The Linnean Cancri are numerous, and include many fpecies not lefs fingular in appearance than the 
extraordinary creature before us. Indeed, fome fpecies are fo extremely different from the reft, both in 
ftructure and manners of life, that we cannot hefitate in concluding the Linnean charaéter of the genus 
defective and indefinite. This may be obferved in feveral of the fpecies Linnzeus himfelf defcribed, and 
throughout a more extenfive number of thofe difcovered fince the time of that author. It is evident 
Linnzus could never reconcile the fubdivifions of the two principal families; the Brachyuri and Macrouri; 
or crabs with fhort and long tails; and later naturalifts have ventured, with propriety, to alter this part of 
his arrangement. The Pagarus, Hippa, Scyllaris, Aftacus, Squilia, and Gammarus, are fo many new 
genera, formed of the Linnzan tribes of Cancri in the latt Syftem of Fabricius. The genus, to which 
Fabricius retains the name Cancer, is diftinguifhed from the reft, by having four fhort filiform antenne ; 
with the extreme articulation bifid, as we obferve in the preceding fpecies. This author follows Degeer 
in defcribing the Cancer Mantis, and alters the generic name to Squilla: he obferves, that this genus is 
entirely diftinét from the Cancr7, and we are of the fame opinion, but adhere to the Linnean genera, be- 
caufe the {pecies, Mantis, was defcribed by Linnzus, and it may be improper therefore to remove it, to a 
new genus, in any partial furvey of his fyftem. The Cancer Mantis is not peculiar to China.
