scribed, and that my genus is synonymous with bis as indicated above. 

 My Bhachocaris Agassizii is apparently synonymous with Milne-Edwards'a 

 G. aouleatum, but the two other species which I have described are ap- 

 parently specifically distinct from the species figured by Milne-Edwards,- 

 and shoukl stand as Glyphocrangon sculptus and longirostris. 



The structural peculiarities of the genus pointed out in my original 

 description are, I think, sufiflcieut to warrant its separation from the 

 typical Craugonidae as a distinct family.

Specimens examined. 



This species was originally described from a single female, which dif- 

 fered slightly from the usual form of the species as shown in the series 

 of. specimens enumerated above. The large verticall^^-compressed 

 tooth at the extreme anterior end of the lateral lobe of the gastric re- 

 gion is usually more regularly acute than shown in the figures of the 

 original specimen, and the anterior tooth of the middle lateral carina is 

 acute instead of bidentate at tij). The males are considerably smaller 

 than the females, but do not differ essentially, except in the usual modi- 

 fication of the pleopods and of the base of the major flagellum of the 

 antennulse.
