Cyrtomaia lamellata, sp. nov. 
A small species. Resembles much the preceding. Carapace wider. Spines of carapace long, as 
in C. smithi of equal size, not as in C. smithi adult; thirteen long spines, three gastric, two cardiac, two 
branchial (one behind the other), one exorbital, one marginal hepatic; a row of short spines just 
below the epimeral suture and a short row subparallel and above it. 
Rostral spines very short; the median subrostral projection thin, laminar, upper surface longitudi- 
nally concave, tip broken off in all our specimens. Upper margin of orbit much thickened. Eye- 
stalks longer and slenderer than in the preceding. Basal antennal joint armed with three laminar 
branching spines; next two joints laminately expanded in three directions. 
Chelipeds and legs much as in young of C. smithi. 
Dimensions. — Male, station 4046, approximate length to median sinus 13, width 13.8 mm. Ovig- 
erous female, station 3838, length to median sinus 13.1, width 12.7 mm. 
Distribution.— -South coast of Molokai Island, 92 to 212 fathoms, station 3838 (type locality); west 
coast of Hawaii Island, 147 to 71 fathoms, station 4046; northeast coast of Hawaii Island, 83 to 113 
fathoms, station 4062. Cat. No. of type, 29701. 
The presence of two branchial spines and absence of a supraorbital spine easily separates the spe- 
cies from C. smithi. 
Oncinopus aranea (de Haan). 
Oncinopus aranea Alcock, Jour. Asiat. Soc. Bengal, LXIV, 1895, 183, and synonymy. 
Odnopus aranea Borradaile, Failna and Geogr. Maidive and Laccadive Arch., II, 685, text fig. 123, 
1903. 
Distribution.— Vicinity of Kauai Island, 68 to 179 fathoms, station 4128; vicinity of Modu Manu, 
33 to 71 fathoms, stations 4149 and 4164. 
Sphenocarcinus carbunculus, sp. nov. 
(PI. xiv, fig. 6.) 
Posterior two-tbirds of carapace covered with nine large raised, button-like protuberances, regularly 
disposed, three median, on the gastric, cardiac, and intestinal regions, and three on each branchial 
region, of which one is at the postero-lateral angle of the carapace; these buttons are a little convex 
above, constricted below, and of a crimson red color except near the edge, which is whitish. A sim- 
ilar protuberance is on the side of the hepatic region, its anterior end being hollowed out inwardly to 
form a postocular cup. On the gastric region are three tubercles arranged in a triangle base backward.
