REPTILES AND AMPHIBIANS FROM LIBERIA — LOVERIDGE 129 



the absence of topotypic material of Nieden's frog, the Mount Coffee 

 (p. 785) specimens may still be considered to represent fessmanni, but 

 the frogs from Gbanga and Du River (p. 782) that I thought to be 

 young tessmanni must be considered specifically distinct on account of 

 the less developed webbing on both hand and foot. I take pleasure in 

 naming the new species after its collector, Dr. J. Bequaert, who has 

 done so much to advance our knowledge of African zoology in many 

 fields. 



Type. — M.C.Z. No. 12000, a female from Gbanga, Republic of 

 Liberia, collected by Joseph Bequaert, September 1926. 



Paratopes.— Young 5 (M.C.Z. No. 12001), Gbanga, Liberia (J. 

 Bequaert) ; $ and juv. (M.C.Z. Nos. 12002-3), Plantation No. 3, Du 

 River, Liberia (G. M. Allen) ; $ (U.S.N.M. No. 109051) , Gibi, Liberia 

 (W. M. Mann). 



Diagnosis. — Digits with a mere rudiment of web ; toes with a single 

 joint free of web on the first, second, and third, two joints free on the 

 fourth, a single or only half a joint free on the fifth. 



In contrast the Mount Coffee frog (M.C.Z. No. 15939) has only the 

 first finger with a rudiment of web, the second has one joint free, the 

 third two joints, the fourth one and a half joints; of its toes only the 

 first has a single joint free, the second, third and fifth are webbed to 

 the disks on at least one side, the fourth has one and a half (right) to 

 2 (left) joints free of web. It is a $ of larger size, viz, 50 mm. 



Description. — Vomerine teeth in two small groups between the 

 choanae. Head as broad (or slightly broader than) long; snout 

 roundish, half to two-thirds the diameter of the eye ; interorbital space 

 slightly broader than (or as broad as) an upper eyelid; tympanum 

 two-thirds tlie diameter of the eye; fingers rather long with a mere 

 rudiment of web, their disks as large as the tympanum; toes two- 

 thirds webbed, one joint free of web on the first, second, and third 

 toes, two joints free on fourth, half (or one) joint free on fifth, the 

 disks a little smaller than those on the fingers ; inner metatarsal tuber- 

 cle large, oval, strongly compressed ; the tibiotarsal articulation of the 

 adpressed hind limb reaches the nostril (or eye). Skin of dorsum 

 shagreened and with small scattered warts ; on the throat, belly, and 

 under the thighs, granular; males with a callous pad on the breast 

 in the region of the axilla. 



Coloration. — Above, pale brown, a dark, triangidar, interorbital 

 marking, its apex directed posteriorly and often confluent with a more 

 or less distinct hourglass pattern on the back; a dark line from the 

 eye passes over the tympanum to the base of the forearm (and may be 

 continued on the flank as a series of dashes) ; flanks marbled with 

 brown ; forearm, thighs, and to some extent the foot, crossbarred with 

 dark brown ; from disk of outer finger to elbow, from disk of outer toe
