ence. “The alana of Anguilla, now embracing but 30 square 
miles could not readily have supported a fauna of which these 
uge Rodents formed a part.” “This, and other facts mentioned 
by Pomel, lend brobelsbey to the hypothesis of the latter author, 
that the subm ergence of the ranges connecting many of the 
islands of the ‘Antilles has taken place subsequent to Pliocene

well known dunyte of North Carolina, which occupies “ mainly a 
zone in the mountain plateau between the Blue Ridge and the 
Great Smoky Range 250 km. long and 15-30 km. wide” is dis-

“ Lenticular Hills. ote by gigs C. H. Hrrencoc.. 
(Letter to o J. D. Dana, dated Hanover, N. H., Nov. 27th.)—It is 
not common for me to find some of my views or descriptions 
ascribed to my father; but in your remarks about the “lenticular 
hills” (this Journal, TH, xXvi, p. 358), you speak of them as 
having been described by him. to glad to say that he would 
have invented a better as cg thiah “lenticular” hills, if he 
had described them. I suppose we may call them “drumlins,” 
as that term has been anid to them in Scotland.
