at the extremity of the delta. At SO yards from the shore, he 

 found 14 fathoms of water; at 60 yards, 23 fathoms, and at 120 

 yards no bottom at a depth of 32 fathoms. 



A communication by Colonel Sykes was then read, entitled, " A 

 Notice respecting some Fossils collected in Cutch by Captain Smee, 

 of the Bombay Army." 



The district from which the specimens were procured is situated 

 between the 23rd and 24th parallels of N. lat. and 70th and 71st 

 degrees of E. long., and is bounded on the E. and S. by the Run. 

 The fossils consist of four species of Ammonites, one of Trigonia, 

 two of Astarte, one of Corbula, one of Grypheea, and a coral 

 having a nummulitic form. One of the Ammonites has a general 

 resemblance to A. Wallichi, and another agrees in some respects 

 with J. NepauUensis, both of which occur in the fossils procured in 

 the Himalaya I'ange ; one specimen of the Gryphsea is stated to 

 resemble closely the Gryphsea of the Oxford clay of England ; and 

 the coral belongs to the genus which occurs in the Kressenberg iron 

 ore. Specimens of silicified wood, lignite and alabaster from Cutch 

 were also exhibited, and of durable oolite from near Poorbunda, on 

 the W, coast of the periinsula of Goojrat ; and it is stated that the 

 same rock is found abundantly at Raujcote in the centre of the 

 peninsula. In conclusion. Colonel Sykes observes, that if English 

 analogies may be taken for a guide, the district from which the 

 above fossils were obtained would seem to be composed of second- 

 ary rocks, as Ammonites, Trigonia, and Gr5'phgea have not been 

 found in England higher than the upper chalk. 



A paper was afterwards read " On the Gravel and Alluvial De- 

 posits of those Parts of the Counties of Hereford, Salop, and 

 Worcester which consist of Old Red Sandstone ; with an Account 

 of the Puffstone, or Travertin of Spouthouse, and of the South- 

 stone Roch near Tenbury," by Roderick Impey Murchison, Esq., 

 V.P.G.S. 



The district of which the transported materials are described 

 is bounded on the west by the transition rocks, extending from the 

 environs of Ludlow to the S.W. of Kington, and on the E. by the 

 Abberley Hills, thus including a large portion of the trough of old 

 red sandstone. It is shown that all the detritus within these limits 

 has been derived from the adjacent rocks. In the neighbourhood 

 of Kington bowlders of the contiguous ti-ap rocks are found upon 

 the talus of the Ludlow rocks, extending to the edge of the old 

 red sandstone, and in the plain W. of Ludlow the surface of the 

 old red is frequently covered with coarse gravel, in which are 

 numerous fragments of the trap rocks of the W. of Shropshire. In 

 general, however, the gravel is chiefly made up of the debris of trans- 

 ition rocks, the coarser varieties being found only near the boun- 

 dary of those formations. Detailed sections are given in the neigh- 

 bourhood of Ledbury; and the valley of the Teeme is particularly 

 described to prove that, on receding from the transition chains, 

 the gravel becomes more finely comminuted, and exhibits near 

 Tenbury the characters of lacustrine or fluviatile sediments, the
