 pp. 185-189 (1897), & Bd. x. pi. xxx. f. 34 (1898). 



Hah. Malacca; littoral. Two males. 



I am inclined to refer these to the above species, because in the 

 general form of the carapace and chelipedes they agree with Dr. 

 de Man's description, and more especially in the cross -markings 

 on the tubercles of the dactyl, which are very distinctive : they 

 give them an appearance which Dr. de Man describes as " treppen- 

 formig," for which I can find no English equivalent. There are, 

 however, two points in which these individuals differ from the type : 

 (a) in the number of the tubercles ; these are fewer, being 8-9 

 instead of 12-13 : (b) in the number of pectinated ridges ( = Kamm- 

 leisten, de Man) of the hand. Of these, in the larger male there 

 are four, all well-marked, the proximal one being a little shorter 

 than the distal three, which are equal in length. In the smaller, 

 however, there are only three on the left hand, i.e. counting disto- 

 proximally 1, 2, and 4: 3 being merely represented by a short 

 line of granules projecting only a little way between the 

 external terminations of 2 and 4. In the right hand, 3 is more 

 developed as a pectinated ridge extending half-way to the internal 

 upper margin, and 4 is correspondingly reduced to a granular 

 line, becoming externally fainter. Allowing, then, for this varia- 

 bility, and also for the fact that the actual number of tubercles on 

 the dactyl is also slightly variable in the species of Sesarma, I have 

 not thought it advisable to separate these two individuals from 

 S. calypso. Colour of hands orange-red.
