34 LARS GABRIEL ANDERSSON, BATRACHIANS. 



Phrynomantis bifasciata Smith. 



Blgr., Cat. Batr. Sal., p. 172. 



8 species at the Forest reserve at the Limuru-road near Nairobi, April 9th, 

 1911; in waterpools in the grass. 



Professor Lönnberg writes in his diary about them: »When returning över a 

 meadow I heard a frog croaking with a sound different from others, someting like 

 a rather strong 'errrr'. I went to the spöt and perceived a black töad with large 

 bright minium-red spöts on the back, and as I saw låter on, round white spöts below. 

 I caught one and then another; they appeared rather slow. Then we heard again 

 the same sound a little bit further on and I went there and picked up several. In 

 one the spöts were only påle salmon coloured, in all others bright minium red.» 



The species was at first known from South Africa, where it has been found at 

 many places. At least on the eastern coast it goes rather far to the North. Peters 

 and Stejneger have before stated it from British East Africa (Tana-river) and 

 Tornier from several localities in German East Africa.

I specimen, Nairobi, April 1911, 21 mm. in length. 



This species was hitherto with certainty only known from South Africa. In 

 Proc. Zool. Soc. 1895, p. 540, Boulenger mentions a specimen from Western Somali- 

 land, b ut lie appears to be doubtful about the correctness of this find. He says: »The 

 occurrence so far north of this species, originally described from Caffraria, is surprising. 

 Yet I have little doubt the determination is correct. » When it is stated now that 

 the species lives in British East Africa its occurrence in Somaliland does not appear 

 so stränge as before. Probably, it is distributed över the South, and middle East 

 Africa, although it has been overlooked on account of its small size and possibly of 

 its resemblance with the small Arthroleptis-sipecies. 



The specimen is a female, distended by o va. 



Bufo regularis Reuss. 



Blgr., Cat. Batr. Sal., p. 298. 



1 specimen from Escarpment Jan. 1911; 55 mm. in length. 



1 specimen from Meru borna, 72 mm. in length, Jan. 30 th 1911. »Small showers 

 of rain had probably made them leave their hiding places.» 



3 specimens from Mombasa; April l6 Ul 1911; 90, 74, 73 mm. in length. (J 1 and 

 $ in copula.) 



9 small specimens (12 mm.); Nairobi, April 1911.
