Catalogue of Decapod Crustacea in the Indian Museum. The 
prawns in his collection should: prove of almost equal value 
in the survey of the Palaemonidae and Atyidae now being 
carried out by Mr. Stanley Kemp. who two years ago succeeded 
to Mr. Wood- Mason’s original post in its present form. Perhaps 
the most interesting vests eT made with reference 
to the freshwater prawns is the discovery that a primitive 
Atyid (Xiphocaridina abit hitherto only known from 
New Zealand and certain other islands in the same region, 
Austen and now identified, after careful comparison with 
specimens from New Zealand, by Mr. Kemp. Another interest- 
ing recent discovery is that of Apus cancriformis® in the Unite 
Provinces and Kashmir. This little crustacean, which is 
known to appear, disappear and reappear in a most erratic 
manner in European countries, had not hitherto been recorded 
from India, although a closely allied form was described from 
the base of the Himalayas about forty years ago.’ Dr. J. “a 
Henderson, now Superintendent of the Madras Museum, an 
Mr. G. oan lately Assistant Professor in the Christian Col 
lege, Madra ‘have within the last few years reviewed the 
prawns of the genus Palaemon that occur in the Madras Presi- 
dency,* while Professor E. von Daday® of Budapest has des- 
cribed several interesting representatives of the lower crustacea 
from different parts of India. Another interesting discovery 
recently made is that of a freshwater representative of the 
parasitic group Rhizocephala, which are allied to the barnacles 
and like them hitherto regarded as exclusively marine. This 
animal (Sesarmaxenos) was found attached to a Eros or 
possibly anadromous crab on a hill i in the Andam 
f os Indian freshwater ‘‘ worms,’’ using t the term in its 
widest sense, we know as yet very little, but Major J. Step-
