kindly compared the Sagalla frog with the type and finds them 

 generically distinct. He also says that there are examples of H. 

 marmoratus from Beira in the British Museum with which the Sagalla 

 frog is comparable as to coloring. (Mount Sagalla). 



2. Three prominent white (black-edged) longitudinal bands; the 

 vertebral from nostrils to anus; the lateral from the posterior supra- 

 ocular regions to the flanks; the broader bands between are chocolate 

 color; limbs white except for numerous chocolate-colored blotches 

 or streaks (Albertville) or limbs yellowish with minute brown speck- 

 ling (Nyanza). 



3. Nos. 63369-72 are slaty-black above with three streaks, as in 2, 

 but very narrow; consequently, the intermediate areas are broader, 

 and instead of being immaculate are spotted or steaked or broken 

 up posteriorly. In No. 63535 this tendency results in the whole upper 

 surface of the body and limbs being vermiculated white and black. 

 All agree in having conspicuous, irregular, white-edged, black spots 

 on the throat, while the throats of the Albertville and Nyanza frog& 

 are immaculate. (Elizabeth ville.) 



4. No. 57522 represents a further stage in which the vermicula- 

 tions of the upper surface having become interrupted they have 

 formed irregular shaped blotches. The throat is spotted like those 

 of the Elizabethville frogs, though less distinctly. It has been 

 labeled H. viridiflavus , but the webbing of the toes precludes the idea 

 of its being referable to that species. (Uganda.) 



HYPEROLIUS SYMETRICUS (Mocquard) 



Rappia symetrica Mocquard, 1902, Bull. Mus. Hist. Nat., vol. 8, p. 408. (Athi 

 River, Kenya Colony.)

The diameter of the orbit is equal to or rather greater than the 

 distance between the anterior border of the eye and the nostril; a 

 translation of the original description would read "snout shorty 

 equal to the horizontal diameter of the eye". Apart from this these 

 frogs agree precisely with the structural description of the holotvpe 

 of symetricus. The few tubercles, which Mocquard suggested were 

 of little significance, are present or almost absent; they reach their 

 maximum development in the Wambugu frog. 



In coloration the first four listed above are apparently brown, like 

 the type ; the last two are buffy gray and indistinguishable from mar- 

 moratus of the same shade except that one has the T-shaped interocular 

 marking of the type as have also two others, it appears to be lacking 

 in the two smaller specimens, but may be obscured by the rust with 

 which they are stained.
