series of soft spines setose on their sides. Lengtli of carapax in a 

 female, 0.85 ; breadth anteriorly, 0.43 ; breadth posteriorly, 0.90 inch. 



In habit, this species has a general resemblance to Phylloli- 

 thodes, and differs much from Hajyalogaster. It may be neces- 

 sary to separate it geuerically from Dermaturus., but we have 

 not seen the typical species of this genus of Brandt. 



It was taken from the stomachs of fishes caught off Monterey, 

 California, by Alex. S. Taylor, Esq. 



Hapalog^aster inermis, nov. sp. 



Carapax longer than broad, smooth above except where some minute, 

 transverse, setose scabrosities or minute squamae are sparsely distributed, 

 occurring most abundantly toward the sides. Margins unarmed, smooth. 

 No sinus at the juncture of the cervical suture with the lateral margin. 

 Rostrum convex above, almost carinated ; apex scarcely acute. Inner 

 orbital tooth minute, inconspicuous. Outer orbital tooth (antero-exterior 

 angle of the carapax) far less prominent than the rostrum. Acicle rather 

 short and broad, irregularly somewhat dentated along the exterior margin. 

 Feet subcylindrical, almost naked, rugose above with minute and some- 

 what setose tubercles ; dactylus three-fourths as long as the penult joint 

 and armed with a long unguiculus. Plates of the first joint of the 

 abdomen narrow. Length of carapax, 0.4; breadth posteriorly, 0.38 

 inch.

PAGUEOIDEA. 

 Diipag^iirus annulipes, nov. sp. 



Carapax rather depressed, smooth, naked above. Eyes nearly as long 

 as the front is broad, and nearly reaching the tips of the peduncles of 

 the antennae ; they are somewhat constricted about the middle, and the 

 cornea is not dilated. External antennae longer than the carapax, but 

 not reaching the tips of the ambulatory feet ; flagella sparsely clothed
