XVI. NOTES ON ASIATIC SPECIES OF 



CRUSTACEA ANOSTRACA IN 



THE INDIAN MUSEUM. 



By STANI.EY Kemp, B.A., Assistant Siiperintendent, Indian 



Museum. 



The publication of Prof, E. von Daday's valuable monograph 

 on the Branchiopoda Anostraca ' has enabled me to determine the 

 unnamed specimens of this group in the Indian Museum without 

 difficulty. Prof, von Daday was kind enough to examine the major- 

 ity of species in the collection at the time when he was working 

 at the group and the number of specimens which have since 

 accumulated is not large. 



No additions to the comparatively small number of species 

 found in India were included in the material awaiting identifica- 

 tion ; but an enumeration of the forms at present known from India 

 and the countries adjacent to it, with such details of their occur- 

 rence as are known, will perhaps be of some assistance to those 

 interested in the freshwater Crustacea of this region. 



Owing to an unfortunate mistake the real types of Alcock's 

 Branchipus bobrinskii were not sent to von Daday when he was pre- 

 paring his monograph. The species is here identified with Chiro- 

 ccphaius altaicus, von Daday. 



Six species of Anostraca, belonging to five genera, are now 

 known from India, from the countries abutting on its northern 

 frontier and from Ceylon.

This species is known from Hungary and Russia and extends 

 eastwards as far as the Pamirs, Tibet and Mongolia. The Tibetan 

 specimens, which are preserved in the Indian Museum, were pre- 

 sented by Capt. R. E. lyloyd who obtained them in August, 1904. 

 They were taken in a large muddy pond, evidently not permanent 

 in nature, at the foot of Gyantse fort at an elevation of about 

 13,000 feet. Though they were found in August von Daday 

 refers these specimens to the seasonal phase called ' forma vernalis ' 

 which differs from the ' forma aestivalis ' only in its larger size.
