diflfereiice which I cjiu detect is that the iudicatioii of a keel ou the 

 dorsal scales is slightly more pioiiounced in the eastern ones. The 

 number of scale rows are also somewhat variable in the latter as I have 

 counted 20 rows iilmost as often as 10. In addition I may say that in 

 the youngest specimen the rostral is but slightly prominent, hardly 

 more so thiin in C. rhombeatus. 



II. BATRACHIA. 



ECAUDATA. 



Phrynomantis bifasciata (.S.aiith). 



Three specimens ( [J. S. National Museum, Nos. li01i;3-201ir)) collected 

 by (^hauler at the Tana River. They belong to Boulenger's variety A 

 (Cat. Batr. Sal. Br. Mus., p. 173) with the modification that the lateral 

 bauds do not commence on the upper eyelids but -between the nostrils. 

 It is to be noted that Dr. (1. A. Fischer has already collected this species 

 at Wito on the Tana (Peters, lleise Mossamb., Zool., Amph., p. 172). 



Bufo regularis Reuss. 



Eight specimens (IT. S. National Museum, Nos. 20107, 20116-20122) 

 collected by Mr. Chanler on the Tana Eiver, and two (Nos. 16751-16752) 

 by Dr. Abbott at Kilima-Njaro. 



In all the specimens the vertical light line above the vShoulder is 

 plainly indicated, no matter how different the coloration may other- 

 wise be. All are likewise marked with dark rose-color on the i)osterior 

 aspect of the thighs, while in some of the younger individuals the rose- 

 color also pervades the back in a varying degree. In the young spec- 

 imens the tympanum is comiiaratively smaller than in the adults; but 

 the first finger is in all distinctly longer than the second. 



Hyperolius ciiictiventris (!opk. 



The only specimen sent home by Mr. Chanler, who collected it ou the 

 Tana Eiver (U. S. National Museum, No. 20493), belongs undoubtedly 

 to the species collectively named as above, but I nm not by any means 

 convinced that all the names referred to by Boulenger (Cat. Batr. Sal, 

 Br. Mus., 1882, p. 126) under the present s])ecies are in reality uncon- 

 ditional synonyms. 



For that reason it may be useful to make a few notes concerning 

 structure and coloration of Mr. Chanler's specimens,
