542 THE INVERTEBRATA 



the adult are borne on prominences which may be called limbs, live 

 in other mammals, chiefly herbivorous. The eggs are* passed out of 

 the host, the larvae climb on to plants and are eaten by hares or 

 rabbits ; they traverse the wall of the gut and encyst in other tissues, 

 often the liver. After a period of growth they wander once more 

 through the body ; they may at this stage be eaten by the second host 

 and after wandering through the body reach the nasal passages. The 

 larvae do resemble certain parasitic mites (Fig. 371 A) and for that 

 reason the group has been classed with the arachnids.
