carapace 18.5; and also, judging by Koch’s figure, the type speci- 
men which, with its large number of pectinal teeth, is probably a 
male, shows similar differences from the specimens of cavzmanus. 
Scorpio gregorit, POC. 
Ann. Mag. Nat. Hist. (6), xvii. p. 432, Pl. XVIII., fig. 3 (1896). 
An adult 2 example, without special locality; but since Sc. 
Gregorit is a more southerly type than Sc. Swzthiz, and has been 
recorded from Tzavo, Kinani, and Tanganyika, it seems probable 
that this example was obtained on the homeward march. 
This specimen agrees with those obtained by Dr. Gregory in all 
specific features; it is interesting to observe, however, that there 
are only 15-16 pectinal teeth. 
Scorpio smithit, sp. n. 
? closely allied to Sc. phzllipsiz,’ Poc., from Dooloob in Somali- 
land, from which apparently it differs only in the size and sculp- 
turing of the hand. 
In phillipsit the upper surface of this organ is covered with 
rounded or elongate and often fusing tubercles, which show a tend- 
ency towards dying away upon the posterior lobe of the hand, 
the edge of which is smooth; but in Sc. swzthzz the upper sur- 
face of the hand is covered with definitely shaped conical or acute 
tubercles, which show no tendency to fusion, and do not disappear 
upon the posterior lobe, the margin of which is denticulate right 
up to the articular socket of the brachium. The inner border of 
the hand, too, is more convexly produced from the base of the 
immovable digit, which imparts a greater width to the organ and 
makes it exceed the length of the carapace. Width of vesicle equal 
to width of 4th segment, height of it less than width of 5th. 
Number of pectinal teeth, 18-19. 
Measurements in millimetres: Total length, 100; length of tail, 
53; of carapace, 15; length of hand-back, 9.5; of movable digit, 
bS; width of hand, 1555. oo, Uurfa. 
& A male example closely resembling the ? in all characters 
except those attributable to sex has unfortunately had the date on 
its label obliterated. It cannot consequently be assigned to any 
locality, though from its close resemblance to the ? it seems not
