These are all covered, on the back of the carapace, with dense tufts of hair. Dim. d 34 x 32-5. d 19 x 16. $ 36-5 x 33. $ 32 x 29. 84. SESARMA CALYPSO de Man. Sesarma (Parasesarma) calypso, de Man, Zoolog. Jahrb. Bd. ix. pp. 185-189 (1897), & Bd. x. pi. xxx. f. 34 (1898). Hab. Malacca; littoral. Two males. I am inclined to refer these to the above species, because in tbe general form of the carapace aud 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 ( = Kainm-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-proxirnally 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 variability, 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. Dim. d 17x13. d 16-5x12-5. 85. SESARMA ONYCHOPHORA de Mau. Sesarma (Perisesarma) onychophora, de Man, Zoolog. Jahrb.
