Abstract
THE February number ofthe American Naturalist (Vol. iii. No. 12) contains only three original articles, and of these the first and most important is really,a reprint of Professor Wyman's observations on the development of the thornback, with a few introductory remarks on the natural history of the skates, by Mr. F. W. Putnam. The other two are the continuation of Mr. J. A. Allen's notes on the rarer birds of Massachusetts, and a paper on common fresh-water shells, by Mr. E. S. Morse. Professor Williamson's article on Bathybius is reprinted from the Popular Science Review.
