RANA DELALANDU (Dam6ril and Bibron) 



A single example from a swampy water hole at Mukwese on June 

 6, 1926. 



PHRYNOBATRACHUS NATALENSIS (Smith) 



Fifteen specimens from a swampy water hole at Mukwese on June 

 6, 1926. 



CHIROMANTIS PETERSH Boalenger 



Six examples were found squatting on aloes, manyara, maize leaves, 

 a post, and in an empty box at Dodoma. Another was taken at 

 Mukwese. As they were found during the dry months, from May to 

 August, apparently they do not aestivate or disappear as C. xerampe- 

 lina appears to do. 



The length of the frogs in this series ranges from 30 to 65 mm. 



I should be inclined to call the loreal region "more or less concave " 

 in all these specimens; in the largest it takes the form of a groove. 

 In most of them the interorbital space equals the width of the upper 

 eyelid, but in one it is less than the width of the upper eyelid. With- 

 out actual comparison with the type of C. Tcachowskii Nikolsky from 

 Abyssinia it is impossible to say how far they overlap. In the larg- 

 est specimen the snout is longer than the greatest orbital diameter; 

 the nostril is a little nearer the end of the snout than it is to the eye. 

 The tibio-tarsal articulation of the adpressed hind limb hardly reaches 

 the ear in the biggest frog, obviously a matter of growth, as in the 

 smallest examples it reaches well forward on the eye and in individuals- 

 intermediate in size it falls between the two extremes.
