Sporozoa. Coccidium Rivolta, a close ally of the C. 

 Perforans of the dog is found in the intestinal epithelium of the 

 cat enclosed in a membrane with double contour. Free in the 

 intestine it has an oval outline and in water it passes through the 

 same successive developmental stages as the C. Perforans. Fick 

 describes a larger Coccidium (80 to 100 i*. long by 70 to 90//. wide) 

 as abundant in the intestinal villi of the cat and assisting in the 

 absorption of fatty substances. 



Infusoria. Lamblia Intestinalis which is common in sheep 

 and dog is also found in the cat. 



Cestodes. Taenia CrassicoUis. Thick-necked T. This 

 is an armed taenia with large head and usually thicker neck, and 

 from 5 to 20 inches long. Its rounded probosis is furnished with 

 a double row of 26 to 52 booklets, the handle being longer than 

 the blade. Segmentation begins at once in the thick neck, and 

 they become square 15 or 20 centimetres behind the head: — 4 to 

 5 mm. across. The ripe segments measure about 8 to 10 mm. 

 long, by 5 to 6 mm. wide. Ova circular 31 to 37 /x in diameter. 



Habitat. The small intestine of the cat where the head is 

 usually fixed by its booklets to the mucosa. 



Cysticercus Fasciolaris. The Band or Pipe like C. The 

 cystic or larval stage of the T. CrassicoUis is found in the liver of 

 rats, mice and other small rodents (Norway rat, water rat, vole). 

 It is remarkable for its long narrow pipe-like form, coiled up in a 

 cyst the formation of which has been caused by its presence. It 

 ends in front in a small pea-shaped vesicle having an opening 

 showing invagination of the head and is prolonged behind by a 

 distinct chain of segments, devoid of sexual organs. The cyst
