In the typical form the short rostrum overhangs the face like a hood. 

 Upon two species with rostra like this, Bate based his genus Tropiocaris.^ 

 T. planipes, the type of the genus, appears to be the same as Smith's Eph^rina 

 benedicti.f Neither Ephyrina nor Tropdocaris seem to be separated from Acan- 

 thephyra on sufficient grounds. 



A. curtirostris in its typical form resembles A. temdpes (Tropiocaris icnuipcs 

 Bate), but judging from Bate's figure and description, it differs from the 

 latter in the following regards : the presence of a prominent tooth on the 

 lower edge of the rostrum, and a dorsal carina on the second abdominal seg- 



ment 5 the great prominence of the tubercle on the inner side of the eye- 

 stalk ; and the shape of the antero-lateral margins of the carapace, which 

 are much less oblique than in A, temdpes,
