Hallo well, E. — "Notice of a Collection of Reptiles from the 

 Gaboon County, West Africa, recently presented to the 

 Academy of Natural Sciences of Philadelphia by Dr. Henry 

 A. Ford." Proc. Acad. Philad. 1857, pp. 48-72. 



Peters, W., and Buchholz, R. — " Zweite Mittheilung iiber die in 

 West Africa gesaminelten Amphibien." Mon. Berl. Ac. 1867,

 made by Miss M. H. Kingsley during her Travels on the 

 Ogowe River and in Old Calabar." Ann. & Mag. N. H. (6) 

 xvii. 1896, pp. 261-285.

Por the nomenclature and synonyms I must refer the reader to 

 the British Museum Catalogues. I have added references to 

 publications issued since the appearance of these general works. 



Mr. Bates's discoveries have enriched herpetology with 5 new 

 genera and 13 new species, some of which are of special mor- 

 phological interest. The discovery of HymenocMrus and Cardio- 

 c/lossa has extended our knowledge of geographical distribution 

 by adding African representatives to the families Pipida and 

 Dendrobatidce, the former having been based on the single South- 

 American genus Pipa, the latter being hitherto regarded as charac- 

 teristic of Tropical America and Madagascar. 



I wish to record my thanks to the Board of Curators of the 

 Philadelphia Academy of Natural Sciences for the loan of type 

 specimens described in 1857 by the late Dr. Hallowell.

One of the specimens collected by Mr. Bates on the Benito 

 River has been prepared as a skeleton. There are only seven 

 prsecaudal vertebrae, the first being formed by the fusion of two 

 (as is clearly proved by the large nerve-foramen in front of the 

 diapophysis).
