less completely separated from it by a distinct though irregular ridge, 

 formed by the fusion of tubercles ; the inner border of the hand 

 strongly rounded in ? and some 6 , the length of the ' hand-back ' 

 either much less than the width of the hand ( $ and some 6 ) or 

 nearly or quite equal to it (some $ ), in some $ the width of the 

 hand is equal to the length of the movable dactylus, as a rule, 

 however, it is less. 



Legs smooth, the lower edge of the femora alone being furnished 

 with a row of granules. 



Fectines furnished with from 13 to 18 teeth ; usu.ally there are 14 

 or 15, one $ alone that I have seen has 18. 



Measurement in millimetres : — $ adult. Total length about 100, of 

 cephalothorax 16 "5, of tail 55, of first two segments ,14" 5, of 5th 

 12"5, of vesicle and aculeus 11*5, width of 1st 7, of 5th 5, of 

 vesicle 5 ; length of humerus 11, of brachium 12, of hand-back 10*5, 

 of movable dactylus 16, width of hand 13*5. 



6 adult a. Total length 84, of cephalothorax 13, of tail 49, of 

 first two segments 12*3 ; length of humerus 12, of brachium 13, 

 of 'hand-back' 10*5, of movable dactylus 14, width of hand 10. 



6 adult h. Total length 101, of cephalothorax 15*2, of tail 54, of 

 humerus 13, of brachium 14, of hand-back 11, of movable dactylus 16, 

 width of hand 13. 



These measurements show how the two sexes differ with regard 

 to the length of the tail and of the segments of the palpi or 

 chelae. They also show that the hand of the $ may or may 

 not be slender in the adult. In all the males, however, that I have 

 seen the hand if it be not more slender is much flatter than in 

 the $ . Apart from these characters, however, the $ may be 

 recognised from the ? by his cleft genital operculum and much 

 longer pectinal teeth. 



I have seen 17 examples of this species. Many of these are 

 ticketed India without further locality ; the others are from Madras 

 and Malabar. Simon has recorded it from Bellary, and Mr. Thurs- 

 ton has sent specimens from Madras and Tranquebar. It thus 

 appears to be widely spread in S. India. The British Museum has 

 other examples, which are doubtfully from Eangoon and C. Koch's
