the West Indian form, and confirms the belief that the species 

 is identical with Parthenope [Parthenomerus) efflorescens' 

 Alcock, from the Andaman Sea, 36 fathoms. Two males 

 were taken by the University Expedition, off Havana. 



CANCRID^. 



58. Carpilius corallinus (Herbst), 

 Spanish Wells, Bahamas. 



59. Liomera longimanus A. Milne Edzva?'ds. 

 Tortugas. 



60. Act^ea setigera {Milne Edwards'). 

 Tortugas. 



Act^ea bifrons sp. nov. PI. iv, Figs 3 and 4. 



Allied to A. setigera ; front double; fingers smooth. 



Carapace narrower and flatter than in setigera; areolations 

 similar, granulation finer, marginal lobes more angular. Front 

 (Fig. 3), with a double edge, the inferior slightly in advance 

 of the superior, but scarcely noticeable in a dorsal view; the 

 two lobes of the superior margin are slightly arcuate, margin 

 denticulate or granulate; the lower margin viewed from in 

 front is sinuous; surface between the two margins, concave. 

 The epigastric region is coarsely granulate. Eyes larger 

 than in setigera; inferior orbital margin with a prominent 

 tooth at the inner angle. The chelipeds differ from those of 

 setigera in having the fingers longer in proportion to the palm, 

 more strongly bent downward, the pollex wider at base than 

 the dactylus. The fingers are horn-color and are almost 

 smooth, being marked with lines of shallow pits; in setigera, 

 on the contrary, the grooves on the fingers are very deep and 

 the intervening ridges are narrow and armed with conical 

 tubercles. The hairs which cover the surface are dark-brown; 

 in setigera, yellow. 



Dimensions. — Male, length 5.5, width 8 mm.
