back, a somewhat convex ventral face, and apparently a different 

 number of lucid spots, and as they want also the longitudinal 

 wrinkles of the ventral surface, they must be at least varietally 

 distinct. 



Dr. Carter has recognized in some fossil CypHdes from Bombay 

 the marginal appendix, or " lunate fossa," of the anterior extremity. 



3. Cypris Hislopi, spec. nov. PI. X. fig. 71. 



This has a somewhat triangular carapace, much compressed to- 

 wards each extremity, and is not unlike C. celtica, Baird, but is 

 more obtuse at the hinder end. It is 1th inch long, and T V,th high at 

 the anterior hinge, which is more acute in the old individuals than 

 in the young. The surface is brownish, with delicate wrinkly reticu- 

 lations, passing into punctation. 



4. Cypris Hunteri, spec. nov. PI. X. fig. 72. 



This is a rarer form. It is of the same size as C. Hislopi, but 

 differs materially in form, being nearly oblong, subeylindrical, thick, 

 and bulky ; whilst the latter is subtriangular and comparatively flat. 

 1 have not seen a well-preserved exterior. Small specimens less than 

 -jLth inch occur. 



5. Cypris strangulata, spec. nov. Plate X. fig. 73. 



This (Jypris is somewhat oblong in profile, but rounded behind, 

 and obliquely rounded in front, irregularly ovate seen from above, 

 triangular on end-view, and constricted in the anterior region of 

 each valve by an oblique linear depression, commencing behind the 

 anterior hinge, and curving forwards and downwards. The cara- 

 paces vary considerably in the gibbosity of the valves. Ordinary 

 specimens are -.^tli inch long, -j-'-^th high, and -^-th thick. 



(i. In a whitish siliceous rock from Chickni. presenting innume- 

 rable cavities left by decomposed Cyprides and other minute fossils, 

 we have numerous Entomostracous valves, mostly much flattened, 

 some of which are referable to C. cylindrical btrt the majority pre- 

 sent such pmtcan proportions, varying from orbicular to oval and 

 oblong, as we trace them from size to size, that I hesitate to separate 

 them specifically. They all appear to have partial marginal rims. 

 and to lie smooth. One of Dr. Baird's figures of Cypris dentato- 

 marginata is nol unlike some of these specimens from chickni. 



7. Prom Katera (from an estuarine deposit) we have a few very 

 small specimens of a subeylindrical form, which are relatively shorter 

 ami thicker than C. cylindrica, and have a somewhat angulated 

 hinge-line. These may belong to the Cytherida. 



8. In a piece of rock from Pungacfi their is a trace of an Knto- 

 mostracous carapace, possibly a Cythere. 



0. Some drawings of Entomostracous carapaces, from the Inter- 

 trappeao beds of the Narbadda Territory, have been shown me by 

 the Kev. s. Bislop. The drawings have been made from specimens 

 collected by the Geological Burveyof India. I can only suggest that 

 probably Cypris subghbosa and ('. ir>si<>i>i are among the specimens 

 referred to.
