n ATR ACHIA \S FROM WEST AFRICA

snout, is highly suggestive of an Atelopus, and specimens from 

 Togoland have been described by Werner as Atelopus africanus. 

 I have had the skeleton prepared and it shows all the essential 

 characters of a Bufo. Males, and some females to a lesser degree, 

 have small pearl-like excrescences on the sides. A vocal sac is 

 absent. Some specimens are uniformly black: others are more 

 brown, with a pink, reddish-brown, or pale olive lateral band, 

 and with small whitish spots on the lower parts. 



9. Nectophryne afra, Peters. (PL I, fig. 2). 



Fernando Po: Basilè, 400-600 m., Bahia de S. Carlos, 400 m., 

 Musola, 500-700 m. 



French Congo: Fernand-Yaz, N'Kogo. 



As I have already pointed out this little toad varies much in 

 colour and markings. A young specimen from N'Kogo, here 

 figured, is remarkable as being dark purplish brown above, with 

 four curved whitish cross-bands, the first on the snout, the second 

 on the back of the head, from eye to eye: a large whitish spot 

 on the knee and another above the heel. 



Atelophiryrie, g. n. 



Closely allied to Bufo, but first and fourth fingers and toes 

 rudimentary, and fifth toe absent. A very slight rudiment of 

 web between the toes. 



10. Atelophryne minuta, sp. n. (PI. I, fig. 3). 



Snout obtusely pointed, prominent, obliquely truncate, as long 

 as the eye; canthus rostralis angular; loreal region vertical; in- 

 terorbital space broader than the upper eyelid; tympanum hidden. 

 Fingers and toes obtuse; third finger twice as long as second, 

 third toe twice and a half as long as second; subarticular tuber- 

 cles very large, feebly prominent; two obtuse metatarsal tubercles. 

 The tarso-metatarsal articulation reaches the tip of the snout, or 

 between the eye and the tip of the snout. Skin with small smooth 

 warts above, granular beneath; no parotoids. Brown above, with 

 dark and lighter marblings; a dark streak under the canthus ro- 

 stralis, sometimes continued on the temporal region and along 

 the side of the body , with or without a lighter streak above it; 

 lower parts dirty white.
