86 DE. J. W. EVANS ON THE [Feb. 1 894, 



The last-named gentleman has kindly perused this paper, and I 

 have had the benefit of his observations upon it : they have especial 

 value on account of his extensive acquaintance with the geology of 

 other parts of Brazil. I am indebted to Mr. A. M. Davies, F.G.S., 

 for invaluable assistance in seeing this paper tbrough the press, 

 and to Mr. W. Ilupert Jones for careful revision of the references 

 throughout, a task which I was unable to undertake myself, on 

 account of my being now resident in India. 



The map which accompanies the present paper (PI. VIII.) shows 

 the routes taken both by Castelnau and by myself, and also the geolo- 

 gical structure of the country, so far as I have been able to ascertain 

 it. I have inserted a few details on the authority of Castelnau, but 

 it is not easy to gather the exact nature of the rocks from his 

 descriptions.
