1907.] BATRACHIANS AND REPTILES. 481 



mavblecl with dark brown, with a Y-shaped white marking on 

 each side ; belly white. Male with two external vocal sacs, 

 opening by a slit on each side of the throat. 



From snout to vent 48 millim. 



Two males and one female, found bi-eeding in a rain-pool at 

 Beira in February. 



This species is very closely related to R. ornata Peters, from 

 E. Africa, and R. ornatissima Bocage, from Angola. It differs 

 from the former in the shorter web between the toes, from the 

 latter in the much smaller size, in the shorter and less pointed 

 snout, and in the shorter hind limbs. The white markings in 

 front of the eye and under the throat are very similar in the three 

 species. Another very close ally of R. ruddi is R. moeruensis 

 Blgr., from Lake Mweru, which differs in the longer fii'st finger, 

 the longer hind limbs, the very prominent dorso-lateral glandular 

 fold, and the coloration.

A widely distributed species, known from the Soudan (from 

 west to east). West Africa from the Senegal to the Congo, and 

 Central and East Africa {R. hravana Peters t, R. ouhangiensis 

 Mocquard). 



R. galamensis is closely related to the Indian R. malabarica 

 D. & B., and surprisingly resembles the Central- American R. god- 

 mani Gthr. The male has an external vocal sac on each side of 

 the throat and a large flat gland on the front side of the arm 

 (humerus), as in the Burmese R. granulosa And., R. kumeralis 

 Blgr., and R. oatesi Blgr. 



I avail myself of this opportunity to point out that the Frog 

 named by me R. elegans, which had been previously confounded 

 with the West- African R. alhilahris Hallow., is identical with 

 R. guentheri Blgr., and must therefore be erased from the list of 

 African species. 



t Specimens of Jl. nutti Blgr. have been erroneously referred to B. bravana by 

 Tornier.
