SOME PARASITES FROM CEYLON. 47 



develop further, because the whole animal — as so often happens 

 in the case of Trichina spiralis — becomes calcified. Some obser- 

 vers think that under happier circumstances the sickle-shaped 

 spores become amoeboid and wandering into neighbouring muscle- 

 cells re-start the infection, but the matter is not clear, and a still 

 greater mystery surrounds the first entrance of the parasite into 

 its host.

In his recent revision* of the Amphistomidae Montic. — a 

 family name he replaces by Paramphistomidae — Fischoeder de- 

 scribes amongst the genus Paramphistomufn (= Amphistoma, 

 Rud.) a new species P. hathycotyle found in a Bos kerahau brought 

 from Ceylon to the Zoological Gardens at Konigsberg. Dr. Willey 

 has sent me a considerable collection of parasites which belong to 

 the same species. These were taken from the stomach of Cervus 

 axis, the spotted deer, shot at Weligatta.t 



I have figured the outlines of several specimens, from which 

 it will be seen that the various diameters of the body vary 

 considerably.
