cyf or between tlie eyo and tin? tip of the snout ; til)ia Jiljout 

 half the length of head and body. Skin shagreened above,

From snout to vent 42 mm. 



A single specimen from Et'ulen ; also several from Cape 

 St. John and the llio BcMiito District (Spanish West Afiica), 

 which I had previously confounded with young II. rufuii. 

 This species stands very near //. ru/us, Reichen., diflfering 

 only in the rather less depressed head and in the presence of a, 

 conical tubercle on the heel. 



Iltjiamhates cuhito-alhus. 



A'^omerine teeth in two small groups on a level with the 

 posterior border of the choana'. Head broader than long, 

 strongly depressed ; snout rounded, as long as the eye ; inter- 

 orbital space broader than the ujjper eyelid ; tympanum very 

 distinct, two thirds the diameter of the eye. Fingers rather 

 short, with a mere rudiment of web; toes half webbed, three 

 phalanges of fourth and two of fifth free ; disks well developed ; 

 subarticular tubercles strong; inner metatarsal tubercle 

 moderate, oval, feebly prominent. The tibio-tarsal articu- 

 lation reaches the eye. -Skin smooth above, granular beneath. 

 Green above, with a fine black areolation ; a white line 

 bordering the upper lip, another above the anal region ; 

 elbow, knee, and iieel with a large round white spot ; sides 

 of thighs purplish brown; lower parts white. 



From snout to vent 33 mm. 



Two specimens from Zima. The British Museum has 

 since received frotn Dr. C Christy two further specimens 

 obtained by him in Unyoro, east of Lake Albert, along with 

 examples of two other frogs common in Cameroon, liana 

 albilaOris, Hallow., and Phrynobutrachus pUcatus^ Gthr. 



In coloration this new species resembles very strikingly 

 //. notatusj Peters, which is the young of //. ru/us, lieiciien., 

 and which differs in a more slender form and a more develope I 

 web between the fingers and toes. It is more nearly allied 

 to //. VannutiUii, lilgr., likewise obtainetl in Unyoro by 

 Dr. Christy, but differs Irom it in the broader interorbital 

 space.
