the water-shrews (Sorex fodiens), but, so far as I am aware, 

 nothing has been done in connection with the parasites of the 

 Matroecelidina, of the Banxrangs (Tupaina), or of the Tanecs 

 (Centites) and their allies. The entozoa of the star-nosed and 

 shrew moles of North America (Condylura and Scalops) also 

 deserve attention. From the last-named genus (8. canadensis) 

 Prof. Leidy obtained a single male spiroptera. It occupied the 

 stomach and was only half an inch in length.

Notwithstanding the importance of the entozoa of this large 

 section of mammals, I must deal with them very summarily, 

 emphasising my remarks on the parasites of the dog and cat. 

 Only a few of the ectozoa can be noticed. 



The bears are much infested by nematodes, the species being 

 Ascaris transfuga and Spiroptera (Gongylonema) contorta of 

 Molin. The latter is found in the oesophagus. Immature 

 round worms have also been found in cysts. These were 

 erroneously described as cestodes by Zeder and Gmelin. The 

 bear, however, is very liable to be infested by genuine Cysticerci. 

 Ketzius found them in the muscles, and they are described as 

 examples of the ordinary hog-measle. The museum attached
