OE SOUTHERN INDIA. 
General remarks on the distrirktion oe the Echinodermata in the 
S oETH Indian cretaceous deposits. 
The conclusions which can he drawn from the examination of the Echinocler- 
mata coincide well with the results obtained from that of the different classes of 
Mollusca occurring in the above-mentioned deposits. 
Of the five different orders of the class tlmee occur in South India. Our knoAv- 
ledge, however, of the single imperfect specimen of Ophiura, described by Eorbes, 
is entirely insufficient, and as the geological position of tlie species is also not knoivn, 
the whole of the Asteroidea must he left out from the present consideration regarding 
the age of the rocks. Of the two other orders the Echinoidea arc represented hy 
38 species, hut of these again four remain doubtful as regards their geological age. 
The Crinoidea have only two, or possibly three, species, belonging to Pentacrinm 
and Ilarmpites, the latter being an exclusively cretaceous genus. The local and 
geological distribution of the different species ivill be more readily understood from 
the following list : — ■
