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 

 hrachydadyla, 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- 

 chester, from the Singapore Botanical Gardens and of Sesarma andersoni, de Man, 

 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 I^angkawi 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 v/ith certain groups of species concerning which our knowledge was more 

 than ordinarily deficient, I have found it advantageous to work through portions of
