A considerable number of examples belonging to this species are in the collection, 

 but all are unfortunately more or less broken, crushed, or badly preserved. As the 

 form was described in detail in the fasciculus on the Tertiary Echinoidea of Kachh and 

 Kattywar it is unnecessary to repeat the description there given. The species is also 

 found in the Nari strata of Sind. 



Localities. In the Gaj series of strata: — 



i. Scarp at Kupo-jo-lak, or pass on the M61 range, west of Shah-beg (same locality 

 as G -4-2°). Survey-number G ^°l-. Some specimens also bear the Survey-number G ^pf-. 



ii. About three miles south-east of Tong. Survey number G -3%-. 



iii. Naig-Nai valley, twelve miles south of Shah Ehiii. Survey-number G -^4^0^. 



iv. Gaj river, Khirthar range. Survey-number G ^-|-^. 



V. Near the top of the pass, on the Mol range, west of Thana Shah-beg. Survey- 

 number G ^li- f.

2. ScHiZASTEE SUFFLATUS, Duncan & Sladen. Plate XLIX, Figs. 7-9. 



Test of medium size, nearly as broad as long, with the greatest breadth situated a 

 little behind the centre. Marginal contour suboval, more contracted in front than 

 behind, and deeply notched by the anteal sulcus. Apical disk slightly excentric 

 posteriorly. Seen in longitudinal profile, the greatest height is situated considerably 

 behind the apical disk, the abactinal surface sloping continuously from this point to 

 the anterior margin, which is tolerably thick and tumid ; whilst the region of greatest 

 height is the summit of a convexity, which passes with a rather rapid curve to the 

 posterior extremity. The periproct appears to have been rather higher in position 



t The number " 42 " i§ indistinct.
