Orley (29) divides the Nematohelmintlies into the three suborders of 
the Nematentozoa, Rhabditi for nice, and Anguillulidoi ; the first are para- 
sitic, the second intermediate in structure, and the third free-living ; the 
larvae of the first perish unless they enter hosts, the second may or may 
not do so, and the third develop in mould or water. 
Megnin, finding that the anaemia of dogs is apparently duo to three 
species, with the buccal armature of (1) Dochmius trigonocephalus , 
(2) Ancylostoma duodenale , and (3) D. balsami , thinks that they are 
all forms of one species, and that the differences in the form of the 
teeth are probably due to age (Bull. Soc. Z. Fr. vii. pp. 282-289, 1 pi.). 
On the influence of low temperature on Trichina , see Douley & Gibier, 
C. R. xciv. pp. 1683-1686. 
Schulthess (31) gives a detailed description of Ancylostoma , and points 
out that the genital tract, which is always Avell developed, is especially 
so in the female, in a transverse section of which the tube may be cut 
through as many as ten times.

Filaria muscicapce, F. strigis (= Trichina ajjinis, Diesing, e. p.), Stron- 
gylus papillatus (intestine of Otis tarda), S. monodon (gastric walls of 
QZdemia nigra), Trichosoma lalpce (bladder of mole), Agamonematodum 
hospes {Armadillo vulgaris , Vortex lapicida , Vitrina cellaria). 
Of old forms, he figures : Strongylus minutus, Duj., S. polygyrus , Duj.,
