OF KACHH AND KATTYWAR. 73 



The genus is not found in the Eanikot series of Sind, but in the higher and main 

 Nummulitic limestone of the Khirthars. 



Several species and a variety of the genus Echinolampas are described from the 

 Nummulitic series of Kachh. The commonest are high, long Conoclypoid-looking 

 forms, eminently suggestive of Egyptian affinities. The beautiful forms described 

 by de Loriol from the Nummulitic of Egypt and Lybia, and named by him JEchino- 

 lampas Fraasi and Osiris, are closely allied to the Kachh species, which, however, do 

 not appear to have any great affinities with the Echinolampads from Sind. Amongst the 

 more depressed forms from Kachh one resembles Uchinolmnpas discoideus, d'Archiac, 

 but it is nevertheless distinct. 



Amongst the flat and oval species is Hchinolampas Vicaryi, d'Archiac ; and probably 

 it was from Kachh that the typical specimen came. 



Cotteau's genus Peripneustes is represented in the Nummulitic of Kachh; 

 and we have noticed the affinities of the genus to Euspatangus and Macropneustes 

 in the description of the species, which stands rather alone. It gives a Nummulitic 

 facies to the collection, which is intensified by the presence of two large depressed 

 Hemiasters, Linthia-like in shape ; they have peripetalous fascicles only. 



Another Hemiaster, H. carinatus, nobis, is mimetic of the shape of Schizaster 

 Baluchistanensis, d'Archiac, but has two generative pores, a peripetalous fascicle only, 

 and great keels on the anterior and posterior interradia. It is a very marked form. 



The Schizaster which has given much trouble to some students of the European 

 Nummulitic, and which has the not very euphonious name BeloutcMstanensis, d'Archiac 

 (and which may be spelt Baluchistanensis), is one of the types described by d'Archiac 

 and Haime from the Hala range — a geographical fallacy, but meaning the hill-country 

 of Western Sind. The typical specimens were so rolled that no ornamentation could 

 be seen, and the position of the fascicles is open to doubt. The shape, however, is 

 peculiar. The great height of the posterior keel adds to the general height of the 

 hinder part of the test, the ambulacra are very different in size, and there are four 

 generative pores, the two anterior being on a line with the anterior and antero-lateral 

 ocular pores. The actinal plastron is rather convex. 



A variety is found in Kachh, in the Nummulitic series, but it is not a common 

 form. 



The JEuspatangi of the Nummulitic deposits of Kachh have given much trouble, on 

 account of their resemblance to Mareti(e. Indeed it appears that the genus which was 

 the last defined must be absorbed by that which first attracted the notice of Agassiz. 

 There is no generic distinction between Euspatangus, Agass., and Maretia, Gray, 

 except in the existence of a peripetalous fascicle in the first named. In some 

 Euspatangi the fascicle is well developed, in others it is seen with difficulty, and in the 

 form Euspatangus affinis, Duncan and Sladen, from Kachh, only a vestige exists, about 

 3 millim. in length. On the ether hand, Maretia planulata has occasionally a partial 

 fascicle, and a fossil form from Australia has it distinctly. It* is in cur opinion im- 

 possible to form an intermediate subgenus, and unreasonable to separate forms generically
