794 REPORT OF THE HARVARD AFRICAN EXPEDITION 
Relations. Very near to A. minutus of which form it is probably an offshoot. Distinguished by 
its large size, very distinct tympanum, thicker fingers and toes, and the slightly dilated tips of both 
fingers and toes. 
Description. Habit moderate. Tongue with a median conical papilla, as broad as long (or 
longer than broad). Snout rounded, projecting slightly beyond the mouth, shorter than the di- 
ameter of orbit; nostril midway between end of snout and orbit; interorbital space considerably 
broader than the upper eyelid; tympanum very distinct. Fingers moderate, first shorter than the 
second which is slightly shorter than the fourth, third about twice the length of first, unwebbed. 
Toes moderate, about one third webbed except the fourth where the web extends forward as a very 
narrow margin to the second joint from the end, tips of fingers and toes slightly dilated or thickened, 
subarticular tubercles well developed, an inner and an outer metatarsal as well as a tarsal tubercle 
all of which are very small, the tarsal being about as far from the inner metatarsal as the latter is 
from the outer, a slight skinfold from the tarsal to the inner metatarsal tubercle. The tibio- 
tarsal articulation of the adpressed hind limb reaches to the nostril (to eye or nostril, or between, 
in the paratype series). Skin above and below smooth. 
Coloration. Above, uniform brown. Below, white, mottled and vermiculated with dusky 
brown on the throat and chest; belly and thighs immaculate, edge of lower lip, soles of hands and 
feet plumbeus. The paratype series show much variation, twelve have a moderately narrow choco- 
late brown vertebral stripe from snout to anus. The young are usually paler brown showing some 
barring on the limbs. Below, the throat and underparts may be almost immaculate, or with a few 
large spots or so covered with minute speckling as to appear dusky. 
Measurements. Snout to vent 22 mm. 
Length of head 7 mm. 
Breadth of head 7mm. 
Diameter of orbit 2mm. 
Length of tibia 11.5 mm. 
Length of foot 15 mm, 
Length of 4th toe 7 mm. 
Paratype series range from 12 to 25 mm. all of the latter size being females. 
Material. The possibilities of identity with moorit, feae, ogoensis, schubotzi or rowxti has been 
carefully gone into, and close comparison made with specimens of minutus from various East 
African localities. 
Breeding. Ovules large (1.3 mm. in type ¢) in all adult females. 
Hyperolius guttulatus Giinther 
1 (M.C.Z. 14699) Uvira, B.C. 
We are indebted to Dr. Gaston de Witte for the identification of this 34 mm. 
adult male frog. H. guttulatus was described by Giinther in 1858 from speci- 
mens of unknown habitat. Noble, in his 1924 check list of African amphibia, 
says ‘“‘Known only from the type specimens.” Dr. Bequaert’s capture is, 
therefore, of considerable interest. 
The frog agrees perfectly with the somewhat meagre structural descerip- 
tion but differs considerably in coloration, for instead of being ‘‘finely white 
dotted” it has a series of five large light, dark-edged, spots along the vertebral 
line, the foremost being the largest and covering the interorbital space. There 
is also a light, dark-edged above, lateral band commencing on the upper eye- 
lid. The band is, however, very indefinite, merging into the white of the under 
side below and more or less broken up on one flank. On the tibiae, which are 
light colored, there is a dark longitudinal stripe followed by two transverse 
bars of the same color; three or four dark spots are present on each fore arm.
