OF SOUTHERN INDIA.

T ranee is more depressed, retiform, the areolm of the interambulaera larger, and 
the miliary part mueh smaller ; the spines also appear to have slightly longer neeks. 
liether these differenees indieate an individual or a spceilic distinction, I am unfor- 
tunately not in a position to say for want of materials. 
Locality. — Oiapaudy, in a marly, slightly oolitic rock. 
Formation . — Arrialoor group. 
C. sceptrifera is one of the most characteristic and widely-spread fossils of tlie 
uppermost cretaceous deposits, Seuouieu, IVhite Chalk, Oberer Flmner, etc. 
CiUARis n. sp. PL All, Fig. 37. 
A single interamhulacral plate, evidently one belonging to the upper part of the 
test, dilfers by its prominent, moderately sized, tubercle, comparatively large areola, 
surrounded by slightly 2ii’ominent mammillary granules, alternating wuth other 
more strongly marked ones, and by the great size of the other granules, all of which 
are radiately elongated, from all known species of Cidaris of which I have been able 
to consult descriptions or flgiu’cs. 
Locality. — South-east of Arrialoor, out of a light grey sandstone. 
Formation . — Arrialoor group. 
Order. ASTEROIDEA. 
The starfishes differ from the other Echinodermata by the depressed, rounded 
or pentagonal form of their body, the angles being prolonged into five single or 
branched arms, on which the ambulacral grooves, originating at the mouth, are 
continued ; they arc lined on either edge Avith one or more series of 2Aedicles wdiich 
constitute the 2R’iucipal locomotive organs. The mouth lies on the lower side and is 
central. 
Tlie tAvo 2n'inci2)al suborders arc the OmivuiDM and the Asteriitj/e, which by some 
authors arc regarded as two different orders. Although, on account of the difficul- 
ties in 2Arcscrvation, they are not so common in a fossil state as are other Echinoder- 
mata, their representatives occur already in silurian rocks, but the larger number 
of them, both of genera and species, belongs to the 2iresent e2)och. 
We unfortunately do not possess even a fragment of the whole order from the 
South Indian cretaceous de2)osits. Prof. F orbes, hoAvever, reports upon a fragmentary 
specimen of an Oiffiiurid fossil from Verdachellum, out of Mr. Cunliffe’s collection. 
As I am unable to add any information regarding the species, I Avill, for the sake of 
com2ffeteness, transcribe Prof. Forbes’ note.
