Introduction. 



Some years ago I received from Prof. J, R. Hendersoist 

 of the Christian College, Madras, a small collection of Phyl- 

 lopoda, procm'ed by him from the surrounding parts of India, 

 and kindly placed in my hands for determination and de- 

 scription. As it has been my purpose to render the exotic 

 forms of this interesting group more easily determinable 

 than is possible from the generally very imperfect descrip- 

 tions given by earlier authors, I have subjected the forms 

 contained in the above-mentioned collection to a close exa- 

 mination, and propose in the present paper to give an ac- 

 count of the species, accompanied by carefully drawn figures. 

 There are in all 6 species, one very beautiful Streptocephaliis, 

 the others belonging to the division Conchostraca, or bivalve 

 Phyllopoda. I have been enabled to determine 2 of the 

 species with full certainty, whereas it has been im- 

 possible for me to identify any of the remaining 4 species
