ZOOPHYTA. 



Helianthoida, 

 Genus Fungia, Lamarck. 



1. Fungia Jilamentosa, sp. nov. PI. XIX. fig. 11. 



F. testa semiglobosa, circular!, supra elevata, convex^, depressione centrali elongata, parum 

 profunda; lamellis numerosissimis, tenuissimis, regularibus, aequalibus, simplicibus; basi con- 

 cava, laevigata, radiato-striata ; striis numerosissimis, simplicibus, aequalibus, lineis distantibus 

 incrementi vix interruptis ; margine acuto. 



Diameter 0/^ inch. Height 0^*^ inch. 



The smoothness of the excavated base and extreme regularity of the very fine 

 lamellae distinguish this Fungia from most described forms. It belongs to the 

 group usually referred to Cyclolites. The Cyclolites discoidea of Blainville (a 

 greensand fossil) is its nearest ally. C. elliptica of Lamarck, a nummulitic lime- 

 stone species, is also nearly allied to it. 



Locality, Pondicherry. 



Genus Turbinolia, Lamarck. 



1. Turbinolia arcotensis, sp. nov. PI. XIX. fig. 9. a, b. 



T. testa cyhndrica, conica, elongata, disco excavato, lamellis (30) fortibus radiato ; lateribus 

 undulatis, striatis, striis tenuibus, confertis, regularibus, aequalibus. 

 Diameter of disc 0~ inch. Entire length (or height) ly^^ inch. 



A conical species, usually shghtly bent, with finely and regularly striated sides, 

 and a star of many strong prominent lamellae. The specimens are rarely well- 

 preserved. The species is gregarious. It approaches nearly several cretaceous 

 and also some tertiary forms. 



Locality, Pondicherry. 



Genus Cladacora, Ehrenberg. 



In the Pondicherry collection are fragments of a coral apparently belonging to 

 this genus. They are cylindrical, slightly undulated, and closely and regularly 

 longitudinally striated. (Plate XIX. fig. 10.) In the absence of better specimens 

 I abstain from giving any specific appellation. 



Bryozoa. 



Traces of incrusting corals of this order, probably belonging to Flustra and 

 Lepralia, are seen on several shells in the collection, but not sufficiently perfect to 

 warrant definition.
