on the tibiae of all except 21, and it is noticeable that it is only lacking 

 in young ones except for No. 49311, which is an adult female measur- 

 ing 55 mm.; as this line is not present in any of the specimens of 

 R. oxyrhynchus it is of some slight diagnostic assistance 



The whole series agree in having the interorbital space narrower, 

 or equal to, the upper eyelid; this precludes their being referred to 

 R. venusta Werner, which is said to have the interorbital space 

 broader than the upper eyelid and the head broader than in mas- 

 careniensis, a species with which it appears to agree in all other 

 respects. 



RANA MASCARENIENSIS variety

My object in isolating this individual, a 45-mm. breeding female, 

 from the rest of its series is to draw attention to the several points in 

 which it differs from the rest of the series. It need not be supposed 

 that it is anything else but a mutant of mascareniensis. Besides its 

 most unusual coloration the principal differences between it and the 

 rest of the series are (l) the interorbital space is much broader than 

 the upper eyelid, 3.25 and 2.25 mm. respectively; (2) only two basal 

 joints of the second, third, fourth, and fifth toes webbed, whereas in 

 the fifth the rest of the series have three basal joints webbed; (3) 

 dorsal glandular folds very indistinct though the dorso-lateral pair 

 are strongly marked. An examination of the large series of mas- 

 careniensis in the Museum of Comparative Zoology shows that all 

 of these characters may occur in otherwise typical frogs. It might 

 be added that a cotype of mascareniensis has the interorbital space 

 slightly wider than the upper eyelid.

Through the courtesy of Monsieur Angel I have been able to exam- 

 ine one of the frogs (P. M. 24.14) from Kilimanjaro, which he referred 

 to R. fasciata of South Africa. It measures 46 mm. and agrees essen- 

 tially with a frog of the same length from Phillipshof, Usambara 

 Mountains, Tanganyika Territory, which I consider identical with 

 Lonnberg's merumontana. The distinguishing features of the East
