Tho Tt'icltina previously discovered hy Bahody encysted in the walls of ll>o 
stomach and intestine of rats (and differing specifically from T. spiralis, Owen, 
found at the same time encysted in the muscles of the same rats), Bakody (1) 
has again found in the same places in rats and hens, without the contem- 
poraneous occurrence of the Trichina of the muscular tissue. The cysts and 
parasite are figured and described in detail. 
Gnathostoma [Chir acanthus) hispidtim, sp, n., Fedclienko, 1. c. [p. 427], 
pp. 7-11, fig. 15, in ventricular coats of wild hog, Tchardara (Central Asia), 
and of tho domestic hog, Hungary. 
Anytdllula radicicola, sp. n., Greeff (5), from root-galls in various plants. 
Filaria anlimgcc : cf. Am. Nat. vi. p. 6G0. 
Ascaris cristata, sp. n., Linstow (7). Very common in the intestine of the 
pike ; in a younger state in cysts externally on the intestine of the bream. 
Ascaris dentata was found encysted, more or less abundantly, in the liver 
of every examined specimen of Cohitis harhatula ; in its sexual state it is 
found, much more rarely, in Acerina cernua : Grimm (6). 
A. mystax. A fourth instance of the occurrence in man of this parasite 
of the dog and cat is recorded by Heller (SB. Soc. Erlangen, iv. p. 71), who 
inclines to the belief that A. lumhricoides is introduced directly into the 
human body. In one subject 18 young specimens were found, from 2*75 mm. 
to 13 mm. long.
