OF KACHH AND KATTYWAE. 91 



The absence of Echinolampince from the collection is remarkable. Euspatangus 

 patellaris, d'Archiac, is found in Kattywar as well as in the Kachh Miocene. 



The commonest fossil in Kattywar is Schizaster Granti, nobis, which had no 

 satisfactory geological horizon given to it in Kachh. Schizaster Granti, nobis, is a 

 beautiful form, with sharp-pointed antero-lateral petals flaring outwards and a low keel 

 on the posterior interradium ; it has a transverse concavity posteriorly, so that the test 

 above the periproct projects backwards and the hinder part of the plastron also. The 

 periproct is visible from the actinal view, although it is high up posteriorly. The 

 granular ornamentation of the posterolateral ambulacra on either side of the actinal 

 plastron is very characteristic. The species is very distinct, and yet it has been 

 mistaken for Schizaster Baluchistanensis. It is the common Schizaster of the Miocene 

 of Western India. 



APPENDIX. 



The following species was accidentally omitted from the Nummulitic fauna of 

 Kachh. It is interesting on account of its alliance with a Sindian Nummulitic form. 



Genus SISMONDIA, Lesor, 1857. 

 1. SiSMONDiA POLYMOEPHA, var. SUFFLATA, Duncan & Sladen. 



This form constitutes a well-marked variety of a species we are about to describe 

 from the Khirthar series of strata in Sind. It is characterized by a generally much 

 smaller habit, by a comparatively thicker margin, and especially by the low, but 

 decided, convexity of the abactinal surface. The same great variability in the marginal 

 contour is noticed, although the more elongate and less angular forms appear to prevail. 

 The characteristic tumidity of the postero-lateral petals is also present, • The petals 

 terminate at a greater distance from the margin than in the type form, and are very 

 short for the genus. 



The length of one of the largest specimens is 7-5 millim., and the breadth 6-5 

 millim. 



Locality. From the Nummulitic series of strata of Kachh. Three or four miles 

 north -north-east of Pipur. Survey-number C 039.
