REPTILES AND AMPHIBIANS FROM LAKE REGION 799 
Hyperolius pleurotaenius (Boulenger) 
33 (M.C.Z. 14700-25) Burunga, B.C. 
43 (M.C.Z. 14726-50) Foot of Mt. Mikeno, B.C. 14. iii. 27. 
One Burunga female frog measures 33 mm., the type was 31 mm. The 
fine Mikeno series ranges in size from 11 to 31 mm. frogs. The smallest, 11-12 
mm., are pallid with dusky specklings above, a light, speckle-free, band runs from 
the nostril along the canthus, then above the eye to the flanks, anteriorly it is 
bordered above and below by a dusky band formed by a concentration of the 
dorsal specklings. 
Medium-sized frogs of 21 mm. are somewhat darker, have lost the light 
canthal and lateral line, but retain a single dark line in these regions, the back 
is mottled with dusky spots or vermiculations, the limbs also to a lesser degree. 
The feet show pinkish a year after preservation. 
Individuals from 22 to 25 mm. are purplish-brown with a well-defined dark 
canthal-lateral band and usually (eleven out of nineteen specimens) exhibit 
dark dorsal spots or vermiculations. 
Frogs from 28 to 31 mm. are usually purplish or reddish brown though 
four out of nineteen are cream-colored, all exhibit the dark canthal-rostral 
band while four of the nineteen, though not the pallid ones, show darker spots 
or vermiculations on the back. 
These agree structurally with frogs.from Medje, Belgian Congo, referred 
by Noble to this species, except for a slight spinosity of the skin in the region of 
the snout, probably brought out by a difference in methods of preservation. 
They agree also with Medje specimens in lacking light dorsal spots, but differ 
from them in showing no light canthal-lateral band in the adults. Undoubt- 
edly the whole series represent one species though to avoid confusion the above 
color notes are based on the Mikeno series only, one Burunga specimen lacks 
even the dark canthal-lateral line. 
The large Burunga female held well-developed, pigmented eggs when caught 
on March 22nd, 1927; her stomach contained beetle elytra. 
Hyperolius ? pusillus (Cope), ? marmoratus Rapp 
Crumenifera pusilla Cope, 1862, Proc. Acad. Nat. Sci. Phila., p. 343. 
2 (M.C.Z. 14697-8) Kisumu, Kenya Colony. 
In referring these two female frogs to pusillus we wish to record only their 
specific identity with Congo specimens which Noble ! considered to be pusillus; 
they have also been compared with one of the three Kisumu frogs which 
Angel? referred to Rappia guttulata Ginther. All are one species. If Cope 
was correct in giving the type locality of his species as Umvoti, Natal (it was 
changed to ‘‘Umvoti, West Africa”? by Boulenger in 1882, though we know 
of no other Umvoti than the Natal locality) then the distribution of the species 
leads us to suppose that two distinct frogs are being recorded under this name,
