 closely related to, those in the Midlands, The rarity of tourmaline 

 rocks in tliat region is the only difficulty in looking to it or its 

 vicinity for the main source of these pebbles. 



2. " Further Evidence of the Skeleton of Eurycarpus Owent.^' By 

 Professor H. G. Seeley, F.R.S., F.L.S., V.P.G.S. 



The original specimen from which this species was named was 

 obtained from the Sneewberg (South Africa) in 1876, and after 

 being doubtfully referred to Biciinodon was described and figured in 

 1889. It was presented to the British Museum by Mr. Thomas Bain 

 through Sir Henry Barkly. The skull was found with the complete 

 specimen, and a short memorandum of its characters, with a sketch 

 of the skeleton, including the skull, was made by Mr. T. Bain and 

 has been preserved in the Biitish IMiiseum. Half of the counterpart 

 of the slab was presented to the author by the Rev. C. Murray, and by 

 means of it complete casts of part of the skeleton have been obtained. 



From Mr. Bain's sketch the author is able to give some account 

 of the skull, including its dimensions. From the material mentioned 

 above, he gives new facts with regard to the vertebral column, the ribs, 

 the shoulder -girdle, the fore-limb, the hind -limb, and the armour, 

 which was present upon the limbs and the fore-part of the body. 



The locality from which the animal was obtained had already 

 yielded to Mr. A. G. Bain Lycosaurus pardialis, Tigrisiichus simus, 

 Cynosnchns suppostiis, Scalaposaurus constrictiis, and JDicynodon 

 leoniceps. It would therefore appear to be one of the chief 

 localities for the Lycosaurian types of Theriodontia and to be on 

 the horizon of the Dicynodon-heds. The recovery of the missing 

 half of the Murray slab, with the evidence of the skull and pelvis 

 which it would give, is to be desired in completion of our knowledge 

 of this fossil animal.

1. "Notes on the Geology of Gilgit." By Lieut.-Gen. C. A. 

 McMahon, F.R.S., F.G.S. 



This paper is based on observations in the field made by Capt. 

 A. H. McMahon, C.S.I., C.I.E., F.G.S., and Capt. J. R. Roberts, 

 I.M.S., and on the petrological examination of the specimens sent 

 home by them. It is divided into three parts. Part I refers to 

 the work of previous observers, and embodies a brief petrological 

 description of the lour granites and aplite intrusive in the sedimentary 

 rocks of Gilgit. Part II consists of a topographical account of the 

 Gilgit rocks from Askole and Nanga Parbat on the south to the 

 northern passes leading into the Russian Pamirs. Part III recites 

 the author's conclusions from the facts recorded in the paper. 

 Briefly stated, they are as follows : — 



That at one period in the elevation of the Hindu Kush the strata 

 were thrown into a series of folds and compressed into a series of 

 imiclinal beds with a vertical dip. 



That the direction of the main drainasce of the area was determined
