60 THE TEKTIAEY FOSSIL ECHINOIDEA 



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

 those with Nummulites, Survey-number C 039 (a).

 Fig. 12. The test, from above : natural size. 

 This species, closely allied to the last, has broader and coarser poriferous zones 

 and a larger ornamentation.

The test is depressed, rather tumid at the margin, slightly hollowed out actinally, 

 and very shghtly elevated at the rosette. The lecgth is greater than the breadth, 

 and the greatest breadth of the irregular pentagon is on a line with the antero-lateral 

 ambulacra. The margins are slightly reenteringly curved on the anterior interradia, 

 and the front and hinder angles are bluntly rounded. 



The petals are very long, rather narrow, decidedly tumid, not very broad, and are 

 widely open distally. The poriferous zones are rather straight, and the interporiferous 

 areas, tumid and narrow, are not more than double the width of the poriferous zones. 

 The odd ambulacrum is the. longest, and its right poriferous zone is shorter than its 

 fellow; its breadth is the same as that of the others : the openness of the distal end 

 is remarkable. The antero-lateral ambulacra, next in length, are widely open, and the 

 posterior poriferous zone turns back at the end. The posterior ambulacra are the 

 shortest, and their breadth is the same as the others. The ornamentation is distinct, 

 small, and is closer within the ambulacra ; a line of tubercles is on the very low costse. 



Length 70 millim., breadth 61 millim. ; length of odd petal 25 millim., of antero- 

 lateral 22 millim., and of posterior 20 millim. ; the breadth of the petals is 10 millim. 



Locality. Kachh. Upper part of Nummulitic group, with Orbitoides. Falora 

 river, near B^bua Hill. Survey-number C 166 f.

A portion of a test, which has weathered out of a mass of Nummulitic limestone, 

 shows much of the anterior part above the apical system, the anterior and antero- 

 lateral ambulacra, and part of the posterior ambulacra. The interporiferous areas of 

 the antero-lateral and postero-lateral ambulacra are tumid and raised above the level
