margin, the two sometimes being joined together to form an N-shaped figure. In the 

 largest male the carapace was oUvaceous 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 neglecfus has hitherto been recorded from King I. and Elphinstone I. in 

 the Mergui Archipelago and from Deli 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 spacies ; they agree with de Man's description and with three 

 Javanese spscimens determined by de Man and preserved in the Indian Museum. 



About sixty specimens, including one ovigerous female, were obtained in the 

 Government Qainine 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. 



Tlie species is known from Java, Sumatra 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. On 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 i6, five have 17 and two have 18.
