Boulenger, in his account of the Venezuelan Phyllobates trinitatis, believed that the larvae attached themselves to back of the parent with the object of being transported from one pool to another. Brauer shows, however, that in Arthroleptis the attached condition is not a temporary one, but that a large part of the development takes place in the back of the male. Fishes of Ecuador. -In the Bolletino of the museum at Turin Dr. E. A. Boulenger has a valuable paper on the fishes of Ecuador,

... ted by Dr. Enrico Festa. Forty-three species are described, many of them new. Among the latter are two marine catfishes, Arius (Ja'chysurus) feske and 4. (Galeic/t/zys) labiatus. No. 388.] REVIEWS OF RECENT LITERATURE. 345 distinct family of Lamnoid sharks from Japan under the name of MitIsukuri-ina ;-uslonli. The genus is apparently unique among living forms, its nearest living relative being the genus Odontaspis of Agassiz, a group which contains few recent sharks, but which is rich in fossil forms. American Gordiacea. -Dr. T. H. Montgomery concludes his second paper on Gordiacea of certain American collections (Proic. Cad. A4ced. Sci., Ser. 3, Zoo.l., Vol. I, No. 9) with a synoptical key for determining the species of Gordiacea of the North American continent north of Mexico. Development of the Eel. -An excellent summary of our knowledge regarding the development of the eel is given by Dr. A. Kbnig in Ai~t/ie~ii. d. Sect. of Nzt-ak. des Oesterrieic . 7 u-ristesi Ccub, X, Nos. 8 and 9. BOTANY. A New School Botany. -The modern reaction against the oldfashioned way of making elementary botanical instruction consist chiefly in " analyzing " flowers is well exemplified in the present text-book.' WVith the recommendation that " analysis " be postponed, "even though the pupil may pursue it independently at a later time," the author introduces the student at once to a physiological and microscopical study of the protoplasm and vegetative organs of a few Algal, Fungal, Bryophytic, Pteridophytic, and Spermatophytic types. These same types, together with others, are then studied in the second part as regards their morphology, reproductive processes, and life history. This part ends with a cursory view of some of the more important families of flowering plants. A final part devoted to ecology calls attention to a few examples of interesting adaptations of various organs to the work of nutrition, protection, pollination, dissemination, and germination, and directs the student to profitable lines of study in geographical distribution with special reference to plant formations. In an appendix suggestions are given for the collection and preservation of material, note taking, etc. The illustrations are mostly good, some being of unusual excellence.
