Auk Clipperton Island lies in latitude Io0 I7r north and I090 I31 west, anG about 6oo miles distant from the mainland, the nearest point of which is the west coast of Mexico, near Acapulco. It is littie more than a coral reef, practically without vegetation, and its land fauna consists of a few species of sea birds, which resort to it in immense numbers for a breeding station, a single species of lizard, a dragonfly, a beetle, and a few diptera. Cocos Island, situated about five degrees further south and some twentytwo degrees further east, off the west coast of Costa Rica, and about 250 miles from the mainland, is mountainous and covered with trees and a dense undergrowth. The plant species are few, however, and the land fauna consists of a fewv indigenous birds, a lizard, and a few species of insects. Though visited by several kinds of water birds, it is not, like Clipperton Island, a great breeding resort for sea fowl. Both islands are described in much detail, and most of the birds obtained at each are described at length. The birds recorded from both islands number only 15 species, of which only five -all boobies and terns-are recorded from Clipperton Island and io from Cocos Island, while two are common to both localities. Two of the species, a tern and a booby, were first described by the authors of the present paper from specimens taken by them at these islands. Of the four indigenous land birds found at Cocos, three are peculiar to the island, -two of them having been first made known by Mr. A. W. Anthony in I895. -J. A. A. Knight's 'The Birds of Wyoming."-This is a fully annotated and well illustrated list, based in part on "published reports pertaining to the birds of the State," partly on unpublished observations of ornithologists or collectors of Wyoming birds, and partly on collections made especially for the museum of the University of Wyoming by Mr. Chas. W. Gillmore, now of the Carnegie Museum. Mr. Knight, being a geologist, makes no claim to being an ornithologist, and appears to have prepared the work in response to constant inquiries "for some literature on the birds of the State," which, as curator of the museum, he felt called upon to furnish. He is entitled to congratulations on having prepared what seems to be an excellent list of the birds of Wyoming, which, with the other pertinent matter included, forms a ' Bulletin' that must be of great assistance to students of Wyoming birds. The introductory matter includes a resum6 of the literature pertaining to the subject, ' A Note on Studying Birds,' and a reprint of Prof. Laurence Bruner's ' Birds in their Relation to Agriculture,' this preliminarv matter occupying pp. 1-23, while a supple-'The Birds of Wyoming.
