Vol. XV, pp. 15-17 February 18, 1902 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON/^ A NEW OPISTHOGLYPH SNAKE FROM FORMOSA. BY LEONHARD STEJNEGER. During a recent visit to the Naturhistorisclie Museum in Ham-burg, the authorities kindly allowed me to examine and de-scribe two specimens of an apparently new opisthoglyph snake collected by Dr. Warburg in Formosa. I am greatly indebted to Dr. Krsepelin, the Director, and to Dr. Pfeffer, the Curator, for permission to make the notes upon which the following description is based, as well as to Dr. Steinhaus, the assistant at the Museum, for kindly helping me in various ways. The snake in question belongs to the genus characterized by Boulenger (Cat. Snakes Brit. Mus. Ill, p. 59, 1896,) under the name of Dipsadmnorphus (Fitzinger, 1845). This name is clearly antedated by Fitzinger's Boiga of 1826. The latter is a composite genus it is true, and Boulenger there-fore quotes it in the synonymy of DipsadoniorphMS as ' ^ Boiga, part., Fitzing.", but on page 31 (Neue Classif. Rept.) Fitzinger expressly states that the genus Boiga is based upon "Merrem's Coluber irregularis.''^ This species, therefore, is the type of Boiga, a name which cannot be ignored simply because its own author dropped it lY years, after on account of its barbaric origin.
