CRUSTACEA. 285 
A single young male specimen from Poeloe Samaoe. 
I have described (1. c.) some specimens of Leptodius from ° 
the Bay of Batavia under the name of Lept. crassimanus 
A. M, E , most of which presented the peculiar shape of 
the front characteristic of this species, but some of which 
more resembled Lept. exaratus M. H., as regards the shape 
of the front. The specimen from Poeloe Samaoe now fully 
agrees with the last-named specimens, the front present- 
ing the same form as in Lept. exaratus. The antero-lateral 
margins, however, are armed with six teeth, the lobes of 
the upper surface are rather much prominent and finely 
granulate near the antero-lateral margins and are more- 
over somewhat rugose on the anterior half of 
the upper surface. The cephalothorax and the cheli- 
pedes are marked on the same manner with the characte- 
ristic orange-coloured spots. 
For the rest this specimen perhaps may be referred with 
the same right to Lept. sanguineus M. E. 
The cephalothorax is 15 millim. broad and 9}/, mil- 
lim. long.

One young male specimen from Poeloe Samaoe. — 
The fourth antero-lateral tooth is considerably smaller 
than the other teeth, so this specimen must be referred 
to the variety Stimpsonit A. M. Edw. The abdomen does 
not present the form that I have figured, 1. ce. fig. 9, but 
more resembles the figure published by A. Milne Edwards 
(Archives du Muséum, T. X, Pl. XXXVI, fig. la), the 
lateral margins of the penultimate joint not bulging out 
anteriorly and being rather little convex. 
The cephalothorax is 20'/, millim. broad.
