" A Description of the Skull and Skeleton of a peculiarly modified 

 Eupicaprine Antelope, Myotragus lalearictis (Bate)." By Dr. C. W. 

 Andrews, E.E,.S. 



Myotragus halearicus (Bate) is a peculiarly modified rupicaprine 

 antelope, remains of which were discovered by Miss D. M. A. Bate in 

 cavern deposits in Majorca and Minorca (see ante, pp. 337-45). 



The dentition is very remarkable. Instead of having three incisors 

 and a canine on each side of the mandibular symphysis as is usual in 

 the Bovidse, the canines and the two outer pairs of incisors are 

 wanting, while the median incisors are enormously enlarged rodent- 

 like teeth, growing from persistent pulps. The premolars are reduced 

 in number and the molars have very high crowns. 



The feet are remarkable for the shortness and stoutness of the 

 metacarpals and metatarsals, which are quite similar to those of the 

 Takin (Budorcas). The animal seems to have been adapted for 

 climbing on steep crags and cliffs, and probably lived on very hard 

 vegetation. A full account of the osteology and dentition is given in 

 the paper.

The following communication was read : — 



"The Ballachulish Fold near the Head of Loch Creran (Argyll- 

 shire)." By Edward Battersby Bailey, B.A., F.G.S. 



The district of Lower Glen Creran has recently been much more 

 carefully examined than heretofore. The course of the Ballachulish 

 Fold had already been determined with approximate accuracy. The 

 purpose of the present paper is to draw attention to two phenomena 

 strikingly illustrated by the local evidence : — 



(1) The complexity of the slides affecting the Ballachulish Core, 

 and the correlated (quite exceptional) occurrence of more groups 

 towards the close of the fold, south-east of the River Creran, than 

 towards the gape, north-west of the same. 



(2) The intense secondary refolding of the Ballachulish Fold, and 

 the resultant sinuous outcrop of the Ballachulish Core. 



Dr. Douglas Mawson gave an account of the geology and giaciation 

 of the Antarctic regions, as observed in his recent expedition, and 

 exhibited a series of magnificent lantern-slides, many of which 

 reproduced the natural colouring by direct photography. A 

 unanimous vote of thanks, proposed by the President and seconded 

 by Dr. J. J". H. Teall, was tendered to Dr. Mawson, by whom it was 

 briefly acknowledged.
