A number of these species were also obtained in the Tale Sap. The most interest- 
ing are the scarce Pyxidognathus deianira, the Leander and the subspecies of Caridina 
brachydactyla, a. species that in its typical form is known only from Celebes, Flores and 
Saleyer. 
In ditches in the vicinity of the Patani river Paratelphusa germaini (Rathbun) 
was found. 
Dr. Annandale also made a small collection at Penang. Six species were obtained 
on the island, for the most part in a hill stream in the Botanical Gardens, and six at 
the mouth of the Prai river on the mainland opposite Penang ; the latter were found 
in water of considerable salinity. The species are : —

In addition there are single examples of Paratelphusa {Paratelphusa) incerta, Lan-

from Kantan in Trang. 
To my account of this extensive collection I have added a description of a very 
interesting Grapsid {Sesarma foxi) presented to the Indian Museum by Mr. B. H. 
Buxton and obtained at the unusual altitude of 2000 ft. on Langkawi I. off the west 
coast of the Malay Peninsula. Reference is also made to a Javanese collection of 
Decapods, comprising six species, kindly obtained for us by the late Dr. W. C. Hos- 
sack. All these had already been recorded from the island by Dr. J. G. de Man. 
In dealing with certain groups of species concerning which our knowledge was more 
than ordinarily deficient, I have found it advantageous to work through portions of
