224 THE FOSSIL ECHINOIDEA 



Indian forms; and although we hesitate from drawing definite comparisons with 

 western species, we venture to believe that when more perfect specimens are studied, 

 and such comparisons are possible, S. simulans will prove to be readily distinguishable. 



Dimensions. Length of the test 40*5 millim., breadth 37 millim., height about 

 24"5 millim. 



Locality. In the Khirthar series of strata : Baili, west of Tong. Survey-number

3. ScHizASTBR Baluchistanensis, d'ArcMac & Haime. 



We refer to this species a single small test of Schizaster, the preservation of which 

 is, however, so bad as to be quite unfitted for illustration, and the determination is 

 based entirely upon its general form and character. As the species occurs in other 

 strata, and has been noticed by us in the description of the Fossil Echinoidea of Kachh 

 and Kattywar, further remarks are here unnecessary. 



The Khirthar example is of small size, its length being about 28 millim. 



Locality/. In the Khirthar series of strata : Pujana lak (pass), east side of Hothian 

 Hill. Survey-number ^. 



4. ScHizASTEE (I), sp. Plate XXXVI, Figs. 20 & 21. 



There is a single badly preserved test in the collection which is unquestionably 

 distinct from any of the other Indian Echini, but the condition of the fossil is such 

 that any useful description is impossible, and we are in great doubt even as to its 

 generic position. The form has been placed provisionally as a Schizaster mainly on 

 account of the shortness of the posterior pair of petals and the apparent trend of the 

 anterior pair. There appear also to be indications suggestive of the former presence 

 of a fasciole passing below the periproct, -but this statement is purely conjectural. As 

 no useful remarks are possible on such an unintelligible fossil, it is obviously necessary 

 to await the receipt of more perfect specimens before any specific diagnosis can be 

 given ; meanwhile the figures of the fossil in question contained in Plate XXXVI. will 

 serve for the identification of the form. 



Dimensions. Length of the test 50 millim., breadth 45 millim., height 32-5 millim. 



Locality. In the Khirthar series of strata : About seven miles north-east of Bula 

 Khan's Thana. Survey-number ^.
