Mantissa Insectorum sistens eorum species nnper detectas adjectis cliaractcribus 

 genericis, differentiis specificis, emendatiouibus, observationibus. Tom. I. Hafnige 



MDCCLXXXVII. 



The Agouata here comprise seven genera, Cancer, Pagums, Hqyjpa, Scyllarus, Astacus, Squilla, 

 Gammarus. Gammarus contains the same list of species as in the Species Insectorum of 

 1781, with the addition of Gammarus gihhosus. The reference to its synonym Oniscus 

 gihhosus in the earlier work is misprinted 577 for 377. Cancer linearis, Pennant, is 

 given as a synonym of Gammarus longicornis. Oniscus Ucaudatus is retained among the 

 Synistata, where also Ctjamus is stiU represented by Oniscus ceti.

On pp. 20-21 is described Squilla ventricosa, "Sqviilla rubra depressa, pedibns quatuordecim 

 setaceis secundo pari clavato. Zool. D. jjr. 2360." On pi. Ivi. this is ligured together with 

 Squilla quculrilobata. For the latter, on pp. 21-22, references are given to "Zool. D.pr. 2359.'* 

 "Faun, groenl. 225." "Act. helv. .5. p. 368." "Cancer atomos, Linn. Sijst. p. 1526." 

 " Brit. ZouJ. 4, p. 17 f. 32." " Easter subsecis, i. t. 4 f. 2." " Oniscus Scolojjendroides, Pall, 

 spicil. 9. p. 78." The description is followed by these remarks : " Descriptio Cancri ZzwearfV 

 et filiformis Linneani, synonymonque a Marteris petitum nostra Squillse aeqiie conveniunt, 

 at citata Easteri figura Cancrum cdomum esse jubet ; in aquis dulcihus Jiuctuantihis 

 habitare hallucinatione dictum est ; cur in fiuctuantihus uon percipio. Cauda in figura 

 Basteri certe errore delineata Linneum, ut has species cauda prorsus carentes rnacrouras 

 seu longicaudas diceret, seduxit. Exactissimam clariss. viri Pallas, Gronovius et Otho 

 Fabricius descriptionem dedere ; ille a Cancro jure semoveus Onisco junxit, hie mecum

 Animal Zeylonicum G. de Riville in Mem. de Mathem. et Physique vol. 3 et Berl. Saraml. 

 vol. 9. p. 42, t. 1, f. 6 nostram vesiculis orbatam sistit." Miiller's indignation at seeing the 

 name Gammarus, which belonged specifically to that " very large insect," the common 

 lobster, applied to a genus of " very minute " shrimps, does not appear wholly unreasonable. 

 But if Fabricius committed an error of judgment in this respect, it is too late now to 

 correct it.
