BARBADOS-ANTIGUA REPORTS 85 
is about half as long as the third, and the second and third together 
equal a little more than half, but not two-thirds the length of the visible 
portion of the first segment; the antennal peduncle is shorter than the 
eye-stalk, and in ventral view fails of reaching the distal margin of the 
basal segment of the antennular peduncle; antennal scale when directed 
straight forward about reaching the penultimate, dorSal, rostral tooth, the 
sharply angled inner, anterior ‘‘corner’’ of the blade is produced a little 
in advance of the spine. 
The mandible is without a palp, and the third of the three maxillipeds 
alone, without an exopodite; the second, left maxilla somehow strayed in 
dissection, and the figured right seems to have lost its inner lobe or lobes, 
if present at all, though I suppose they must have been. 
Chela of first legs slightly longer than the carpus and about seven- 
eighths the length of the merus; fingers a little more than two-thirds of 
the palm; there is a tuft of short hairs near the inner, ventral, posterior 
angle of the palm and another on the infero-distal angle of the carpus; 
only the left leg of the second pair is present, its fingers are long and 
slender, hooked at the tips and without teeth on their cutting edges, the 
movable finger is a little longer than the rest of the hand and the carpus 
taken together, the carpus two-fifths the length of the palm and very 
little longer than deep, merus a little more than four times the length 
of the carpus; ambulatory legs similar, dactyls slender, biunguiculate, 
without basal protuberance; dactyl of third leg slender, about two-fifths 
the length of the propodus and nearly half as long as the carpus; the 
carpus equals three-fourths the length of the propodus and about half or 
slightly more than half the length of the merus; propodus armed below 
with eight spines, including the one at the infero-distal angle. 
The fifth and sixth abdominal somites are about of equal length, either 
being slightly less than half the length of the telson; abdominal pleura 
rounded beneath; telson long and narrow, tapering to the distal margin 
which is but one-fourth the width of the base of the telson; medially the 
telson is deeply sulcate, on the lateral ridges thus formed, there are two 
pairs of dorsal spines, the distal pair of which is just before the middle 
and the proximal pair at about one-sixth the length of the telson from 
its base; the sides, lateral margins, are about perpendicular to the dorsal 
surface; the distal margin of the telson is armed with two stout movable 
spines, attached to the middle of either half of the posterior margin, in 
width equalling one-fourth the length of the margin, and in length slight- 
ly exceeding it; at either postero-lateral angle is a small, slightly, in- 
wardly curved spine in length equalling half the width of the adjacent 
large spine; between the pair of large spines are two slender, broken 
spines, or thick, stiff hairs diverging from either side of the slightly 
peaked mid-point of the posterior margin, the remaining portion of the 
longer of these slender spines is as long as the basal width of the large 
spines; the dorsal spines of the telson though as long as the posterior 
large spines, are much more slender, being half or less than half as thick 
or stout.
