Bufo biporcatus Tschudi. 



Plate 0, fig. 21, and Plate 8, fig. 35. 



Tschudi, Class. Batr., 1838, p. 51 (not p. 88). Boulenger, Cat. Batr. Sal. Brit, mus., 1882, p. 311. 

 (ref. to Tschudi, p. 88, nomen nudum). 



Type locality: — Java, collection of Kuhl. 



Curiously enough we did not once meet with this species in Java, but Bryant 

 got one at Buitenzorg (fig. 35). There is a single young example (fig. 21), 

 from Makassar, Celebes (Barbour coll.). 



Van Kampen in his table of distribution of East Indian Amphibia (Zool. 

 ergeb. Max Weber's Reise, 1907, 4, 2,) records this species from the mainland of 

 Asia (c/. also Boulenger, Fauna Brit. India. Rept. Batr., 1890, p. 507). Among 

 the islands it occurs on Sumatra, Borneo, Java, Madura, Lombok, and Celebes. 

 Bleeker has reported it from Bali, and this is probably correct. 



Bufo cavator Barbouh. 

 Plate (), fig. 22. 

 Barbour, Proc. Biol. soc. Wash., 1911, 24, p. 21. 

 Type locality: — Ampenan, Lombok. 

 This species is known from the type alone, from which the figure was drawn. 



Bufo asper Gravenhorst. 



Gravenhorst, Delic. Mus. zool. Vratislav., 1829, p. 58. Boulenger, Cat. Batr. Sal. Brit, mus., 1882, 

 p. 313. 



Type locality: — Java. 



This large toad does not seem to be common anywhere. It is very rare 



in Batavia, and constant search, the offering of special inducements to the 



natives, etc., brought in only three adults at Buitenzorg. Here also Bryant 



got the same number as well as an additional one at Gunung Bunder, Mt. Salak. 



It occurs on Sumatra, Borneo, and Java, as well as on the mainland up to 



Tenasserim. 



Bufo borbonicus (Boie). 



Plate 8, fig. 33.

Type locality: — Java. 



Boulenger, in his synonymy of this species, mixed two very widely different 

 species, this one and Bufo cruentatus Tschudi. Both of these were recognized 

 by Tschudi as being wholly unlike. Van Kampen (Zool. ergeb. Max Weber's 

 Reise, 1907, 4, 2, p. 416) says in a note "Bufo cruentatus: auch diese Art gibt
