are oblique to the long axis of the test. Ornamentation of the interporiferous area 

 small and rather crowded, smaller and closer than that of the interradium. The 

 breadth of tliis zone is slightly more than twice that of a poriferous one. 



Antero-lateral ambulacra large, long, petaloid near the apex, open distally 

 and yet slightly tending to closure. The poriferous zones are sunken, broader than 

 those of the anterior ambulacrum, and have well-developed costse, each with a row of 

 granules on it. The anterior zone is short, curved, and its remote end approaches the 

 posterior, which is long and with a double curve, the outer end turning slightly back- 

 wards beyond the line of the termination of the anterior zone, which is the shortest 

 by about twelve pairs of pores. The interporiferous area is smaller and higher than 

 the poriferous zone, and it is covered with a close ornamentation. 



The ornamentation of the test is altogether larger and coarser actinally; the 

 actinal surface is tumid, but depressed centrally. The mouth is in front of the centre. 



Length 83 millim., breadth 69 millim., height 28 millim. Eelational dimen- 

 sions — length to breadth 1 : 0-83, to height 1 : 0*33. 



Locality. Kachh. Nummulitic group, west of Junagia, north of lera. Survey- 

 number C 060 A f. 



It will be observed that the dimensions coincide closely with those of E. Sindensis, 

 but the shape of the ambulacra affords a specific distinction.

The second specimen has a higher test, and it shows part of the peristome, which 

 has well-developed projecting bourrelets. It came from the same locality. 



10. EcHmoLAMPAS ViCAKYi, d'ArcMac & Haime. 



A specimen, already alluded to, of this species is in the collection from Kachh, and 

 it shows the large well-developed peristome characteristic of the type preserved in the 

 Museum of the Geological Society. The posterior part is preserved, and shows the 

 elliptical periproct submarginal and close to the edge. The posterior ambulacra tend 

 to close near the margin, in consequence of the bold curve of the anterior poriferous 

 zone, which reaches far towards the margin, passing not very far in front of the shorter 

 and straight posterior zone. 



We have not figured this form, as doubtless better specimens wiU come to hand.
