margin, the two sometimes being joined together to form an N-shaped figure. In the 
largest male the carapace was olivaceous green, marbled and streaked and without 
definite markings. The chelipedes in this specimen were blackish externally and pale 
olive internally, the fingers being black with white tips. In smaller individuals the 
chelipedes were olive, with white fingers and with two scarlet bars on the chela. 
The first of these was situated at the proximal end of the palm and the second at the 
base of the fingers. The walking legs bore alternate pale and dark bars. 
Palaemon neglectiis has hitherto been recorded from King I. and Elphinstone I. in 
the Mergui Archipelago and from DeH on the E. coast of Sumatra.

A large number of specimens collected in Java by the late Dr. W. C. Hossack be- 
long to this variable species; they agree with de Man's description and with three 
Javanese specimens determined by de Man and preserved in the Indian Museum. 
About sixty specimens, including one ovigerous female, were obtained in the 
Government Quinine Gardens at Tijnproean, at an altitude of 5600 ft., while two 
others were found at Garoet at an altitude of about 3000 ft. The ovigerous female is 
45 mm. in total length and the largest male 59 mm. 
The species is known from Java, Su:natra and Borneo and on the continent of 
Asia from Aring in Kelantan and the Belimbing River.

Fifteen specimens were obtained by Dr. Annandale in the Patani River, below the 
town of Patani in the Siamese Malay States. The series agrees very well with de 
Man's account, but the rostrum is longer than in the large male that he described in 
detail, reaching to, or even a little beyond the apex of the scale. There are from 15 
to 18 teeth on the upper border of the rostrum ' of which 3 or 4 (usually 4) are situated 
on the carapace behind the orbit. Oxi the lower margin there are 3 or 4 teeth, 
usually 4. 
The specimens are small, the largest being only about 45 mm. in length ; the 
chelipedes in several individuals are equal and in no case do they reach beyond the 
antennal scale by more than the length of the chela. In their form, however, and in 
the dentition of the fingers they are in precise agreement with de Man's description. 
' Of fifteen specimens two have 15 dorsal teeth, six have 16, five have 17 and two have 18.
