tively longer than those of Jf. elegans, being scarcely shorter 
than the propodites. For example, the dactylopodites of the 
legs of the penultimate pair are in proportion to the propodites as 
47:34, but in MW. elegans as 43 : 3.

Genus SEsarma, Say.

external orbital angle, and in which the upper surface of 
the palm of the hands of the male presents no oblique, 
parallel, pectinated ridges.

Thirteen specimens (96,42) were collected in the Mergui 
district, twelve of which were captured in fresh water at Sullivan 
Island. 
Sesarma Aubryt has hitherto been found in the seas of New 
Caledonia, Duke-of-York Island, and at Amboina; it would thus 
appear to inhabit the seas of the whole Indo-Malayan Archi- 
pelago. 
Section B.—Sesarme without an epibranchial tooth behind the 
external orbital angles, and in which the upper margin of 
the paim of the anterior legs of the male bears two or more 
cblique, parallel, minutely pectinated ridges. 
So far as I am aware, six Oriental species have been described, 
presenting the characters of this section :— 
Sesarma quadrata, Fabr., from the East Indies. 
affinis, de Haan, from Japan. 
— picta, de Haan, also from Japan. 
ungulata, M.-Edw., from Celebes and the Philippines. 
erythrodactyla, Hess, from Sydney. 
aspera, Heller, from Ceylon, Madras, and the Nicobars.
