On Rana Fuscigula and B. Angolensis. 
135 
Habitat. — Namaqmaland, Cape Province, Orange Free State, Western 
Transvaal. 
A smaller race inhabits Nyassaland and Massailand. 
The record of this species from Sierra Leone (Giinther, Cat., p. 132 ; 
Bouleng., Cat., p. 50) is the result of a misunderstanding. The two 
specimens in the British Museum labelled as from that part of Africa 
belong to two distinct species — R. fuscigtila and R. occipitalis. I had over- 
looked or misread a MS. label on the jar containing these frogs; it bears 
the following indication, which explains everything : " Rana fuscigula, 
Cape. Ditto, Sierra Leone." The latter locality evidently applies to the 
R. occipitalis, the other specimen being from the Cape of G-ood Hope. 
Rana angolensis. — Vomerine teeth in short or moderately long transverse 
or oblique series between the choanae, rarely extending a little beyond the 
level of the posterior borders of the latter. 
Head as long as broad or a little longer than broad, very rarely slightly 
broader than long, rather less depressed than in the preceding species ; snout 
usually obtusely acuminate and projecting beyond the mouth, longer than 
the eye, rarely not longer ; canthus rostralis obtuse ; loreal region less 
oblique than in the preceding, feebly concave ; nostril equidistant from the 
eye and the tip of the snout, or nearer the former ; the distance between the 
nostrils greater than the interorbital width, which is much less than that of 
the upper eyelid ; tympanum very distinct, I- to f the diameter of the eye 
and 1^ to 3 times its distance from the latter. 
Fingers obtusely pointed, first and second equal or, very rarely, first 
slightly longer than second, third as long as or a little longer or a little shorter 
than the snout ; subarticular tubercles rather small and feebly prominent. 
Hind limb variable in length, but usually very long ; the tibio-tarsal 
articulation reaching the tip at the snout or beyond, the heels strongly over- 
lapping ; tibia It} to 1| times in length from snout to vent, usually as long 
as or a little longer than the fore limb, rarely a little shorter, usually as lo/Ug 
as or a little longer than the foot. Toes obtusely pointed, about f webbed, 
rarely f , 2 or 3 phalanges of fourth free ; subarticular tubercles small and 
feebly prominent : a more or less distinct fold along the inner side of the 
tarsus ; inner metatarsal tubercle oval or elliptical, ^ to |- the length of the 
inner toe ; no outer tubercle. 
Upper parts smooth or with small tubercles, usually with more or less 
prominent, interrupted, glandular, longitudinal folds on the back, 6 or 8 in 
number, of which a pair beginning from the upper eyelids may be more 
developed than the others ; a curved fold from the eye to the shoulder. 
Lower parts smooth, thighs granular near the vent. 
Coloration very variable. Brown or olive above, usually with dark olive 
or black spots, which may be large or small, disposed irregularly on the back
