smooth and naked, except a line of hairs along the lower edge; a 

 single slender spine on the lower side of the ischium, and, on the 

 merus, several very small ones in the same position, and a large acute 

 one on the upper side a little way from the distal extremity ; carpus 

 short, a slight longitudinal sulcus on the outer surface, inner margin 

 denticulate and pubescent, with a small proximal and a large distal 

 spine, both directed forward, spines on the distal extremity at the 

 outer and inferior angles, and another on the inner side ; basal portion 

 of the propodus stout, subcylindrical, with longitudinal lines of 

 granules on the upper side, which give rise to hairs, and a slightly 

 oblique, narrow line of dense pubescence along the lower side ; pro- 

 podus but little shorter than the dactylus, nearly straight, tapering 

 to a slender point, smooth, naked, and the prehensile edge armed, 

 near the base, with two or three, small, obtuse teeth ; dactylus clothed 

 with long lines of pubescence and the prehensile edge armed with an 

 obtuse tooth near the base, and, near the tip, with a large slender one 

 which shuts just by the tip of the propodus; beyond this tooth the 

 extremity extends in a conical, horny tip about as long as the tooth. 

 Second thoracic legs ciliated along the inferior edge of the meri, and 

 along both edges of the propodi and dactyli ; merus compressed and 

 armed with a slender proximal spine on the inferior edge and a similar 

 distal one on the upper edge ; carpus unarmed, but slightly ciliated 

 within ; propodus broad and compressed ; dactylus short, triangular. 

 Third thoracic legs with a small spine above the genital orifice, a slight 

 one on the inferior edge of the ischium, and several on the inferior 

 edge of the merus ; dactylus, propodus, and distal portion of the carpus 

 'ciliated on the outer side and the inner edges; dactylus narrow and 

 about as long as the propodus. Fourth thoracic legs armed with 

 a row of spines along the inferior edge of the merus ; the three last 

 segments much as in the third pair of legs. Fifth thoracic legs 

 slender, subcylindrical ; propodus thickly ciliated on the anterior 

 side ; dactylus slender and very short. Abdomen ciliated along the 

 edges of the third, fourth, and fifth segments, but smooth and naked, 

 above. Appendages of the sixth segment with a spine above at the 

 articulation of each lamella; lamellae smooth and carinated above, 

 the extremity of the outer one slightly arcuate, that of the inner trun- 

 cate, but slightly rounded at the inner angle. Terminal segment 

 quadrilateral, broader than long, the dorsal surface smooth and naked, 

 with slight lateral carinations and a median sulcus. Length of a speci- 

 men, from tip of rostrum to extremity of abdomen 4.10 mra - Length of 

 carapax along the dorsal surface, 13.0. Length of hand, 9.5. 



A large number of specimens, all females, collected at the Island of 

 Aseredoras, twenty miles northwest of Corinto, Nicaragua, March 

 14th, and a few from the Gulf of Fonseca, May, 1869.
