On some Indian Phyllopoda. 23 



that at first I believed them to be identical. On a closer 

 comparison, however, some well-marked differences may be 

 found, both in the form of the shell and in the structure of 

 the enclosed animal, proving that these 2 forms are in re- 

 ality specifically distinct. It is also closely allied to the 2 

 Japanese species described by Mr. Ischikava as JE. Braueri 

 and E. packardiana ; but in both these species the caudal 

 claws are much more slender and elongated, and the caudal 

 plates armed with a greater number of denticles. The above- 

 given diagnosis, together with the figures on PI. IV, will, I 

 hope, suffice for easily recognising this species, and I think 

 therefore that I may dispense with any more detailed de- 

 scription. 



Occurrence. — The specimens in the collection were 

 collected on the Stevaroy Hills, at a height of 4500 feet. 

 They were all females.

(PI. IV, figs. 8—12.) 

 Specific Characters. — Female. Shell seen laterally, 

 oval trigonal in form, with the greatest height about equalling 

 ^4 of the length, and occurring in front of the middle, dorsal 

 margin very greatly, almost gibbously vaulted in its an- 

 terior part, and sloping abruptly in front, more gradually 

 behind, ventral margin forming a perfectly even curve, an- 

 terior extremity much shorter than the posterior, both nar- 

 rowly rounded and without any angle above — ; seen dor- 

 sally, oblong oval, with the greatest width considerably ex- 

 ceeding Vs of the length, and occurring in front of the 

 middle. Valves thin and pellucid, each with about 8 lines 

 of growth, the first one defining a rather large oval dorsal 

 area. Animal. Head of a form similar to that in the pre-
