. & L. echidnae (D’ A. W.Thompson) from the intestine of Echidna 
hystrix. 
4° L. Semoni Zsch. from the intestine of Perameles obesula. 
| The somewhat remarkable distribution of this entozoon which 
is found in Monotremes and Marsupials in Australia and in Guinea 
Fowl in the Soudan will probably in the fulure be shown to be 
connected with the habit, common to all these hosts, of eating 
Insects. 
The genus Linstowia belongs to the sub- family Anoplocephalinae 
R. BL. of the family Tæniadæ Ludw. The sub-family includes eight 
genera which as a rule are found in Ruminants, Apes and Mono- 
tremes and Marsupials, indeed the Cestodes of the last two orders 
are as far as is known, exclusively Anocephaline. The nearest ally 
to Linstowia is thought by Zschokke to be the genus Bertia KR. BI. 
of Rodents, Apes and Marsupials. 
3. — LarvaL Tapeworm from Serval (Felis serval) (pl. VIE, fe. 3-8). 
The label on the bottle containing fragments of this animal 
bears the legend « parasitie Worms found in fatty tissue beneath 
skin of Serval », the cork has the additional words « Gebel Ahmed 
Aga » inscribed on it. 
The fragments were some dozen, and three helene were found 
amongst them. Two of these were attached to lengthy bodies, the 
longer 45e» long, the third had but a body of 1m in length. The 
remaining fragments came from the hinder end of the body. 
Some of them, cut in section, showed large spaces due to the great 
extension of the water-vascular system at this end of the body. 
The head has much the outline and shape of a cobra with its 
hood expanded. The rostellum forms a slight anterior extension 
and this is followed immediatly by a very broad flattened neck 
which is more definitely ringed than any other part of the body. 
There are some twenty-five more or less of these rings which are 
purely superficial and correspond in no way with proglottides and 
then the neck narrows slightly and passes into what may be 
termed the body. The widest of the rings made by the superticial 
grooving is some twenty times as wide as it is long, and the 
middie region and sides are thicker than the inlervening area, 
hence il appears as though two very shallow depressions separated 
the cdges from the centre.
