XXXV. CRUSTACEA AMPHIPODA. 



By Walter M, Tattersall, D.Sc, Keeper uj the Manchester 



Museum. 



(Plate xxviii). 



The Amphipoda collected by Mr. vStanley W. Kemp on the Abor 

 expedition may all be referred to a single species, which, after 

 much hesitation, I have described as new to science. They are of 

 further mterest inasmuch as they are the first semi-terrestrial Am- 

 phipoda which have ever been collected in the Indian Empire, to 

 my knowledge. The species shows very close affinity with those 

 described by Weber from Java and other islands of the Dutch 

 East Indies and in particular, with Orchestia parvispinosa from Java. 



I desire to express my thanks to Dr. Aimandale and Mr. 

 Kemp for the privilege of examining and describing these speci- 

 mens.
