3. On a Mode of Reproduction in the Inferior Animals; by J. P. 
van Benepen,* (Acad. Sci. Bru sii rom the Institut, No. 718.)— 
The close affinity between the three groups of minute polyps, Cam- 
panularia, Tubularia, and Bataie Ae, is well known. In the first two 
groups, the species produce a medusa-shaped young; van Beneden has 
s rv 
and Sertularia cupressina, of the Brussels coast. He thus concludes 
from his study. 
The verre Campanularide, and the Medusee, and perhaps the 
Sertularide, ~~ through the same phases of development. From the 
egg proceeds a ciliated larve; this larve multiplies by buds and stolons, 
and so produces a compound group or zoophyte. ‘Then some portion 
of this common mass or colony, becomes the seat of a peculiar kind of 
reproduction—a reproduction by “* scission ;” in the Medusee the sirobile 
form is produced ; while in the polyps ovarian sacs are formed contain- 
erations sometimes of one, and sometimes of the other exclusively ; 
that is, we may have medusas giving birth to medusas without going 
through the form of a polyp, and polyps producing polyps which have

multiply in the same manner as those aggregated in chains. But th is 
is not so. The former produce buds, the others eggs. The Salpa
