the Scorpions of India. 73 



Scorpio crrsarj C. Koch. 



TliPS|:ocimon ticketed " Ceylon " in tlie ]\ruseum collection, 

 which I identified in the ' Bombay Journal,' vol, viii., as S.ca'sar, 

 proves to be an aberrant example of *S'. africanus (Linn.). 

 The locality Ceylon, which I have very little doubt is erro- 

 neous, ])ut me off the track of its accurate determination. 



Two other scorpions in the collection, which I now refer 

 to S. ccesor, arc nearly related to S. megacephalus^ but may 

 be recognized from it by having the hand wider, more convex 

 above, and with its inner edge much more strongly convex ; 

 moreover, the keels of the tail are strongly denticulate, very 

 much as in S. hengahnsis. 



The two examples give the following measurements in 

 millimetres : — 



(J (in alcohol). — Total length about 125, of carapace 18, 

 of tail 63; width of brachium 7*5, of manus 17'8; length of 

 hand-back 13, of movable digit 19. 



? (dry). — Total length 91 ^ of carapace 15*5, of tail 52; 

 width of brachium 6, of manus 15 ; length of hand-back 10*5, 

 of movable digit 15. 



Judging from these two specimens, both of which are from 

 Ceylon, the sexes do not differ appreciably with regard to 

 length of tail or of palpi.

This species attains a far larger size than I suspected when 

 describing it. Since that time the Museum has received 

 several examples from India (Miss Emma Phipson's collec- 

 tion) and one from the Bombay Presidency presented by 

 Mr. N. Masterman. The largest of these examples (a male) 

 measures about 140 millim., of which the carapace is 20 and 

 the tail 72, while the largest female measures (with the abdo- 

 men distended) about 138 millim., the carapace being 19 and 

 the tail 63 ; in the male the palpi are very long, measuring 

 about 90 millim., of which the brachium is 22"5, the hand- 

 back 19, and the movable digit 21, while the width of the 

 hand is 15'5. In the female the palp is only 67, the brachium 

 being 15, the hand-back 14*2, and the movable digit 19, while 

 the width of the hand is 16, 



This species may be readily distinguished from S. mega- 

 cephalus of C. Koch by having the upper surface of the hand 

 considerably more convex, the area above the keel being 

 vertical, the inner border also more convex, and the posterior
