REPTILES AND AMPHIBIANS FROM LIBERIA 183 
Hyperolius concolor (Hallowell). 
2 ex. (M.C.Z. 12021-2) Plantation No. 3, Du River. 
These are topotypes, as the species was originally described from Liberia. 
Hyperolius puncticulatus (Pfeffer) 
1 ex. (M.C.Z. 12016) Gbanga, Liberia. 
1 ex. (M.C.Z. 12017) Paiata, Liberia. 
Originally described from Zanzibar, subsequently reported from Tanganyika 
Territory, these examples appear to be absolutely specifically identical with the 
specimens from Morogoro, one of which is figured by Miss Procter (P.Z.5. 
1920, p. 415). The above specimens give a fresh extension of its range. 
Hyperolius platyceps (Boulenger) 
1 ex. (M.C.Z. 12023) Du River. 
Compared with a topotype from Benito River, Gaboon, received in exchange 
from the British Museum, the striking dorsal marking is remarkably similar 
though in the Liberian frog its outline is a little more regular except posteriorly 
where two offshoots of the broad dorsal line unite with the coloring of the flanks. 
The original description states, ‘‘Outer fingers one-fourth webbed”’ but in both 
these specimens they are one-third webbed, again ‘‘toes two-thirds webbed” is a 
little misleading as the third and fifth toes are webbed to the discs in both speci- 
mens, the fourth toe is webbed to the second joint from the disc. While the 
topotype agrees with the type in that the tibio-tarsal articulation reaches the 
eye, in the Liberian frog it falls far short, only reaching the forearm. 
Hyperolius festivus Barbour and Loveridge. 
Hyperolius festivus Barbour and Loveridge, 1927, Proc. New Engl. Zodél. Club, x, p. 17. 
Type, no. 12018 Museum of Comparative Zodlogy, female, from Firestone Plantation No. 3, 
Du River, Liberia, collected by G. M. Allen, July, 1926. Three examples (M.C.Z., nos. 12018- 
12020), Firestone Plantation No. 3, Du River. 
Description. — Head almost as broad as the body, broader than long; snout rounded, equal 
in length to only half the diameter of the eye, the profile of the tip vertical, canthus rostralis distinct; 
loreal region concave; the distance of the nostril to the end of the snout contained twice in its 
distance from the eye; interorbital space twice as broad as upper eyelid; some granules at corners 
of mouth; tympanum hidden. Outer fingers one half webbed, third and fifth toes webbed to the 
dises and to base of last joint from the discal joint on the fourth toe. Tuibio-tarsal articulation of 
the adpressed hind limb reaches the eye (between eye and snout in half grown paratype); heels 
overlapping when the folded legs are held at right angles to the body; breadth of tibia contained 
four and a half times in its length; length of tibia contained exactly twice in length of head 
and body. Subarticular tubercles very flat; outer metatarsal tubercle on base of fifth finger long, 
rounded, not very conspicuous. Skin smooth above, granular on belly and posterior aspect of 
thighs. 
Coloration. — Above rich brown, from snout to insertion of fore limb black, a black cross- 
band between the eyes extends to the middle of the back in a rather Arthroleptis-like vertebral 
marking, a lunar band across the back well in advance of hind limbs, some black, brown and white 
mottlings on sides. Incomplete bars and blotches on hind limbs; thighs, under side of tibia and 
portions of feet which are concealed when at rest, bright rose-red. Below, except for the white- 
mottled brown edges of the lips, pure white. 
Measurements. — Snout to vent, 28; length of head, 8.5; breadth of head, 10; diameter of 
orbit, 3.5; length of tibia, 14; length of feet, 20; length of fourth toe, 12 mm.
