58 .^tR. H. B. FANTHAM OX A XEW SPOROZOOX. [May 1 6, 



A. hottentottiis, but markedly narrower across the brain-case ; 

 i\Yid the zygomata less thickened at their posterior base. As a 

 i-esult, the two skulls being 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 ti-ansversely as 

 in A. ohtusirostris and chrysillus. 



Dimensions of the type, measured in the flesh : — Head and 

 body 129 mm. ; hind foot 13. 



Skull — greatest length 28, basal length 22'6 ; greatest breadth 

 across brain-case 16'6 ;• greatest height 12'6 ; interorbital breadth 

 8 ; front of i^ to back of m~ lO'S ; palate, breadth across 

 premolars 8'1. 



An adult female had a head and body length of 118 mm.; 

 greatest skull length 25"7. 



Hah. Knysna, S..Oape Colony. "In Forest." 



Tyjie. Old male. Original number 1021. Collected 25 January, 

 1905, by C. H. B. Grant, and presented to the British Museum by 

 Mr. C. D. Budd. Ten specimens .examined. 



This handsome little species was not only a veiy interesting- 

 discovery in itself, but the fine series of it obtained by 

 Ml-. Gi'ant, of both sexes and diflerent 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 ZuluLxnd Mammals collected by Mr. Grant. No 

 pi-oper knowledge of the respective charactei^s of the two den- 

 titions had hitherto existed. 



~Slv. H. B. Fantham, B.Sc, F.Z.S., exhibited microscopic 

 slides of and made remarks upon Lanhesterella tritonis, n, sp., a 

 Hfemogregarine 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 Avas 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. Uj) to the present the trophozoite and 

 schizogonous stages only had been seen, and the sporogony 

 probably took place in an intermediate host. Schaudinn's and 

 Siegel's i-ecent observations on the sporogony of allied parasites 

 in the lizard and water-tortoise were quoted in suppoi't of this 

 view, and mention was made of the inaccuiacy of Hintze's account 

 of the sporogony of L. ranarimn in the intestine of the frog, 

 the cysts therein mentioned probably being Eimeiaan stages of a 

 Coccidian. 



The trophozoites, vermiform in shape, were apparently 5 ^ to 

 6 ^ in length, and slightly over 1 yj broad. They became U-shaped
