such specimens they are a little more elongated, being pre- 
cisely twice as long as broad, and the fingers are a little longer 
in proportion to the length of the palm; in other respects the 
hands of these male specimens perfectly agree with those of the 
type. 
The hands of the female are smaller than those of the male, 
and closely resemble those of the foregoing variety. The hands 
of the female are a little more than twice as long as high, and 
the fingers are a little longer in proportion to the palm than in 
the male ; otherwise they present the same structure. 
The ambulatory legs are similar to those of S. intermedia, the 
joints being enlarged, whereas in S. s¢nensis they are much more 
slender. Thus the meropodites of the first pair are not quite 
twice as long as broad, the proportion of the length of these 
joints to their breadth (near the distal end) being as 11:6. 
The other joints also completely resemble those of S. intermedia. 
The dactylopodites are somewhat spinulose and hairy along their 
inner (= posterior) margins.

Sesarma Edwards is evidently a common species. It is most 
closely allied to S. intermedia, but may be recognized by the » 
enlarged abdomen of the male, and by the structure of the 
chelipedes, the wrist being armed with a small, acute, depressed 
tooth at the internal angle, and the inner surface of the palm 
being not armed with a transverse granular crest.

The collection contains eight specimens (5¢, 32) of a 
Sesarma collected on the mangrove-swamps of Zediwon, which I 
regard as a variety of the preceding species. These specimens 
differ from the type specimens of S. Hdwardsi, above des¢ribed, 
in the following characters. The front is a little larger, the 
proportion of the distance between the extraorbital teeth to the
