I think there is little doubt of this animal beins; con* 

 generic with Cancer seorpioidesj described by Mmta- 

 gu in the seventh volume of the Trans. Lin, Soc, of 

 Load., and indistinctly i-epresented on plate sixth of 

 that instructive work. The general appearance, par- 

 ticularly of the posterior part of the body in that fignre, 

 its carve, t!ie caudal appendices &c., is very similar to 

 that of the species upon which I have constructed tliis;

 a mutilated specimen, but the only one he had seen ; 

 ^' the head or fore part was wanting, consequently no 

 eyes nor antenna* could be observed; but the mdiment 

 of arms on the fore part of the body" &c. Notwith • 

 standing these remarks of that intelligent observer, I 

 am led to believe, by comparing his figure and de- 

 scription with this animal, and judging from the ana- 

 logy between them, that it was nearly complete, want* 

 ing only the intermediate antennge. But it is neces* 

 eary to remark, that in our animal there is no distinct 

 head, unless that part of the body can be considered as 

 such, which I have called the first segment of the tho- 

 rax ; this is the more probable since neither of the five 

 pairs of feet which I have enumerated, are distinctly 

 perceived to arise from that part. It is true, that thosa 

 members which Mr. Montagu has called '' rudi- 

 ments of arms," most obviously have their origin there; 

 yet these, although much larger than either of the feet, 

 and r^quidistant from the two anterior pairs, I have sup« 

 posed, from their form and apparent position, to be m
