OF KACHH AND KATTYWAE. 49 



1. Cltpeaster Sowbrbyi, Duncan & Sladen. Plate XII, Fig. 11. 



The test is flat and very slightly elevated at the rosette only, the margin is barely 

 swollen, and the whole test is longer than broad ; it is truncated and indented for a 

 short space behind, rather straight at the sides, truncated at the posterior lateral 

 angles, and rounded in front, the curve being less at the margin of the median line of 

 the anterior interradia than quite in front. There is a slight depression where the 

 petals spring from the test. 



The petals are widely open, slightly swollen, have broad interporiferous areas ; 

 and the zone of pores, broad in the third quarter of the length, attenuates towards the 

 open extremity. 



The anterior odd ambulacrum is the longest, and is long and ovate ; it is not 

 closed ; and the zone of the right side is slightly shorter than the other. The antero- 

 lateral ambulacra are the shortest and narrowest; the terminal pairs of pores of the 

 posterior zone tend to flare backwards. 



The postero-lateral ambulacra are of the breadth of the odd one, and are slightly 

 shorter. The ornamentation of crowded small tubercles is carried over the costse in a 

 single row. The actinal ornamentation is larger than the abactinal. The periproct is 

 close to the posterior edge, and the peristome is in a slight depression of the flat test. 



Length 55 millim., breadth 50 millim., height 10 millim. ; length of odd petal 

 15 millim., of antero-lateral 11 millim., of postero-lateral 14 millim.; breadth of 

 odd and postero-lateral petals 9*5 millim., and of the antero-lateral 8'5 millim. 



Locality. Kachh. Three or four miles N.N.E. of Piptir, from a bed higher than 

 those with Nummulites. Survey-number C 039 A.

2. Clypeastek Carteri, Duncan & 8laden. Plate XII, Fig. 12. 



The test is depressed, faintly rounded posteriorly, straight at the sides, rounded in 

 front, and slightly curved at the margin of the anterior interradia. The length is 

 greater than the breadth, and the breadth is very equal between the lateral ambulacra ; 

 the shape is that of a pentagon with the angles truncated and more or less rounded. 

 The margin is slightly tumid, and the rosette is slightly elevated. The petals are 

 slightly swollen and are widely open ; they are broad and have large poriferous zones. 

 The odd and the postero-lateral petals are nearly of the same length and are longer than 

 the antero-lateral. The postero-lateral petals are the broadest, and the odd one is the 

 narrowest, the antero-lateral being a little broader than it. The poriferous zone of the 

 odd ambulacrum is as broad as the interporiferous area, and that of the lateral petals is 

 nearly as broad. The postero-lateral interporiferous area is broader than the others. 



The ornamentation is small, but is less on the ambulacra, and a row of granules 

 extends along the costte. 



Length 63 millim., breadth 54 millim. ; breadth of posterior ambulacra 12 millim. ; 

 length of odd ambulacrum 15 millim.
