I have also received from the Veterinary College here the 

 kidney of a horse deformed by two deeply-seated cysts which 

 appear to belong to this species. It is stated by Mr. Kendall 

 to be ver}' rare. 



Host. — Rabbit : abdominal organs generally, per Mr. Dom- 

 brain, June, 1893, and Mr. A. Hart (Freezing Works), July, 

 1908 ; horse kidney, per Mr. W. T. Kendall, Melbourne Veteri- 

 nary College. 



Locality.- — Various in Victoria. 



Previously recorded for Victoria in Man " and Lower ani- 

 mals " (v. part i.. Census). 



No. 4. — Coenui'us serialis (?), IJnill. 



This is repi'esented in this collection by one cyst, 21 mm. 

 long and averaging 18 mm. in diameter. Li the present cyst the 

 scolices are seen to be arranged in groups along 6 nearly radial 

 lines on the inner side of the somewhat fragile cyst-wall. The 

 head of the scolex conforms in general with the characters of 

 Taenia serialis. the hooks varying in number from 27 to 30, and 

 in general shape resembling the typical hooks of this species. 

 In size, however, the hooks of this specimen are much smaller 

 in size — viz., the larger .092 mm. long, and the smaller .OQi mm. 

 (as against .135 and .085 mm. and upwards). 



Host. — Rabbit. 



Locality. — Victoria (?). 



Taenia serialis (?) has been recorded {u-eviously from Aus- 

 tralia but once only, by Cobb, in a dog from N.S.W. The hooks 

 there, however, are larger than the typical ones.
