The anterior angles of the buccal frame are very promi- 
nent. 
The sub-hepatic and pterygostomial tubercles are papil- 
liform. 
The normal chelipeds in the male have the arm sub- 
cylindrical, the distal spine well developed, and with a well- 
marked tooth near the proximal end above. The carpus is 
strongly keeled outwardly, the proximal end very prominent. 
The palm is compressed, narrowing in the vertical direction 
towards the distal end. The fingers are moderately long, 
slightly curved, rather slender, finely denticulate, and ap- 
proximating for nearly their whole length. The enlarged 
cheliped sometimes occurs in this species in the males. 
The ambulatory legs are long, rather slender, sparingly 
setose, with the merus joints cylindrical ; the carpal and pro- 
podal joints nearly equal in length, the propoclal little ex- 
panded distally. The dactyli are slender, curved, and acute. 
The pleon of the male is narrow, the two fir.-jt segments 
more so, the third slightly wider than the rest ; their median 
portions are only very moderately prominent. 
This species may easily be distinguished from the former 
ones by its shrunken appearance, by the length of the lateral 
spines and rostral horns, its single tubercle on the cardiac re- 
gion, etc. In the position of the intestinal tubercle it 
resembles H. ar^ies. 
Length of carapace, 30 mm. 
Breadth of carapace, 20 mm. 
Length of rostral horn, 8 mm. 
Length of cheliped, 34 mm. 
Length of first ambulatory leg, 49 mm. 
Inter-ocular space, 6^ mm.

The next species is referred to the genus Faramicippa, 
M.-Edw. I have been able to compare it with P. tiihercu- 
lorn, M.-Edw., and find the following characteristics common 
to both. 
The carapace is rounded behind. The rostral horns are 
depressed, though not quite so much as in P. tuberculosa. 
The orbits are similar, although in P. tuhercidom the inter- 
mediate spine has disappeared, but is perhaps represented by 
the bifid, post-ocular spine. The eye peduncles are long, 
non-retractile, and project upwards. The basal joint of tha 
antenna is broad and sloping outwards. The second joint of 
the peduncle (although not compressed) is large and promi- 
nent. The external maxillipeds resemble those of Hahniiis. 
The pleon segments in the female are free. The dactyli of 
the ambulatory legs are without spinules.
