Hawaiian Islands (A. Milne Edwards). 
Eiconaxius asper, sp. nov. 
Near E. acutifrons Bate, E. crista-galli (Faxon) and E. caribbseus 
(Faxon). It resembles the first and differs from the second in the 
presence of a larger basal tooth on dactylus of larger hand and a 
more prominent tooth not far from middle of pollex. 
Resembles E. crista-galli and differs from E. acutifrons in having edges of rostrum distinctly den- 
ticulate, and median carina denticulate; in the abdominal pleura less sharply pointed; in the entire 
upper border of the hands, and the presence of a strong tubercle on the anterior border of the larger 
hand between the bases of the fingers. 
The outer and inner surfaces of the manus of both chelipeds are granulate, sparingly, and 
unevenly, but rather coarsely so, and the palms are higher in proportion to their length than in either 
of the related species. 
E. caribbseus has also an elongate palm and a more rounded rostrum. 
Distribution. — V icinity of Kauai Island, 418 to 528 fathoms, stations 3992 (type locality) and 3997. 
Found in sponge cavities. Cat. No. of type, 
30536. 
Color. — Lemon-yellow. 
Paraxius tridens, sp. nov. 
Carapace smooth, sloping abruptly down 
behind the front; a short median carina on 
the slope. Rostrum triangular, short, barely 
reaching end of eyes, a tuberculiform tooth 
either side. The three projections of the ros- 
trum are much sharper in the male, and the 
lateral teeth form short carinae. 
Abdomen smooth, with scattered hairs; 
pleura of first segment little developed, of sec- 
ond to fifth segments truncate, of sixth broadly 
rounded; sides of telson converging, four- 
spined, tip rounded. 
Eye-stalks short, stout; cornese large, 
black. 
Three joints of antennular peduncle sub- 
x 4f. equal, flagella half as long as carapace. 
Antennal peduncle twice as long as the an- 
tennular, unarmed; penult segment twice as long as last segment; flagellum as long as body. 
Outer maxillipeds stout, exceeding the rostrum by their last three joints; lower margin hairy, two 
spines on merus. 
First pair of chelipeds unequal in width, smooth, unarmed; merus of larger one about one-third 
longer than high; carpus higher than long; palm one and a half times longer than high, tapering very 
slightly toward the fingers, rimmed above and below, fringed with long fine hairs; fingers stout, 
blunt-pointed, not gaping. Narrower cheliped similar; carpus just as long as high; palm twice as long 
as high; fingers slenderer.
