The same author has also published observations (Z. c.) on A scaris

drius hiaticuld), Strongylus nodularis (between the stomachal membranes 
of Fulica atrd), Dorijlcemus stagnalis, D. (pi. i. figs. 17-22), Tylenchus fili- 
formis, Btl. (pi. ii. fig. 23), Trilobus gracilis, Bst. (pi. ii. figs. 26 & 27). 
Calyptonema,^2iV., is probably founded upon specimens changing the 
skin, during which process the interior chitinous covering of the oeso- 
phagus and the supplemental spine are also thrown off. To Cobbold 
(2), are due observations on Ascaris simplex {delphini) Rud. [intestine^of 
Platanista gangetica\ A. leptura, R. (intestine and cloaca of Testudo 
elongata), Oxyuris obesa, Dies. (pi. xxi. figs. 16-19, from the Capybara ?),

Db Man (28) has described 60 species of free terrestrial species and 
(29) 18 maritime from Naples. Of the Dutch, several are from brackish 
soil, suggesting a descent of the terrestrial from marine species. Figures
