Hub. Malacca: 5 fms.; muddy bottom. Eight males, seven 

 females : one of the latter carrying ova. 



In none of these does the epistome project farther than the 

 front ; the inner angles do, but in a greater or less degree in the 

 different individuals. Five of the males have the small tubercle on 

 the abdomen (P. globulosa) ; in the other three it is absent 

 (P. globosa) — yet in one of the males with a tuberculated abdomen 

 the whole of the upper surface of the arm is granulated except 

 near the tip (P. globosa), while in the three with no tubercle only 

 the proximal half is granular (P. globulosa) ; in all the females it 

 is entirely granulous except at the tip. The internal edge of the 

 exopodite of the external maxillipedes seems to show a gradation 

 from a nearly straight line to a slightly curved one ; but, curiously, 

 the nearly straight edge (P. globosa) is found in the males with 

 abdominal tubercle (P. globulosa), the slightly curved (P. globulosa) 

 on a male with no tubercle (P. globosa). In all cases the under 

 surface of the meri of the legs is smooth (P. globosa) ; equally in 

 all cases, the size of the granules on the edge of the carapace 

 varies (P. globulosa). The males with abdominal tubercles have a 

 low dentiform eminence at the base of the thumb, in those with 

 no abdominal tubercle it is absent ; this is the normal correlation 

 in P. globulosa and P. globosa respectively. The amount of 

 definition of the regions of the carapace varies from one to
