INSEOTIVORA 295 



Westwood has obtained several allied forms of Hipposcida 

 (of the genus StreUa), also from bats. As regards the true 

 Arachnidans (mites and ticks), Van Beneden enumerates Ixodes 

 Uvidus, Van Ben., Pteroptus vespertilionis and P. arcuatus, 

 Koch, Otonissus aurantiacus and Cerathophyllus octactenus, both 

 of Kolenati, and Caris elliptica.

The entozoa of insectivorous mammals, though sufficiently 

 numerous, are not important practically. The common hedge- 

 hog (Erinaceus europtsus) is infested by four flukes (Distoma 

 pusillum, D. trigonocephalum, D. caudatum, D. linguceforme) , 

 and also by three thorn-headed worms (Echinorhynchus napce- 

 formis, E. amphipachus, and E. major). Two tapeworms are 

 also known (Taenia compacta and T. tripunctata) . More atten- 

 tion has been paid to the round worms. A species of strongyle 

 (8. striatus) infests the lungs, the male being readily distin- 

 guished by its nearly round hood. A second species of stron- 

 gyle has been mentioned by Diesing, but it is more than 

 doubtful. The lungs are also infested by a small trichosome 

 (Eucoleus tenuis of Dujardin) ; another species of the genus 

 (Trich. exiguum) infesting the stomach and small intestine. As 

 the Trichina spiralis has been repeatedly reared by myself and 

 others in the hedgehog, the little flesh-worm must also be 

 noticed in this place. Physaloptera clausa occupies the 

 stomach, and a minute Ascaris (A. pusilla) is found in cysts of 

 the peritoneum. According to Wedl, the intestine of the 

 Egyptian hedgehog (Erinaceus auritus) is infested by another
