506 G>'orf/)va Si.veet : 



Host. — Horse : ileum and caecum. 



Locality. — Melbourne, Sept., 1908, per Mr. W. T. Kendall. 

 The existence of this tapeworm has previously been recorded 

 for N.S.W. and Queensland, and possibly for Victoria. Those 

 brought to me represented a very large number found all along 

 the ileum and also in the caecum of a horse which had been 

 killed for dissection. The small intestine is not so common a 

 habitat for this species as the caecum. Mr. Kendall states that 

 tapeworms are " very common " in horses here, but that he has 

 " never known them to produce any characteristic symptoms, 

 and as they are found in nearly all old horses, he is of the 

 opinion that they do little harm." 



No. 2. — Cysticercus pisiformis, Zedei-. 



This simple cystic stage of Taenia serrata, Goeze, has been 

 found in considerable numbers in the rabbits used in the 

 Biological laboratory during 1908, and has also been sent in 

 from numerous other localities, so that it would appear to be 

 widespread in Victoria. 



Host. — Rabbit : all parts of the peritoneum are subject to the 

 presence of these cysts. 



Locality. — General in Victoria. Per Mr. A. Hart (Freezing 

 Works), etc. 



Previously recorded for N.S.W. and Victoria (v. pt. i.. Census.) 



No. 3. — Echinococcus polymorphus, Diesing. 



= Echinococcus huminis. 



= Ecliinococcus multilocidaris. 



= Echinococcus veterinorum, Rud. 

 These cysts forming the asexual generation of Taenia echinu- 

 rficcus, V. Sieb., have been very i)revalent in rabbits in Victoria 

 during 1908, both those brought to the Biological Laboratory, 

 and those used as food, a large number having been sent to me 

 from the Freezing Works. They have been found in almost all 

 of the organs lying in the abdominal cavity, liver, kidney, 

 uterus, etc., in tlie peritoneum and also in the muscles of the 

 body wall or limbs. The complexity and size of the cysts vary 

 greatly witli age, while the cyst wall itself may be very thin, 

 semi-transparent and fragile, or tough and iibrous.
