796 REPORT OF THE HARVARD AFRICAN EXPEDITION 
one is West African ranging as far east as Kisumu, the other is a Southeast 
African species rarely mentioned in the literature. H. pusillus was omitted from 
Boulenger’s 1910 list of South African reptiles and batrachians and on apply- 
ing his key to these Kisumu or to Noble’s Congo frogs they fall to marmoratus. 
Until someone undertakes a revision of the genus it seems better to record 
our frogs as above rather than add to an already complicated bibliography. 
The total length of these Kisumu specimens is 26 and 28 mm. respectively. 
They differ from the descriptions of pusillus, marmoratus, and from Noble’s 
Congo frogs in that the brownish-orange spots on the back are distinctly raised, 
apart from this, however, they agree structurally with both pusillus and mar- 
moratus. The larger is purplish-brown showing a few dark purple vermiculations 
and numerous dark orange spots on the sides; the smaller is yellowish-brown 
above with numerous purplish, as well as bright orange, spots upon the back. 
Both are white below speckled with orange, and with minute black specks on 
the throat. 
Both hold developing pigmented eggs. In the stomach of one the limbs 
of grasshoppers are recognizable. 
Cacosternum boettgeri (Boulenger) 
1 (M.C.Z.14776) West of Mbarara, Kitende, Uganda. 
This 22 mm. specimen appears to constitute the first published record of 
the occurrence of this little Brevicepitid in Uganda. It agrees very closely with 
examples from the Plat River, Northwestern Transvaal, though possibly a trifle 
slenderer in form. 
Hewitt ! has recently described a race of this toad from Mariannhill, Natal, 
under the name of C. 6. albwenter and states that it occurs in the forest at Gra- 
hamstown, while the typical form with spotted abdomen is found at Grahams- 
town outside the forest. In passing it might be stated that of three specimens 
labelled ‘‘Grahamstown”’ received by exchange from Dr. Boulenger, one (M.C.Z. 
No. 2903) has an immaculate belly but this is not correlated with a more rounded 
snout; in external characters the three specimens appear the same. Our Plat 
River specimens (M.C.Z. Nos. 10791-—2) while possessing mottled abdomens 
lack the black stripe from nostril to eye and from eye to base of fore limb which 
Hewitt states is characteristic of all typical boettger?.
