it borders the nostril ; but it may be doubted if this is of specific import- 
ance (cp. Oedura). As regards the snout character it is intermediate 
between typical ocellatus and serval. The nasorostral character is not 
given. The colour markings are of the same general type as serval. 
P. amoenus Wern. — This is placed by Dr. Werner near mariquensis. 
The characters are : snout 1 \ times as long as the eye, nasorostrals 
separated, subdigital lamellae 5-6 ; five dark crossbands on the back, a 
dark spot on the side of the snout over both lips and another one on the 
lower lip just beneath the eye. The colour pattern is distinct enough, 
but in its structural characters it is difficult to see anything specifically 
distinct from ocellatus ; the pattern of purcelli, “ pale-brownish above 
with darker marblings or vermicular spots which may form more or less 
regular crossbands”, connects together typical ocellatus and amoenus. 
Dr. Werner describes the rostral shield as twice as broad as Ions in 
amoenus, and Mr. Boulenger says of ocellatus, “'rostral not or but slightly 
broader than deep ; this is a character which presumably varies with 
the shape of the head”. 
Hemidactylus mabouia Mor. de Jon. — Bushman Mine, S. Rhodesia 
(Bro. J. H. Power). 
Agama . — This genus is evidently in a very confused state. Dr. 
Werner regards both distanti Boul. and brachyura Boul. as local races of 
hispida Lin. ; Dr. Gough considered that distanti is only a variety of 
hispida (see these Annals, Vol. I, p. 183) ; Mr. Boulenger maintains both 
as distinct species. Our material seems to show that brachyura Boul. 
is distinct from hispida proper, but approaches distanti, this latter form 
being, however, a geographical variety of hispida. Whatever view be 
taken it is desirable to make use of the names for distribution studies. 
In my opinion the following records require further investigation i hispida, 
distanti, and aculeata from Kroonstad (Boulenger) j I think it likely that 
the two former records refer to only one species. The same authority 
records hispida from Durban and distanti from Kowie; if these species 
are really distinct it is remarkable that the species characteristic of the 
Cape Peninsula (i.e. hispida) should occur at Durban, whilst the high 
plateau form inhabits Kowie. Werner records hispida from Steinkopf, 
Mafeking, and the Kalahari, but qualifies this by saying that the Steinkopf 
example approaches brachyura and the Kalahari form distanti. Roux 
recorded brachyura from Steinkopf, and presumably he was dealing with 
the same species as Werner. As Dr. Roux has remarked, the records go to 
show that hispida sens, strict, belongs to the southern part of Cape Province 
(western half), whilst the form: distanti belongs particularly to the Trans- 
vaal, (and Tree State), and brachyura belongs to northern Cape Province 
and Namaqualand. It is regrettable that Mr. Boulenger has completely 
united aculeata and armata. No doubt they are merely the extreme 
forms of the same species, but they appear to have a geographical 
significance, and the two forms have the same relationship to each other 
as hispida and distanti. Dr. Werner had already shown that the specific 
distinction between the two forms could not be maintained, but all hie 
records from S. Hereroland, Kalahari, and German South-West Africa are 
referred to aculeata proper, although one of his Hereroland examples
