AMPHIBIA EROM THE CONGO WITH DES- 



CRIPTION OF A NEW SPECIES. 



L. SCHILT HUIS, 



Conservatrix to the Museum of Zoology of the University, Utrecht. 



Ainong the numerous animals , wbich have been presented in 

 the course of the years 1886 — '88 to the Zoological Museum of 

 the University of Utrecht by Mr. A. Greshoff of Boma. (Congo, 

 W. Africa) , and which were all collected in that locality , there 

 are seven species of Amphibia, two of thein being new to science. 



One is a Rana spec, but the only example received is too 

 young to be of any value as a type for a new species. The other 

 is a Hylambates, to which I propose to confer the name of the 

 kind donor, by whose zealous endeavours so many valuable ad- 

 ditions have been made to the Utrecht University Collections. 

 The list of the Amphibia is the following : 



Rana sp. n. young. 



Rappia marmorata Rapp., two specimens , one of them = Rappia 

 (ELyperolius) parellela , Günth. 



Rappia pusill-a? Cope. , two specimens. As they are females, 

 the characteristic vocal vesicle , which Prof. Cope mentions , is 

 absent (Proc. Acad. Philad. 1862 p. 343). They agree with R, pusilla 

 Gope by their coloration , by the presence of a faint brown line
