An exhibiting to the Geological Society some interesting fossil shells^ col- 

 lected in Cutch by Capt. Smee^ of the Bombay army, I have to make my ac- 

 knowledgements to Mr. James de Carle Sowerby for his assistance in deter- 

 mining the various specimens. The locality from which they were obtained 

 is in the province of Choorwaugur, between the 23rd and 24th parallels of 

 north latitude, and the 70th and 71st degrees of east longitude. On the east 

 and north it is bounded by the celebrated Runn, a tract of low lands, one 

 part of which is periodically overflowed, another is salt marsh, and a third 

 sandy desert; and, extending from the mouths of the Indus to the head of the 

 Gulf of Cutch, it gives the country an insular character. 



I shall confine the notice to a few short remarks on the specimens. 



Of Ammonites there are several species, and one of them bears so close a 

 resemblance to A. Harvei/ii of the oolitic series of England, that Mr. Sowerby 

 cannot satisfy himself that there is any difference (see fig. 1, wood-cut, 

 p. 719). The new species are figured in Plate LXI. The whole of the 

 specimens were obtained from the red rock in the neighbourhood of Shah- 

 poor and Kuntkote. 



Trigonia. Imbedded in the mouth of A?nmomtes Harveyii (woodcut, fig. J, 

 p. 719), is apparently a young specimen of Trigonia costata, a shell cha- 

 racteristic of the oolitic rocks of Englandf. Another species which Mr. 



* This paper was read previously to that by Capt. Grant on Cutch, printed iu the second part 

 of the volume, and the delay in its publication has been owing to various causes which it is unne- 

 cessary to state. 



f A full-grown shell of this species is given in PI. XXI. fig. 16, of the illustrations to Capt. 

 Grant's Memoir.
