24 G. O. Sars. 



ceding species. Eyes not very large. Antennulæ compara- 

 tively small. Antennae with the anterior ramus shorter than 

 the posterior, the former (in the specimen examined) com- 

 posed of only 5, the latter of 7 articulations. Structure of 

 the legs about as in the preceding species. Caudal piece 

 likewise very similar, though having a smaller number of 

 denticles behind; terminal claws unusually short. Length of 

 shell scarcely exceeding 5 mm. 



Remarks. — In the unusually high, almost gibbose shape 

 of the shell, this form looks very unlike the preceding 

 species, and much more resembles fully grown specimens of 

 the European form Limnadia lenticularis Lin. It is, how- 

 ever, a true JEulimnadia, as is proved by the structure of the 

 enclosed animal, which is very similar to that of the pre- 

 ceding species. The form described by Mr. Eug. Simon as 

 Limnadia Chaperi, and likewise belonging to the present 

 genus, is that which, in the shape of the shell, comes nearest 

 to the form here under discussion. It is, however, of con- 

 siderably larger size, and, according to the description and 

 figures given by the above-named author, exhibits also some 

 other differences, which seem to forbid an identification of 

 the two forms. 



Occurrence. — The specimens in the collection, which 

 are all of the female sex, were taken by Mr. Slater on the 

 top of Jamala Hill Fort, South Canara. 



Fani. Cyclestheriidœ, 



Remarks. — This family is founded upon the remarkable 

 form at first described by Baird as Estheria Hislopi, which, 

 according to the recent investigations of the present author, 

 exhibits so many and important differences from all the
