OF KACHH AND KATTYWAR. 31 



Length of specimens 90 and 83 millim. Eelation of length to breadth 1 : 0-966 

 and 1 : 0-987 ; and of length to height 1 : 0-488 and 1 : 0-47. 



Locality. Kachh. One mile east of Goir, near Narainsir. Nummulitic series. 

 Survey-number C 043 B. 



The specimen measuring 83 millim. in length (Survey-number C 043 f B) is of 

 course smaller than the type, and its peristome is more elongate transversely and less 

 pen tagonal.

8. ECHINOLAMPAS, sp. 



Two much injured specimens of an Echinolampas, with a circular marginal contour, 

 are amongst the collection from Kachh, and they do not belong to the species just 

 described. They are indeterminable, but they approach the discus type more than the 

 perfect form. They diiFer from it in the breadth and flatness of their interporiferous 

 zones and^smallness of their poriferous zones, which are unequal except in the odd 

 ambulacrum. 



Locality. Kachh. Nummulitic series. One mile east of Goir, near Narainsir. 

 Survey-numbers C 043 B and C 043 f B. 



There are two species of Echinolampas described by d'Archiac and Haime, and 

 figured in their plate xiv. Figures 2 a, 2 b, 4l a, and 4 b refer to Uchinolampas Sindensis 

 and- JS. Vicaryi respectively. The types of the species in the Museum of the Geological 

 Society of London are so defective that no palaeontologist would now consider it 

 advisable to found species on them. They are elongate and depressed forms ; and as 

 there are specimens of corresponding shape in the Sind and Kachh Tertiaries, more or 

 less well preserved, it is of importance to decide upon their greater or less similarity to 

 the types described by the authors of ' Les Animaux Fossiles de I'lnde.' 



Echinolampas Sindensis, d'Archiac and Haime*, was founded on one specimen. 

 Its specific description is as follows: — The test is ovular, very elongate and flat, 

 with a rounded contour, the tuberosities on the latero-posterior margin being insufiicient 

 to alter the oval curvature. The apical summit, slightly projecting, is situated at nearly 

 the anterior third of the long diameter. The ambulacral petals very broad, flat, toler- 

 ably long, straight,, and hardly contracted distally. The odd ambulacrum is a little 

 narrower than the others. The poriferous zones are rather broad, nearly equal in the 

 same ambulacrum, and those of the odd one are the narrowest. 



Ambulacral areas unequal ; the lateral are the broader, the posterior being a little 

 broader than the anterior.
