CRUSTACEA. 287 
7. Leiolophus planissimus Herbst. 
Sixty specimens of different size from Endeh, Flores, 
among which about as many female as male individuals. 
The lateral margins of the cephalothorax are armed 
with four teeth, the extraorbital teeth being included. 
There are no small tubercles on the posterior cardiacal 
region, that should be found on that of Leiol. affinis M. B. 
from the Sandwich Islands. Seven or eight small sharp 
teeth are found on the external half of the supraorbital 
margins and three or four very small acute tubercles are 
observed on the internal margins of the antennulary cavi- 
ties, 1. e. upon the lateral margins of the front. These 
characters are presented by all the sixty specimens, as 
well by the males as by the females. 
The specimen figured by Herbst, is apparently a female. 
8. Geograpsus sp. 
A very young male from Poeloe Samaoe. 
This specimen could not be identified by me with any 
of the known species, on account of its small size, the 
cephalothorax being only 9 millim. broad; it belongs pro- 
bably to Geogr. Grayi M. E., as the meropodites of the 
ambulatory legs of Geogr. crinipes Dana from the Pacific 
Ocean are more enlarged. 
9. Sesarma Aubryi A. M. E. 
Two young specimens (7, Q) from the island of Great- 
Bastaard, near Flores. lef Q 
Greatest width of the cephalothorax: 11 millim. 10°/, millim, 
Breadth of the upper frontal margin: 44/; » 4e, > 
In these specimens the front therefore not yet measu- 
res half the width of the cephalothorax. 
The penultimate joint of the male abdomen is 3°/, millim. 
broad at its posterior margin and 1°/, millim, long.
