 United States Fish Commissioner for 1872-1873. In discussing the 

 sturgeon fishery Mr. Milner says they frequently have raw sores 

 upon them due to the lampreys. He thinks the lampreys eat the 

 slime of the sturgeon.

 figer Bericht. Archiv f. Anatomie, Physiologie und wissentschaft- 

 liche Medicin (Miiller's Archiv)., 1856, pp. 323-339. First scienti- 

 fic account of the transformation of larval lampreys into adult Pe- 

 troniyzon. Up to this time the larvae had been placed in a separate 

 genus {Amtnoccetes branchialis). But little has been added to 

 Miiller's account of the more obvious changes from the egg to the 

 adult lamprey. He reported the presence of an 8th branchiopore in 

 the embryo (" Am Halsebefiiiden sich 8 Visceral spalten, deren vor- 

 derste, schon durch ihre Richtung verschieden, sich bald wieder 

 schliesst" \ The discovery of an 8th gill opening in the embryo 

 is ascribed to Huxlej' by Shipley ('87, p. 349).

 from a solid cord along the ventral side of the dorsal aorta in the 

 larva. Compare Schneider, ('79, p. 94).

 Arch. f. mikr. Anat. XVIII, pp. 1-121. As eggs of Petroniyzon are 

 all at the same stage of development, the author thinks the lam- 

 preys die after spawning (p. 47) thus agreeing with A. Miiller ('56, 

 P- 334)-
