X. NOTES ON THE NEWLY DESCRIBED GENUS CACOPHRYNE DAVIS Recently Davis (1935) pointed out that the toad known in literature as Bufo borbonicus (Tschudi) or Nectophryne borbonica (Tschudi) does not belong to either of these genera, and that it even does not belong to the Bufonidae, for the species differs from the true toads (Bufonidae) in two important characteristics, as it lacks Bidder's organs and does not possess testes of an elongated shape. Moreover the pectoral girdle proved to be firmisternal instead of arciferal. A new genus, Cacophryne, in the family Atelopodidae, was erected for this species by Davis, and this author (1935, p. 90) mentions that possibly some other species at present included in the genus Bufo, i.e., Bufo penangensis (Stol.), Bufo cruentatus (Tschudi) and Bufo leptopus Gthr. might also belong to the genus Cacophryne. To ascertain whether this was really the case I examined some specimens of Bufo cruentatus (Tschudi) and two specimens of Bufo leptopus Gthr. Of Cacophryne borbonica (Tschudi) I examined some specimens for comparison. As I had but two specimens of Bufo leptopus Gthr. I only examined the pectoral girdle of one, and this proved to be decidedly arciferal as in the true Bufo's. Of Bufo cruentatus (Tschudi) and Cacophryne borbonica (Tschudi) I examined especially the osteological characters, and these led me to conclude that both species are congeneric, and that, therefore, cruentatus must also be referred to the genus Cacophryne Davis. The following notes may be given on the anatomy of Cacophryne borbonica and Cacophryne cruentata. The vertebral column consists of eight
