Prof. Henderson, to show the identity of the Australian and 

 Indian forms. 



Occurrenc e. — A few specimens of this interesting form 

 are in the collection, having been taken from pipe water 

 of the city of Madras. Prof. Henderson informs me, that at 

 certain seasons this form occurs here in great abundance. 



Distribution. — The specimens originally examined by 

 Baird were taken at Nagpur, and Prof. Brady has subse- 

 quently recorded it from Colombo, Ceylon. I have myself 

 been enabled to state its occurrence also in Australia, the 

 mud from which the specimens were raised having been 

 taken from the Crescent Lake, North Queensland. According 

 to Dr. Weltner, this form has also been found in Celebes, 

 and, moreover, in East Africa by Dr. Stuhlmann, and in 

 Brazil by Dr. Ehrenreich. This Phyllopod seems accordingly 

 to have quite an extraordinarily wide geographical distribu- 

 tion, though perhaps some doubt may arise as to the spe- 

 cific identity of the East African and Brazilian forms, of 

 which hitherto no descriptions or figures have been published.

 following species have been recorded by. earlier authors as 

 occurring in India:
