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



2. Pecten obliquus, Sowerby. 



In the Verdachellum collection are specimens not to be distinguished from the 

 lower greensand Pecten obliquus of the beds in the Isle of Wight. 



3. Pecten orbicularis, Sowerby ? 



A fragment not sufficiently perfect to admit of certain identification. 

 Locality, Verdachellum. 



4. Pecten virgatus, Nilsson. PL XV. fig. 22. 



Two very perfect valves, differing in no essential particulars from the European 

 greensand form. 



Locality, Trinchinopoly. 



5. Pecten verdachellensis, sp. nov. PI. XIV. fig. 5. 



P. testa orbiculari, depressa, longitudinaliter costata, costis numerosissimis, tenuibus, squa- 

 mosis, alternatis majoribus ; auriculis agqualibus radiato-costatis. 

 Length and breadth ly^^ inch. 



In most of the specimens the scales of the rays of this very distinct Pecten are 

 worn away, so that the latter appear as if crossed by numerous thread-like striae. 

 The cast is more or less smooth, but exhibits traces of the ribs and scales towards 

 the margin. 



Locality, Verdachellum. 



Genus Lima, Brugui^re. 

 L Lima obli qui- striata, sp. nov. PI. XVIII. fig. 13. 



L. testa obliqua, ovata, convexa, longitudinaliter costata. transverse (obsolete) striata ; striis 

 lateralibus obliquis. 



Length Oj^ inch. Breadth O/g inch. 



Resembling Lima undata in outline. Remarkable for having the numerous 

 longitudinal ribs crossed by transverse strise which become oblique towards the 

 sides. It is nearly allied to Lima granulata from the greensand of Westphalia, 

 figured by Goldfuss, pi. 104. fig. 5. 



Locality, Verdachellum. 



Genus Spondylus, Linnaeus. 



1. Spondylus subsquamosus, sp. nov. Pi, XVIII. fig. 1. 



S. testa obliqua, suborbiculari, valva dextra complanata, affixa, longitudinaliter striata et 

 transverse plicata ; valva sinistra convexa, sulcata, sulcis numerosissimis regularibus longitudi- 

 nalibus, costis elevatis acutis, ad marginem squamis paucis.
