all, and is either narrow and whitish, or broader and then pale brown. The lower 

 side is more or less speckled with brown. 



This species was originally established by BOULENGER 1895 on a small specimen 

 from Western Somali-land. Its known geographical distribution has thus been exten- 

 ded a great deal by this find at Kibonoto.

9 specimens from Kibonoto, Nov. 1905. 



I owe my best thanks to my friend D:r G. A. BOULENGER, who has kindly 

 determined this species and compared it with the type-specimen from Somali land.

specimens from Mombo, Usambara, June 1906. 



These specimens agree with PFEFFER'S description (1893) except that they 

 being well preserved, have no (through contraction in the spirit produced) dermal 

 folds. The black tympanic spot is as a rule extended over the eye to the snout. 

 The black round spots in the inguinal tract and at the shoulder are not constant 

 but only present in some specimens. The sternal tract is marmorated across with 

 blackish. There is no conical papilla on the tongue. By this characteristic it 

 is distinguished from Arthroleptis whytii BOULENGER 1897 * with which it agrees very 

 closely as well with regard to the description as to the figure.

18 specimens from Kibonoto. - 1 specimen found sitting on a rock on the 

 Massai steppe and agreeing in colour with the rock, Kibonoto 8 / 1905. --2 specimens 

 in a pond through which a rivulet with clear water ran, which emptied into the river 

 Sanya, the Kibonoto steppe "/ 1905. The frogs sat on the floating leaves of Nymphcea. 

 1 specimen Kibonoto Nov. 1905. 2 specimens from a rivulet, tributary to the 

 river Sanya 28 / 2 1906. 



It is extremely difficult to form any opinion as to which species some speci- 

 mens of Rappia belong. Characteristics derived as well from the colour as from the 

 dimensions of certain parts of the body appear to be very variable. This is also the 

 case with the specimens enumerated above, but I think, however, that they must be
