The paper also contains numerical data as to the relative frequency 
of each of these methods, and the author promises more in the future. 
The circulatory system of lungless salamanders is compared with 
that of salamanders having lungs by Bethge (Zeitsch. Wiss. Zool., 
LXIII, 680, 1898), who discusses the question of the seat of respira- 
tion in the lungless forms. He reaches the conclusion that the 
mouth, pharyngeal cavity, and integument participate in respiration 
to an essential extent. He thus is at variance with Marcacci and 
Camerano, who believe that cutaneous respiration is of little con- 
sequence. 
The “cellules musculo-glandulaires ” of the body wall of Owenia 
are reéxamined by Ogneff (Biol. Centralb., XIX, February, 1899), 
who concludes that the structures described by Gilson do not exist. 
The peritoneal lining of the body cavity is closely adherent to the 
muscles of the body wall, but the elements do not differ from those 
in allied forms. 
The endothelium of the heart in bony fishes, according to the recent 
studies of B. Noldeki (Zeitsch. Wiss. Zool, LXV, 1889), is, at least in 
part, of entodermal origin, but it is impossible to decide whether it all 
has that origin. 
The eyes of annelids form the subject of the fifth part of R. 
Hesse’s paper upon the organs for the recognition of light in the 
lower vertebrates (Zeitsch. Wiss. Zool, LXV, 1899). Structural 
details of a large number of forms, as well as of physiological obser- 
vations, are given. 
New cestodes are described by F. Zschokke (Zeitsch. Wiss. Zool., 
LXV, 1899) from various marsupials. The paper contains a revi- 
sion of the species of Beortia and Linstowia 7. g. 
An interesting report on the “ Extent and Condition of the Alewife 
Fisheries of the United States in 1896” has been prepared by H. M. 
Smith, and published in the Report of the United States Fish Commis- 
sion for 1898. Notwithstanding the increase of catch from about 
45,000,000 pounds in 1880 to about 62,000,000 pounds in 1896, the 
values of the catches have decreased; that of 1880 was placed at 
$526,000, while the catch of 1896, though one-third as large again, 
was worth only a little over $459,000.
