 ^ Without setting forth the copious references to this genus in 

 itr enlarged and restricted acceptations, I will recommend the 

 reader to consult Dr. Bigelow's paper above cited, only here 

 taking from it the generic diagnosis : — 



" Stomatopoda having the telson attached to the sixth abdomi- 

 nal segment by a movable joint; the hind body depressed and 

 wide ; the dactylus of the raptorial claw with usually not more 

 than six teeth; as a rule, more than four intermediate denticles 

 on the telson, which is usually longer than wide ; and the inner 

 basal spine of the uropod the longer of the two."

I borrow the references and accept the specific name from Dr. 

 R. p. Bigelow's excellent account of the species. With some 

 reason he appends a note of interrogation to its identification 

 with the form named by Milne^Edwards and Gay. Milne- 

 Edwards only says, '' this species is extremely near to Squilla 

 mantis, from which it is distinguished by the absence of crests on 

 the carapace, and by the presence of two spiniform teeth on the 

 upper face of the ophthalmic ring; the claws have seven teeth; 

 length, three inches and a half ; habitat, the coasts of Chili." Dr. 

 Bigelow's specimens were from various stations ofif the coast of 

 Patagonia, had the dactylus of the raptorial claw " armed with 

 seven to nine teeth, rarely six," and varied in length from 60 to 

 122 mm-; they are described as having the "carapace with 

 median carina obsolete or entirely absent, intermediate and 

 lateral carinse present on the posterior lateral lobes, anterior 

 lateral angles produced into acute spines.''' In the South 

 African specimen there is one pair of distinctly marked though 

 not strongly raised carinse, and the dactylus of the claw has six 

 teeth in addition to the terminal tooth. Apart from the above- 

 mentioned carinae, it agrees in all respects with Dr. Bigelow's 

 description, and the telson, which he figures, is in this species 

 rather peculiar. It has " a crest and a keel and a series of curved 

 lines of pits on each side, six marginal spines, the submedian pair
