scattered tubercles, six or eight on the branchial region, four or five 
on the mesogastric, two or three on the gastric, and a row near the pos- 
terior margin. The rostrum and the inner and outer orbital angles 
are about equally advanced. Orbital angles acute. 
Antero-lateral teeth five, the first three prominent, acute, the fourth 
smaller, the fifth almost obsolete. Sinus between the second and third 
not so deep as between the first and second, making a partial coales- 
cence of the second and third teeth, which, however, is very slight as 
compared with the coalescence of the same teeth in aculeata and lher- 
minieri, where the second tooth is much more feebie than the first and 
third. 
Basal article of the antenna with a shallow emargination on its 
anterior border outside the insertion of the second article, which is 
narrower than in lherminieri, the outer lobe produced forward but little 
beyond the inner lobe. Remaining articles wanting in our specimens. 
Appendages of the male abdomen in contact at about three-fifths of 
the distance from the distal end, then separating slightly in faint curves 
concave to each other, and again converging before they finally spread 
out at the tips. Distal three-fifths yellow, very slender, tapering grad- 
ually to a fine point (pl. xxxv, fig. 2). 
Chelipeds small, longer than the first pair of ambulatory legs. Merus 
somewhat angled, unarmed. Palms about one and a half times aslong 
as broad, tapering slightly toward the distal end. Fingers with distal 
half minutely dentate and in contact; proximal ends gaping, a slight 
tooth at the base of the dactyl. Ambulatory legs short, sparsely hairy, 
a longitudinal depression on the carpal joints as in aculeata. 
Length, 14.2 millimeters; width, 14 millimeters; width of front, 8,7 
millimeters. 
RECORD OF SPECIMENS EXAMINED, 
Near Charleston Harbor, 1 to 12 fathoms (3158). 
Blackfish Bank, off Charleston, 12 fathoms, from stomach of fish (5755). 
An egg-bearing female from Jamaica, T, H. Morgan, 1891, has been 
doubtfully referred to this species. The carapace is wider. posteriorly 
and narrower in the center, sparsely pubescent. The basal antennal 
joint is dentate on its anterior margin. 
Othonia nicholsi, sp. nov 
Plate xxxv, fig. 3. 
Carapace oblong, outline of anterior portion much as in aculeata, 
broader posteriorly. Carapace with strongly marked tubercles of 
which the larger are arranged as follows: Two on the median line of 
the mesogastric, the anterior one the smaller; two transversely on the 
anterior part of the cardiac region; three or four on each branchial 
region, where they have a tendency to become spiny. Of smaller 
tubercles, there is one on each gastric lobe, two transversely at the
