Dr. R. HORST. 



I. On the supposed synonymy of Bufo cruentatus and 

 Bufo horhonicus. 



Being occupied with an examination of the frogs from 

 the Malayan Archipelago in our Collections , the type-spe- 

 cimens of Bufo cruentatus (Schleg.) Tschudi and Hylaplesia 

 boiéonica Kuhl & v. Hass. came under my hand , and I was 

 not a little surprised to see that the later authors believe 

 those two species to be identical. 



Our specimens of B. cruentatus quite agree with the des- 

 cription given by Dumeril and Bibron , but those of B. 

 horhonicus (Peters has first pointed out that Hylaplesia is a 

 true Bufonid) differ by so striking characters , that this species 

 is recognised at first sight and the confusion of both spe- 

 cies must certainly be imputed to the incomplete descrip- 

 tion of Boie and to the rarity of the specimens. However 

 it is very strange that Peters, who first pointed out some 

 differences between B. cruentatus and B. horhonicus (Monatsb. 

 Berlin. Acad. 1863, p. 81), afterwards declared that they 

 must be taken for the same (loc. cit. 1867, p. 34).
