Villot (38) suppresses the order Gordiacea (von Siebold), places Mermis 
and Sphcerularia with the Nematoids, and forms the new sub-order 
Gordii for Gordius^ which he places at the head of the Nematohelminthes. 
Ghatin (32) finds that in muscular trichinosis the sarcolemma takes no 
part in the formation of the cyst, which is rather formed from the inter- 
fascicular connective tissue. 
Chatin (28) would regard the larval form of Bilharzia heematohia as 
being more of a scolex than a proscolex ; the amoebiform bodies or 
sarcode spherules are looked upon as young gemmae. 
Attention is directed to Megnin’s paper on Trichina (34).
