On the upper margin of the orbit, between the supraocular eave and postocular lobe, there is a 
small spine which is larger in smaller specimens.

The upper margin of the orbit is not so deeply hollowed out as in Dana's figure and the tubercle 
either side of the cardiac region is larger. 
Chlorinoides goldsborougiii, sp. nov. 
(PI. XIV, fig. 7.) 
Surface granulous; two median gastric spines, one intestinal, two cardiac side by side, two large 
branchial, one of which is much further in and a little behind the other; the outermost, which marks 
the postero-lateral angle, has a smaller spine in front of it; two flattened lobes on margins of hepatic 
and branchial regions. 
Rostral horns about one-third as long as post-frontal portion of carapace. Supra-ocular eave with 
a subtruncate tooth at anterior and posterior angles, the latter less advanced than postocular spine; 
intermediate spine long. 
Basal antennal joint with lateral margins very prominent, each terminating in a slender spine, 
otherwise unarmed. 
Chelipeds of male nearly one and one- half times total length of carapace, stout; crests of arm and 
wrist irregularly dentate, a spine at distal end of arm ; chelipeds of female very slender and only as 
long as postrostral portion of carapace. 
Legs decreasing rapidly in length, first pair in male as long as cheliped less half of fingers, in 
female exceeding cheliped; meral, carpal, and propodal joints spinulous above, the meral joints each 
with three spines at distal end.
