Family CALLIANASSID^. 
CALLIANASSA GONIOPHTHALMA. 
Closely allied to C. csecigena Alcock and Anderson. Rostrum 
reaching- barely one-third the length of the eyes. No median carina, 
l^ut a slight blunt elevation near the posterior margin corresponding 
to the strong tooth in 61 cxcigena. Eyes oblong, sides subparallel, 
reaching nearly to end of first antennular segment. Chelipeds of the 
first pair shaped as in C. csecigena, but the carpus of the larger one is 
devoid of a spine, the palm is not serrated on its lower margin, its 
outer surface has a few tubercles irregularly disposed on the distal 
lower quarter; the poUex has on the cutting edge a stout tooth which 
is nearer the middle than in C. csecigena. The second to fifth seg- 
ments, inclusive, of the abdomen are without spines, the telson has 
subparallel side margins. 
Dimensions. — Length of carapace of male 30.5 mm., of abdomen 
67.5 mm. 
Type locality. — Off Point Conception, California, 278 fathoms, sta- 
tion 3198, U. S. Fish Commission steamer Alhatross., one male (Cat.

Family AXllD^. 
AXIUS SPINULICAUDA. 
Gastric region traversed b}'^ five caringe, all of which fade out before 
reaching the cervical groove; the median extends along basal third of 
rostrum and is armed with four spines; the outer carinse are a continua- 
tion of the side margins of the rostrum, and are unarmed, as are also 
the shorter intermediate carina3. Surface covered with rather distant 
scabrous granules. Rostrum reaches middle of second joint of anten- 
nular peduncle, is sharp-pointed, and has five spines on one side and 
six on the other. Second segment of antennular peduncle a little 
longer than the third, both together shorter than the first. The 
scaphocerite projects as far as the middle of the second segment of the 
antennula, the stylocerite to end of penult joint of antennal peduncle. 
First pair of chelipeds missing. Abdomen smooth above; pleura 
sculptured and pubescent; telson elongate, subquadrilateral, lateral 
margins spinulous, dorsal surface with a few spines; swimmerets 
spinulous. 
Dimensions. — Female, length of carapace and rostrum 19.6 mm., 
rostrum 3.5 mm., abdomen 31.5 mm. 
Type locality. — One specimen only, from off Bodega Head, Califor-
