ANOPLURORUM BRITANNIJE. 35 



large fleshy pulvillus ; unguis very long, curved, slender, and 

 pitchy. Length 1 to 1|. 



This species is found in great numbers on Swine, but it 

 does not appear so generally spread as might be expected 

 from the dirty habits of the animals. It most frequently 

 occurs on those fresh imported from the Sister Isle. It was 

 many months before I could obtain a single example. I 

 had applied to both farmers and pig butchers, neither of 

 whom seemed to approve of the idea which I had conceived, 

 of their pigs being lousy, but referred me to those of the 

 Emerald Isle as being sure to gratify my wishes (forget- 

 ting, I suspect, that the Irish pigs come to this market to 

 meet English buyers). I accordingly visited a colony just 

 arrived, where I most certainly met with a ready supply 

 but here they were confined almost entirely to lean animals, 

 and wherever I found a pig fat or healthy no game were 

 to be seen. In walking this species uses the claw and 

 tibial tooth with great facility (which act as finger and 

 thumb), in taking hold of a single hair ; the male is much 

 smaller, with the abdomen shorter, sub-orbicular, and the 

 segments lobate; the Egg or Nit is f of a line in length, of 

 a cream colour, and elegantly chagreened, oblong and 

 slightly acuminated, surrounded by a lid, which, when the 

 young insect is ready to emerge, splits circularly, or as a 

 Botanist would say, has a circumcisiledehiscence. 



In addition to the above the following species enumerated 

 by different authors, have been detected on the continent 

 of Europe, and as the animals of which they are the para- 

 sites are also indigenous to Great Britain, it is most 

 probable they will eventually be .added to our Fauna. To 

 obtain these I have used every exertion without success ;
