are devoid of dorsal spines and the gastric region is armed anteriorly with 
two small teeth in the median line. The specimen was afterwards described - 
and figured with more detail by G. O. Sars.* The third and fourth abdomi- 
nal segments are represented as armed with dorsal teeth, similar to, though 
shorter than, those of G. brevispinis, while the gastric region appears unarmed. 
The specimen was in a bad state of preservation when it reached Professor 
Sars, and Suhm’s figure, which was probably drawn soon after the capture, is 
presumably correct as far as the gastric teeth are concerned. ‘The “ Albatross” 
specimens appear to be specifically distinct from the ** Challenger” species, 
and may be diagnosed at once by the prominent dentate gastric crest, the 
small size or even absence of the lower spine of the infero-posterior 
angle of the carapace, and the great breadth of the antennal scale. The 
pleure of the first four abdominal segments are expanded posteriorly into 
rounded lobes. A deep transverse dorsal fold separates the two dorsal spines 
of the second segment of the abdomen. 
Wood-Mason describes the dorsal spines of the first abdominal somite of 
G. brevispinis as subequal. In the “ Albatross” specimens the anterior of 
these spines is at the best only half as long as the posterior one. 
G. brevispinis was first obtained in the Bay of Bengal (690-1748 fathoms) 
by H. M. Indian Marine Survey Steamer “ Investigator.”
