]44 BLANFORD : GEOLOGY OF WESTERN SLND. 



published in 1867. 1 The following are some of the forms collected? 

 besides those noticed above : Oslreajiemingi, Neriia schmideliana, Natica 

 longispira, N. decipiens, N. flemingi, Voluta teelaensis, Terebellum distortum,. 

 aud Rostellaria angistoma. 



West of Lainyan the rocks dip to the westward at low angles. A 

 fossil bed, apparently on the same horizon as the 

 lower of the two principal fossiliferous belts to 

 the eastward, abounds in Turritellce, the Rostellaria referred to B. 

 columbaria by D'Archiac and Haime, a Cassis, and a small muricoid 

 shell with elegant raised reticulated sculpture. The Rostellaria is a 

 characteristic species with a prominent tubercle at the upper (posterior) 

 termination of the lip, and the same form, as already mentioned, is 

 found in parts of the Laki range, and appears to be peculiar to this 

 horizon. 



In this direction, west of Lainyan, no Khirthar limestone is seen in 

 place, and the Manchhars appear to rest almost directly on the Ranikot 

 beds. But little rock, however, is seen, the plain of Manchhar beds 

 being much covered over by gravels and alluvial deposits. 



Section on road to A very good section of the upper Ranikot beds 



Kotr1, is also seen south-east of Lainyan on the road to 



Kotri via Bhada. 



At the top of the Ranikot beds the brown limestone passes up into a 



Ferruginous bed at yellowish-brown limestone with Ojjerculinee, and 

 base of Khirthar. ^ s a g a i n p asses i n t a dull whitish bed. Upon 



thjj latter there is found a highly ferruginous band, consisting in places 

 chiefly of brown haematite, and varying in thickness from 5 or 6 to 

 about 20 feet. It is usually more or less argillaceous, the upper part 



1 Mem. Geol. Surv., India, VI, p. 3. By mistake the footnote, containing the list of 

 these fossils, was printed on the wrong page, and it was made to appear that the species 

 enumerated were derived from a limestone, containing Foraminifera, which really belongs 

 to the Khirthar group, instead of from the " rubbly limestone of a yellow colour abounding 

 in fossils," and the other beds noticed on p. 4. The paper was printed during my absence • 

 from Calcutta, and I had no opportunity of seeing the proofs.
