and that it is Eana cyanophhictis, and not R. tigrina that has this 

 habit. Lieut. Flower says : — " "With regard to the frog Jtana cyatw- 

 phlyctis which jumps oAer the surface of the water .... I never 

 saw Sana tigrina do so. When disturbed on the bank, it always 

 takes a plunge into the water head foremost, and goes straight to 

 the bottom, but i?. cyanophhjctis jumps, alighting on the surface on 

 all fours, and then goes on again, sometimes making a dozen leaps 

 before it finally goes under the surface. Also it will jump out of 

 the water in the middle of a pond, and leap along the surface in a 

 wonderful manner, finally jumping out on the land." 



Colonel Terbury also observed the same habit in the Aden frogs, 

 but he seems to think that it is confined to the younger individuals, 

 as will be seen from the following note extracted from his field- 

 book : — " These frogs were in great abundance in the bed of the 

 stream at Haithalhim. The small ones were everyw-here and were 

 frequently seen leaping along the surface of the water in the 

 manner so often seen in Indaa and Ceylon. The big ones were 

 seen hiding in the deep pools or else lying with their noses out 

 of water among the giant reeds in six or eight inches of water. 

 In either case they required searching for, and, when found, 

 catching — a by no means easy matter. I never recollect seing a 

 big fellow bound along the surface of the water, and can quite 

 understand how such a method of progression is unsuited to their 



size."

These specimens agree in every respect with those from Suakin 

 on which I founded the species, except that the horny induration 

 on the swelling of the snout is absent, and in some specimens 

 recently collected by me at Suakin it is also wanting. It must, 

 therefore, not be regarded as a persistent character, until more 

 information is obtained as to its true nature. 



Mr. Matschie has recorded the occurrence oiBufo a>-a6zctts,Eupp., 

 at Aden, but it is just possible that it may prove to be B. pentoni.

This is the first notice of the occurrence of this Toad at Aden, 

 but Mr. Boulenger has recorded it from Muscat, and the B. viridis, 

 var. oj-tfntaZts, Werner\ from the latter locality may possibly prove 

 to be the same species. The following is a description of the 

 tadpole of this Toad : — 



The length of the body is about four sixths the length of the 

 tail, and its breadth almost three fifths of its own length. The 

 depth of the tail is about one fourth of its length. The nostrils 

 are situated about equally distant from the snout and the eyes ; and 

 the interval between them is about one half the distance between
