posterior border of the carapace. The eyes are smaller, their diameter being 

 not nearly twice that of the eyestalk. The tubercles that carry the openings 

 of the oviducts are perhaps even larger, and the thelycum differs, the most 

 conspicuous difference being the replacement of the large shield-shaped tubercle 

 by a narrow pointed tubercle. The lobes of the " andricum " end in three 

 sharpish lobules of not very unequal size. 



Colour in life bright orange, in spirit rusty yellow.

The only differences between this species and H. sequalis are the following : — 

 The eyes are small, being hardly wider than the eyestalk. The last 2 

 pairs of thoracic legs, though equally filamentous, are shorter, the last pair 

 being as long as the carapace and rostrum together with the first five-and-a-half 

 abdominal terga. The three lobules at the free end of the lobes of the 

 " andricum " are very unequal in size, though the inner one is nicked at the tip 

 in the same way. 



Colour in life purple-black, the eyes very black ; colour in spirit reddish or 

 brownish. 



In our largest specimen the rostrum and carapace together measure 26 

 millim., and the extended abdomen 40 millim., in the mid-dorsal line.

Glabrous, leathery. Rostrum straight, little ascendant, reaching to the end 

 of the 2nd joint of the antennular peduncle, its free portion about a third the 

 length of the rest of the carapace measured in the mid-dorsal line : its carina, 

 which behind the cervical groove is low broad and blunt, is continued nearly to 

 the posterior border of the carapace, being interrupted at the cervical groove and 

 twice, broadly, behind it. The rostrum is armed dorsally with 7 or 8 nearly 

 equidistant teeth. The cervical groove and the groove defining the branchial
