Of the six species of Echinoid which are described by 

 Agassiz, in his ' Revision of the Echini ' as being character- 

 istic of his Indo-African Region, which includes the Madras 

 coast, five, viz., Echinodiscus aurifus and biforis, Salmacis 

 sulcata and bicolor, and Echinolampus oinformis, are very 

 abundant in the Gulf of Manaar. But I have not as yet 

 found the sixth species, Echinodiscus Icevis. 



The fossil Echinodermata, as recorded in the ' Palaeonto- 

 logia indioa' from the cretaceous deposits in South India, 

 are represented by two or three species of Crinoidea {Penta- 

 crinus and Marsupifes), a single species of Asteroidea (Ophiura ? 

 cunliffei), and thirty-eight species of Echinojdea, of which 

 the genera Cidaris and Hemiaster are most largely repre- 

 sented.
