Prof. E. Forbes on Fossil Invertebrata from Southern India. 141 



by M. Nyst under the name of Corhula granulata. The Corbula cequivalvis of 

 Goldfuss, a fossil from the greensand of Westphalia, also belongs to this genus and 

 is nearly aUied to the Pondicherry species. 



1. Poromya glohulosa, sp. nov. PI. XVII. fig. 6. 



P. testa inflata, suborbiculari, subinaequilaterali, antice subsinuata, polita, laevigata, sub lente 

 punctis minutissimis numerosis in seriebus obliquis dispositis ornata ; umbonibus tumidis, 

 incurvatis. 



Length 0/^ inch. Breadth Of inch. Thickness of united valves Oi inch. 



Shell much-inflated, almost globular, but slightly produced and compressed at 

 one extremity. The surface appears smooth and polished to the naked eye, but is 

 really, as may be seen by using the lens, minutely and regularly punctate, the 

 punctations numerous and arranged in oblique lines. This character is lost when 

 the shell is worn, as the punctations do not perforate it. The beaks are turned 

 towards the shorter end, and there is an appearance of a cordate lunule. 



Locality, Pondicherry. 



2. Poromya lata, sp. nov. PI. XV. fig. 14, 



P. testa tenui, lata, convexa, Isevi, (sub lente radiato-punctata, punctis distantibus,) sub- 

 inaequllaterali, extremitatibus rotundatis, postico subrostrato. 

 Length O^q inch. Breadth 1 inch. 



An oblong very thin shell, slightly produced at one end and there somewhat 

 depressed. The surface is smooth to the eye, but under the lens is seen to be 

 marked by regular radiating lines of distant granuliferous punctations. 



Locality, Trinchinopoly. 



Genus Corbula, Brugui^re. 

 1. Corbula striatuloides, sp. nov. PI, XVIII. fig. 14. 



C. testa ovat&, subcompressa, incrassata, sulcato-striata, rostrata, rostro. carinata. 

 Length Oy^g inch. 



A small, ovate, thick, transversely-furrowed shell with a more or less carinated 

 beak. It is nearly allied to the British lower greensand Corbula striatula, but is 

 more compressed. 



Locality, Verdachellum. 



Genus Solecurtus, De Blainville. 

 1. Solecurtus obscurus, sp, nov. PI. XVII. fig. 3. 



S. testa transverse striata, valde inaequilaterali, elongata, compressa, extremitatibus rotun- 

 datis, umbonibus obtusissimis.
