58 MR. H. B. FANTHAM ON A NEW SPOROZOON. | May 16, 
A. hottentottus, but markedly narrower across the brain-case ; 
and the zygomata less thickened at their posterior base. As a 
result, the two skulls beg of about the same length, the general 
outline was much less broadly triangular. Muzzle and inter- 
orbital region narrow and delicate. 
Outer edge of permanent teeth narrow antero-posteriorly, and 
of milk-teeth broad with conspicuous cusps, as shown in the Plate. 
The anterior premolar triangular, not extended transversely as 
in A. obtusirostris and chrysillus. 
Dimensions of the type, measured in the flesh :—Head and 
body 129 mm.; hind foot 13. 
Skull—ereatest length 28, basal length 22:6; greatest breadth 
across brain-case 16°6; greatest height 12°6; imterorbital breadth 
8; front of i to back of m* 10:5; palate, breadth across 
premolars 8-1. 
An adult female had a head and body length of 118 mm. ; 
ereatest skull length 25:7. 
Hab. Kuysna, 8. Cape Colony. ‘In Forest.” 
Type. Oldmale. Original number 1021. Collected 25 January, 
1905, by C. H. B. Gheats and presented to the British Museum by 
Mr. ©. D. Rudd. Ten specimens examined. 
This handsome little species was not only a very interesting 
discovery in itself, but the fine series of it obtained by 
Mr. Grant, of both sexes and different ages, had enabled 
Mr. Thomas to identify with confidence the milk and permanent 
dentitions of the specimen figured in the plate illustrating his 
paper on the Zululand Mammals collected by Mr. Grant. No 
proper knowledge of the respective characters of the two den- 
titions had hitherto existed. 
My. H. B. Fantham, B.Sc., F.Z.8., exhibited microscopic 
slides of and made remarks upon Lankesterella tritonis, N. Sp., a 
Hemogregarine parasitic in the red blood-corpuscles of a Newt, 
Triton cristatus (Molge cristata). Blackboard sketches were made 
illustrating the life-history of the parasite so far as was known. 
This parasite was found some time ago by the exhibitor while 
working in the Zoological Laboratory, University College, London. 
Afterwards his observations were independently confirmed by 
Dr. A. C. Stevenson. Up to the present the trophozoite and 
schizogonous stages only had been seen, and the sporogony 
pr obably took place in an intermediate host. Schaudinn’s and 
Siegel’s recent observations on the sporogony of allied parasites 
in the lizard and water-tortoise were quoted in support of this 
view, and mention was made of the inaccuracy of Hintze’s account 
of the sporogony of Z. ranarum in the intestine of the frog, 
the cysts therein mentioned probably being Eimerian stages of a 
Coecidian. 
The trophozoites, vermiform in shape, were apparently 5 py to 
6 » in length, and slightly over 1» broad. They became U-shaped
