5. Differs from all other species of the genus in that the vesicle 
has a double row of granules inferiorly ; supero-anterior crest 
of humerus strong ; upper surface of hand only slightly 
convex ; sides of fifth caudal segment without granules ; 
carapace finely granular throughout except anteriorly. C. inl ermedius Hewitt.

The type of this species was stated to have come from Tette ; we have 
a large series from Serowe (S. Blackbeard) which, according to Prof. 
Kraepelin, who has examined Peter's type, should be referred to this species. 
However, it is very improbable that the form which occurs in the neighbour- 
hood of Tette can be identical with that from Serowe. The characters of 
the Serowe specimens are as follows : 
Anterior margin of carapace quite straight ; terminal tooth of superior 
caudal crests only slightly enlarged, not subspiniform, except sometimes 
that of the third segment in males ; superior crests of caudal segments II 
and III only very feebly toothed, distinctly so in IV and V ; sides of 
vesicle finely granular and outer surfaces of patellae finely granulated 
throughout ; upper surface of hand slightly convex, and in the male there 
are some fairly strong denticulations just below the inner edge ; the lobe 
at the base of the movable digit low and broad in the male, but higher and 
stronger in the female ; tergites of male moderately finely shagreened, of 
female quite without granules or with the finest dust-like granulation at 
the sides ; pectinal teeth of male 23-28, of female 19-22 (the types have 
male 22-23, female 18-20) ; fifth caudal segment of male distinctly longer 
than the hand-back. Other important characters are contained in the 
following measurements, based on typical adult specimens from Serowe : 
Total length, M. 166, P. 152 ; length of carapace, M. 16, P. 18-5 ; breadth 
of carapace, M. 16-25, P. 19-4; length of hand, M. 30-5, P. 35-5; breadth 
of hand, M. 9-8, P. 12 ; width of upper surface of humerus including 
granules, P. 6-4; length of last sternite, M. 11, P. 12-5; breadth of last 
sternite, M. 13, P. 16; length of first caudal segment, M. 16*5, P. 11*5; 
width of same, M. 3, P. 3-5 ; height of same posteriorly, M. 4*25, P. 4*4; 
length of second caudal segment, M. 21, P. 15*2 ; length of third caudal 
segment, M. 22, P. 15-5 ; of fourth caudal segment, M. 23-5, P. 17-5 ; of 
fifth caudal segment, M. 20, P. 16 ; of vesicle, M. 9-2, P. 10*3 ; breadth of 
vesicle, M. 2-9, P. 3-5 ; height of vesicle, M. 3-7, P. 4. 
This Serowe form is probably the same as H. hetschuanicus Penth. (26),
