Differs from G. investigatoris only in the following particulars: — 



The length of the free portion of the rostrum is more than four- fifths that 

 of the rest of the carapace measured in the middle line, and the anterior of the 

 lateral spines of the rostrum is a good way behind the middle : the anterior half 

 of the rostrum is foveolate dorsally on either side of the very faint median 

 longitudinal ridge. 



The 3rd or dorso-lateral crest of the carapace ends in a small spine. 



The tubercles between the crests of the carapace are very much smaller and 

 less numerous, in fact are mere granules which, on the lateral regions especially, 

 are quite inconspicuous. On the abdominal terga also they are less numerous, 

 and on the abdominal pleura more confluent. 



The antennular peduncle hardly reaches beyond the antenna! scale, and the 

 antennular flagella are longer. 



The second pair of thoracic legs are decidedly shorter than any of the last 

 three pairs, and reach only to the end of the antennal scale. 



Colour in life bright crimson. 



Length of carapace and rostrum 34 millim., of abdomen 42 millim. 



Bay of Bengal, near the Andamans, 561 fathoms ; Andaman Sea, 188-220 

 fathoms ; Arabian Sea, off the Maldives, 459 fathoms.

 Illustrations of the Zoology of the Investigator, Crustacea, Plate VI. Fig. 1. 



Differs from G. investigatoris only in the following particulars : — 



The free portion of the rostrum is more than three-fourths the length of 

 the rest of the carapace measured in the middle line, and the anterior of the 

 lateral spines of the rostrum is a good way behind the middle. 



The crests of the carapace are thinner, and the tubercles between them 

 are very much smaller and less numerous, being little more than scattered 

 granules. 



The 2nd or " subdorsal " crest of the carapace is as distinct in its anterior 

 as it is in its posterior half, and is sharply serrated throughout, its spines being 

 compressed and the front one being larger thai; the rostral spines.
