482 MR. G. A. BOULENGER ON SOUTH-AFRICAN [May 28, 



15, Phrynobatrachus natalensis a. Smith. 



Ooguno, Beira. 



This widely distributed Frog varies remarkabl}^ in its markings. 

 as do the other species of the same genus. A few specimens 

 from Beira are represented on PI. XXII., figs. 2-5, to iUustrate 

 this feature. 



** 16. Arthroleptis avhytii Blgr. 



Beira. 



Previously known from British Central Africa. 



*17. Rappia MARMORA ta Rapp. 

 Beira. 



*18. Rappia cinctiventris Cope. 

 Beira. 



*19. Cassina senegalensis D. & B. 



Illovo. 



The single small specimen, a male, has the elongate oval gular 

 disk of C senegalensis and the distinct web at the base of the 

 toes of C. wealii. I now feel very doubtful aa to the specific 

 validity of C wealii. 



REPTILIA. 



Chelonia. 



1 . HoMOPUS AREOLATUS Thunb. 

 Knysna. 



2. CiNiXYS BELLiANA Gray. 



Beira. Several shells of adults and one young in spirit. 



I have previously t taken exception to Dr. Siebenrock's separa- 

 tion J of C nogueyi Lataste, as a distinct species, and my view 

 is further confirmed by the series of specimens from Beira. The 

 adults (shells only) have the black radiating streaks on the cara- 

 pace, and the extent of the suture between the anal shields varies 

 considerably, as may be seen from the annexed fig'ure (text- fig. 140) 

 representing the hind lobe of the plastron in two adult females, 

 showing two extreme types in the series sent by Mr. Grant. 

 Although the fore limb has five claws in the specimens from 

 Mashonaland § and Zululand examined by me, the young from 

 Beira has only four, and would therefore be refei"able to C nogtiepi. 



**3. Sternoth^rus nigricans Donnd. 



Beira. Two shells, measuring 110 and 77 millim. respectively.

§ I now regard Momopus darlingi Blgr. as based on a youn^ of this species.
