Leptopelis boulengeri (Werner, 1898)
This species is named for George Albert Boulenger (October 19, 1858 – November 23, 1937), a Belgian-British zoologist who identified over 2000 new animal species, including fish, reptiles and amphibians.
The following is translated from the original description by Werner (1898):
In alcohol the green outlines became purple, they are framed in yellow.There is a cross-band between the eyes, a large triangle on the back with the point facing forward; the limbs are banded in the same color. A pure white patch under the eye. Flanks spotted black, underside white color.
Skin on the upper side shagreened.
I call this fine variety for the author, which he first described; Boulenger describes quite agree with all of my present copy of such "with symmetrical dark markings viz. a cross line between the eyes, and a large triangular spot on the middle of the back." The muzzle is quite long in this form, 1 1 / 3 eye diameter; the skin over the tympanum very clearly shagreened.
