Genus MEGALIXALUS Giinther 



MEGALIXALUS FORNASINII (Bianconi) 



Euchnemis fornasinii Bianconi, 1850, Spec. Zool. Mosamb., Rept., pi. 5, fig 1. 



(Mozambique.) 

 Megalixalns fornasinii Boulengeu, 1882, Cat. Batr. Sal. Brit. Mus., p. 130. 



1 (U.S.N.M. 12765) Southeast Africa. (Exchange British Museum.) 



This frog, discolored, rubbed, and generally in a poor state of 

 preservation, bears a very old parchment label '' Eucnemis modesta 

 sp. n." Giinther, ^^ under the name of Hyperolius modestus, gives us 

 the following information but no description: ^' Eucnemis modestus 

 (Schleg.), Nomenclat. Rept. Mus. Berol. 1856, p. 36 (without descrip- 

 tion), a Adult; bad state. Gold Coast. From Mr. Parrey's collec- 

 tion as Eucnemis modestus." I have also verified that the citation from 

 Schlegel is without description. The Gold Coast frog was subse- 

 quently referred by Boulenger to Rappia concolor (Hallowell) and was 

 probably not conspecific with the Southeast African frog before me. 



My reference of it to the genus Megalixalus is necessarily somewhat 

 arbitrary, for it is impossible to ascertain the condition of the pupil. 

 On placing it side by side with undoubted examples of M. fornasinii,. 

 however, it apparently agrees with it in every detail. Its large 

 size — 36 mm. — rules out the possibility of its being concolor and also- 

 the majority of East African species of Hyperolius. 



MEGALIXALUS LOVERmGII Procter 



Megalixalus loveridgii Procter, 1920, Proc. Zool. Soc. London, p. 418. (Moro- 

 goro, Tanganyika Territory). — Barbour and Loveridge, 1928, Mem.. 

 Mus. Comp. Zool., vol. 50, p. 227. (Dar es Salaam and locahties in Uluguru 

 and Usambara Mountains.) 



1 (U.S.N.M. 57803) Ukami, Tanganyika Territory. (Hurter) 1899. 



A 32-mm. example, practicallj'^ topotypic of the species, for Moro- 

 goro is in the Ukami country. It bears a label M. fornasinii, a 

 species with which M. loveridgii was long confused until separated by 

 Miss Procter. The minute black spines which cover the upper- 

 surface of loveridgii immediately distinguish it from the older species.

 described on the basis of a single female from Duque de Bragan^e, Angola
