164 BULLETIN OF THE 



Echinocerus diomedeae, sp. nov. 



Carapace subpentagonal, gastric and branchial regions inflated, the whole 

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

 rather more prominent tubercle in 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; the chela? are of unequal size (the right 

 being the larger), setose, spiny on the 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 paix' are toothed c te ior margin, the propodus of the third pair is 



also toothed 01 th< po rgin ill - nents are hirsute, especially 



the daciyli. When the legs are closely fol idi of the carapace 



a wide interval is left between th< eheliped irst pair of am- 



bulatory stpj ided by the. op] hese segments, and 



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

 lar to that seen in E. foraminatus Stimp&^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. foraminatus 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 setse. Rostrum 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.
