Linstow records t^irongylus ardicus Cobb from the ear of the 

 beluga, and PseudaUm alaius from the Kustachian tnl)e and tlie 

 pharynx. 



In the ahmentary tract of the (higon^^ trematodes occur in 

 the f2:ut and the ca^'um. In the small intestine some very large 

 worm masses were observed, whose composition could not be fully 

 determined. Tn addition, a species of Ascaris has \o\\^ been 

 known from the digestive tract and numerous specimens of this 

 were also found in the glands of the stoniacli. Ir is Asrans 

 halicoris Owen, also wrongly called \srun. <linjunis iirandt. 

 Whether the Ascarid seen by Steller in the i-hytina is identical 

 with that found in the dugong cannot now be determined. Two 

 endoparasites are also described from the manatee: a nematode, 

 UetcrocheUus hinicaius Diesing, and a trematode, Amphfsfomim 

 fabaceum Diesing (von f^instow, 78, 'SO). (Iiaj)man ('To, p. 

 456) found the large intestine of his American maiuitee filled 

 with the latter.
