The rich and very well preserved collection of batrachians 

 brought home m 1892 from Cameroon by Professor Y. Sjöstedt 

 and at present kept in the zoological museum of Gothenburg, 

 was placed at my disposal through the kindness of the late 

 director of this museum Dr. A. Stuxberg and my friend Mr. 

 J. Sjöstedt, to whom I want to express my great gratitude. 



The collection contains 203 specimens representing 24 

 species, three of which seem to me to be new. Preliminarily 

 I have described them in a paper : ' 'Neue Batrachier aus 

 Kamerun von den Herren Dr. Y. Sjöstedt und Dr. R. Jungner 

 gesammeW in Verhandl. d. k. -k. zool. bo tan. Gesellsch. in 

 Wien. 1903, p. 141, and now giving the figures I repeat the 

 descriptions as well, in order to have figures and descriptions 

 in the same place. 



Beside these three new species I have also established a 

 new form of the genus Arthroleptis, which, for the present, 

 I have placed as a variety of A. variabilis Matschie, though 

 perhaps it ought to be regarded as a distinct species. 



In the list of the 24,true species Hylamhates hrevirostris 

 Werner is not counted, represented in the collection by three
