geoffroy, Cuvier, 

 Lamarck and Latroille, are then explained. An account follows of the difierent organs of 

 the mouth and the limbs, of the muscles as described by Cuvier, of the viscera after Roesel, 

 of the renovation of limbs, and the phenomena of exuviation after Eeaumur. In regard to 

 the fierceness and size of Crustacea in warm countries there is a remark worth citing in the 

 words of the original, " on dit qu'ils sont d'une grandeur si d^mcsur^e, qu'ils attaquent les 

 hommes, et en ont mangd plusieurs, entre autres le fameux navigateur Francois Drack, qui, 

 quoique arme, ne put ^viter ce sort." Of this great sailor's death on the Isthmus of Darien, 

 Hume says, " Drake himself, from the intemperance of the climate, the fatigues of his 

 journey, and the vexation of his disappointment, was seized with a distemper, of which he 

 soon after died." A rationalist would perhaps attempt to reconcile the two accounts by 

 suggesting that Drake may have died of cancer. 



Of Amphipods Bosc gives four genera, Gammarus, Fabr., TaVdrus, Latr., Caprella, Lamarck, 

 and Cyamus, Latr., with coloured figures of one species of each genus on pls). xiv., xv., and 

 xvi. He describes one new species from North America, Talitre grillon, Talitrus grillus, 

 with the reference " voyez pi. 15. et fig. 2." At the foot of pi. xv. we read, " 1. 2. Thalitre 

 terrestre." In accordance with the suggestion of Milne-Edwards, Spence Bate, in the Brit. 

 Mus. Catal., names this Orchcstia gryllus, with a synonym " Scarnhalla Sayana, Leach, MS." 



Bate and Westwood, vol. i. p. 14, note that the name Talitrus first appears in the year 1802, 

 both in Latreille's Hist. Gen. des Crust, et Ins., vol. iii., and in Bosc, vol. ii. the latter 

 writer giving Latreille the credit of the invention, while LatreiUe subsequently, in 1806, 

 refers the genus Talitrus to Bosc as its author. This may be explained by the fact which 

 Bosc mentions, vol. i. p. 48, that Latreille had given him permission to use the classification 

 of Crastacea which the lender had prepared for a new edition of his own work. Thus 

 Latreille's Talitrus makes its first appearance in Bosc's treatise. It is defined as follows : — 

 " Quatre antennes simples ; les intermediaires, sup(5rieures, plus courtes que le pedoncule 

 des inferieures. Corps along^, convert de pifeces crustacees, transverses, presque ^gales, et 

 appendicuMes sur leurs cot^s. Dix a quatorze pattes; les ant(5rieures termin^es par des 

 mains. Des appendices bifides h, I'extremite du corps."
