288 CRUSTACEA. 
10. Sesarma sp. 
One young male specimen from the island of Great- 
Bastaard, near Flores. 
It cannot be identified with certainty, but it is closely 
allied to Ses. angustifrons A. M. EH. from the Pacific 
Ocean. This species also presents a great resemblance to 
Ses. Weberi de Man from Flores, but I cannot see a trace 
of the characteristic transverse ridges that are found on 
the mobile finger of the anterior legs of the latter form, 
so that it may not be referred to Ses. Weberi. 
The cephalothorax is 9 millim. long. 
11. Remipes denticulatifrons White. 
Confer: de Man, Decapoden des Indischen Archipels, 
in: Max Weber, Zoologische Ergebnisse einer Reise in 
Niederländisch Ost-Indien, Bd. II, 1892, p. 351. 
Four specimens from Endeh, Flores. 
The cephalothorax of the two largest is 24 millim. long. 
In this species the fine interrupted transverse lines on the 
upper surface of the cephalothorax are very numerous and 
crowded, for the most part short and all are crenulated 
in zigzag-lines. The shallow pits bordered with tufts of 
short hairs, that form a linear series on the lateral mar- 
gins of the carapace, are numerous and close. The lateral 
lobes of the front are triangular, spiniform and project 
beyond the level of the median lobes. The terminal joints 
finally of the second and third pair of legs are strongly 
falcate. 
12. Petrolisthes inermis Heller. 
Plate 7, fig. 1. 
One single young male specimen, collected together 
with the following species at Endeh, Flores, ought very 
likely to be referred to the above-mentioned Petrolisthes.
