converge on to the sides of the pseudorostrum ; between the crests the dorsal surface 

 is nearly flat. The ocular lobe is nearly twice as broad as long. The eye is without 

 pigment. 



The free thoracic somites have each a pair of dorso-lateral crests, in line with those 

 on the carapace, becoming indistinct on the last somite. The pleural plates of the 

 third somite are not greatly expanded laterally and there is no great interval between 

 the second and third pairs of legs. The abdomen is about as long as the cephalo- 

 thoracic region. The penultimate somite is little longer than the preceding. The 

 last somite is flattened and broader than lone 



The telson is a little shorter than the last somite and its breadth is five-sixths of its 

 length. 



The antennules have the first segment of the peduncle longer than the other two 

 together and the second more than half as long as the third. The outer flagellum is 

 composed of two segments, the inner of three. 



The antennae have three segments, the third longer than the preceding. 



The mandibles are of the usual shape. The maxillular palp is short and carries two 

 setae, both broken in the specimen dissected, but apparently unusually short. 



The first and second maxillipeds resemble those of G. carinata in having long setse 

 springing from the distal segments. The branchial apparatus appears to have n'o 

 lobules. 



The third maxilliped has no exopod ; the basis is little more than twice as long as broad, 

 slightly expanded and produced distally ; the propodus is shorter than the carpus. 



The first legs extend well in front of the pseudorostrum ; the basis is strongly bent 

 and is about half as long as the distal segments together ; the carpus is twice as long 

 as the two preceding segments together ; the propodus is less than half as long as the 

 carpus and bears a series of about nine very long setae on the distal part of its inner 

 edge ; the dactylus is little more than half as long as the propodus, and has one very 

 long and some shorter terminal sets. 



The second legs have the basis about twice as long as broad and a little longer than 

 the remaining segments together; the ischium is very short and easily overlooked ; the 

 dactylus is a little longer than the propodus and bears a short curved terminal claw ; 

 all the segments of the limb are setose, especially on the inner surface. 



The remaining legs are stout and subequal in length; the basis is about equal to the 

 remaining segments together; the merus is slightly inflated and longer than the last 

 three segments, which are very short ; the dactylus is curved and ends in a strongly- 

 curved claw. 



The uropods have the peduncle less than twice as long as the last somite and about 

 twice as long as the telson, thickened distally, where the diameter is about one-third 

 of the length, minutely setose, and with a distal spine internally. The exopod is a 

 little more than half as long as the peduncle and has a long and slender terminal spine. 

 The endopod is one and a quarter times as long as the exopod, of two segments, the
