E. Lydelcker — ShvaUk Antelopes. 169 



If we compare small things with great, a parallel may be drawn 

 between the section of metamorphosed Cambrian rocks at Forlorn 

 Point, CO. Wexford, and the section at the Eapids out of the Lake of 

 the Wood, one being a pocket edition of the other. In the Forlorn 

 Point section going southward, we first meet schists, then a hard 

 boundary, then gneiss, and the latter after a time graduates by alter- 

 nations into schists. In the Canadian section going northward, first 

 you meet schists, then a hard boundary, south of which is gneiss ; and 

 the latter still further north having in it alternations or subordinate 

 beds of schists : while there is also a bay that seemed to have been 

 denuded into softer strata than the gneiss ; of this, however, I could 

 not satisfy myself, as the nature of the country and time did not 

 permit. 



I am aware that Sterry Hunt and others have suggested that these 

 older rocks accumulated under circumstances quite different to those 

 of the accumulation of the younger rocks ; they in a great measure 

 being more chemical than sedimentary accumulations. Such a sup- 

 position, however, now that I have been able to study the Canadian 

 rocks, appears to me unnecessary, as these supposed chemical accu- 

 mulations have their characters in common with rocks of the old 

 country, — rocks whose characters can be proved by ocular demonstra- 

 tion to be due, not to chemical accumulations, but to metamorphic 

 action, — that took place long subsequent to their original deposition. 



Some of the suggestions that I have put forward in this paper may 

 possibly have already been ventilated by American geologists. If 

 this should happen to be the case, I beg leave to assure the originator 

 of the suggestion that his claim has been ignored not purposely, but 

 on account of my being unacquainted with the paper in which it was 

 put forward. 



V. — A Eevision of the Antelopes of the Siwaliks. 

 By R. Lydekkek, B.A., F.G.S., etc. 



A FEW years ago I described^ some remains of Antelopes from 

 the Pliocene Siwaliks of India, when I employed the generic 

 term Antilope in the wide sense in which it was used by the older 

 zoologists and paleeontologists. At a later date" I was enabled to 

 refer two of the species thus designated to two of the genera of 

 Antelopes as at present classed; and at the same time mentioned 

 some other forms. A recent examination of all the remains of this 

 group from the same deposits contained in the British Museum has 

 enabled me to make a more exact determination in the case of 

 another of the species mentioned in my first notice, and also to 

 indicate the existence of other forms closely allied to existing 

 African Antelopes. These new forms I hope to have an oppor- 

 tunity of describing on a future occasion, and, therefore, now con- 

 tent myself with merely giving a list of the species which I can 

 at present recognize. The ill-defined character of some of the
