observations on the habits and modes of collecting the young of these 
and other marine animals, the author has presented many new and valu- 
able contributions to our knowledge of the development of several spe- 
cies of Annelids. Among these are species of Planaria, Spirorbis, Tere- 
bella, Polydora, Nerine, Phyllodoce, and Nareda(?). The latter is com- 
in Annelids. tg work is illustrated by six wood-cut plates, erect |

E. Verritt. (Extracted from Proceedings of the Essex Institute, vols. iv 
and v.)\—This pamphlet has been published in three parts, of which the 
two first have already been noticed in this Journal. Part III contains 
the Madreporaria, illustrated by two plates, one of which includes also 
a few species of Actinide. Three new genera, Pachysammia, Calastrea 
and Cyclopora., are described, and thirty-seven new species. Among the 
more interesting orms are a living Eupsammia, hitherto a tertiary le us, 
three species of Stephanoseris, an Allopora from California, and a 
sy with a figure of the living polyp.

ciety ‘of Natural History, April, 1866.)—This paper is prefaced b 
comparison of the Polyp faunz of the Atlantic and Pacific shores of 
Central America, showing a remarkable contrast—as had been previously 
determined for the ollusca, Crustacea, and other classes, giving addi- 
tional evidence of the improbability of oceanic communication across the 
sthmus in recent geological times. Four new aan of Aleyonaria and 
eight of Madreporaria are described ; also w genus, Stephanocora, 
belonging to the Poritide. All of the pie described species are 
mentioned, with their known cach eer and other observations.
