1906.] OF THE GENUS jSTEOTOPHRYNE. 59 



somewhat the descriptions of the authors. I was able to identify 

 as one species two that had previously been considered different. 



I add to these observations the description of a new species 

 from German East Africa, the type of which is preserved in the 

 Basle Museum, and conclude this paper with a key for the deter- 

 mination of all the known species of the genus. 



I am happy on this occasion to express my best thanks to 

 Dr. Mocquard, of Paris, who was so kind as to allow me to 

 examine the types of the species described by him. I am also 

 much obliged to Prof. Boettger, of Frankfort a/M., and to Prof. 

 Tornier, of Berlin. The former has been kind enough to send 

 to me the type of his N. exigua which is presei^ved in the 

 Senckenberg Museum ; to the latter I am indebted for the 

 loan of the types of two species in the Berlin Museum. I am 

 particularly indebted to Mr. G. A. Boulenger, who has obligingly 

 placed at my disposal the valuable collection in the British 

 Museum (Natural History), and has been so kind as to verify the 

 work done in his laboratory. 



1. ISTectophryne afra B. & P. 



Buchh. k Peters, Mon. Berl. Akad. 1875, p. 202, pi. ii. f. 5. 

 Boulenger, Cat. of Batrach. Sal. p. 279. 



Examined : The type specimen (Berlin Museum) : Cameroon. 

 6 specimens (Brit. Mus.) : Efulen, S. Cameroon, 

 and Bio Benito. 

 This species occupies quite a special place as regards its webbed 

 fingeis, the subarticular tubercles of which imitate small lamellee. 



2. ISFectophryne misera Mocq. 



Mocquard, Le JSTaturaliste, 1890, no. 82, p. 182; Nouv. Arch. 

 Museum Paris, ser. 3, torn. ii. p. 161, pi. xi. f. 7. 



Examined in Paris Museum : Type specimen, N. Borneo. 



In Brit. Mus. : 10 specimens from Paka-Paka, 10,000 feet, 

 Kina-Balu, N. Borneo. 



This species has also strongly webbed fingers, but no sub- 

 articular tubercles. Sometimes the tibio-tarsal articulation does 

 not quite reach the tympanum.
