IIATRACIIIAXS FROM WEST AFRICA 



From snout to vent 65 millim. 



A single female specimen from Musola, Fernando Po, oOO to 

 800 m. altitude. 



This species is allied to H. aubryi, but well distinguished by 

 the shorter hind limbs and the position of the vomerine teeth. 



47. Hylambates calcaratus, Blgr. 

 Cameroon: Buea, 800-1200 m. 



48. Hylambates rufus, Reichen. 

 Cameroon: Buea, 800-1200 m. 



Fernando Po: Punta Frailes, Basile, 400-600 m. 

 French Congo: Fernand-Vaz. 



Several specimens, belonging to three colour varieties: the 

 typical form described by Reichenow, the var. notata, Peters, 

 and the var. boulengeri, Wern., or combining characters of these 

 three forms. 



49. Hylambates palmatus, Peters. 

 Cameroon: Buea, 800-1200 m. 

 Fernando Po: Punta Frailes. 



50. Hylambates brevirostris, Werner. 



Fernando Po: Basile, 400-600 m. , Bahia de S. Carlos, 400 m. 



The specimens are uniform green above, and the skin of the 

 back is strongly granulate, almost as much as on the belly; these 

 granulations may extend over the tympanic area. 



Our knowledge of the species of this genus has been greatly 

 extended since the publication of the British Museum Catalogue 

 in 1882. I have made a careful revision of the specimens pre- 

 served in the Museum and compared them with the descriptions 

 of other authors. As stated above I cannot accept some of the 

 species recently described by Barboza du Bocage. The large ma- 

 terial collected in South Cameroon by Mr. G. L. Bates shows 

 Mocquard's Hylambates ocellatus to be only a colour variety 

 of H. aubryiy Peters's dorsalh is perhaps no Hylambates 

 at all, whilst Boettger's H. microtympanum has proved to be a 

 Rhacophorus. After these omissions we have still 22 species, 

 which are briefly defined in the following synopsis.
