Hab. In the adult form this species has been observed in Anas Boschas 

 by Bloch, Goeze, Zeder and La Valette; in A.fuligula and A. clan- 

 gula by Mehlis ; in the last named and in A. Penelope by Bellingham ; 

 in A. moschata by Dujardin; in A. Tadorna and A. Cygnus by Crep- 

 lin, also in the latter by Bellingham, as well as in A. Olor and Podi- 

 ceps cristatus ; in Carlo Cormoranus by Wedl ; in Ardea Nycticoraw 

 and A. Grus by Bremser ; in Ardea pavonia by Diesing; and in A. 

 Gardeni by Natterer in Brazil ; it has also been observed in Ardea 

 comata, Carbo pygmaus, Podicepa minor, in Anas Marila, A.Nyroca, 

 A. strepera, A.ferina, A. clypeata, and A. Anser. 



In the young state (if Pagenstecher's view of the identity of this form 

 with Distoma echinattim be correct) it has been seen by La Valette in 

 Fringilla domestica, F. montana, and Columba domestica, also in Lepus 

 Cimiculus (!) and Anas Boschas. 



The larval condition has been noticed in Paludina vivipara, and P. 

 achatina, Planorbis corneas, and Lymnceus stagnalis.
