The fishes were caught liv digging a hole through the ice. and lowering a trap

 was made of raliliil -wire, spread over iron liars, sei/ed to hoops uf iron. At either end 

 there was a rone-shaped entrance made of wire. l'v this method as ma.ny as three 

 hundred Hshes were caught from one hole. 



The fishes were all Trematomus ln-rini<'<-liii.** Altogether the species ot Trematodes, 

 three of Echinorhynchi, some larval Kehiiiorhvnclii, larval Xematodes, and (.'estodes.

The seals \vere of three kinds: AVeddell's Seals. Crab-eating Seals, and Sea- 

 Leopards. 



The Weddells Seals (Leptonychotes iri'ilili-lli) were for the most part older than 

 the others and seemed more heavily infected ; they contained at least six species ot 

 ( 'estudes. one Trematode of .special interest, two Nemafodes, and one or two species of 

 Echinorhynchi. An enevsted Eckinorhynchux larva, is shown later to lie the young of
