164 BULLETIN OF THE 



Echinocerus diomedese, sp. nov. 



Carapace subpentagonal, gastric and branchial regions inflated, the whole 

 surface beset with tubercles which give rise to minute setae. There is one 

 rather more prominent tubercle iu the depression on each side of the gastric 

 area. Rostrum short, three-spined ; one of the spines is median and inferior, 

 two are paired near the base above; in one of the two specimens obtained the me- 

 dian spine is toothed below. The antero-lateral margin of the carapace is irregu- 

 larly toothed. Eyestalks spinulose above, with one prominent spine projecting 

 forward over the cornea. The movable scale or spine of the antenna is spinu- 

 lose on each side (four or five spines on each margin). The merus of the cheliped 

 bears a spine on the inner side at the distal end ; the carpus is smooth outside, 

 the inner border expanded into a seven-toothed crest setose within, the outer 

 border straight, naked, and keeled; tbe chelae are of unequal size (the right 

 being the larger), setose, spiny on tbe upper edge; fingers spoon-shaped within, 

 setose and somewhat gaping. Ambulatory appendages: the meri are spinose 

 on their edges; the anterior border of the carpus of the first pair is furnished 

 with a crest whose edge is even and entire; the propodus of the first pair is 

 crested along the proximal half of its anterior border, while the distal half is 

 armed with two or three teeth ; the carpus and propodus of the second and 

 third pairs are toothed on the anterior margin, the propodus of the third pair is 

 also toothed on the posterior margin; all the segments are hirsute, especially 

 the dactyli. When the legs are closely folded against the sides of the carapace 

 a wide interval is left between the carpi of the cheliped and first pair of am- 

 bulatory appendages, bounded by the opposite crests of these segments, and 

 forming a passage for the admission of water to the gills. This orifice is simi- 

 lar to that seen in E. foraminutus Stimps., but it is not so perfectly formed 

 The apex of the abdomen (in the female) is turned to the right (most strongly 

 in the larger specimen); the marginal plates are wanting on the left side; all 

 the abdominal appendages excepting the first are aborted on the right side. 



Length, 64 mm.; breadth, 71 mm. 



Station ,3384. 458 fathoms. 1 female. 



Station 3394. 511 fathoms. 1 female ovig. 



In this species the acicle of the antenna is spinous on the margins only, as 

 in E. foraminutus Stimps. 



Paralomis aspera, sp. nov. 



Carapace pentagonal, as broad as long; gastric, cardiac, and branchial regions 

 well defined and prominent ; whole surface of carapace and abdomen thickly 

 beset with papillae or tubercles, each one of which is encircled with a crown 

 of stiff sette. Ro.strum short, indistinctly tripartite, multispinose. A sharp 

 dark-tipped spine at the external orbital angle, another at the antero-lateral 

 angle of the carapace, and four or five, irregularly arranged, on the margin of 

 the branchial region.
