Moll . Ill 
Several species of Polyzoa , new or hitherto only known from the Shet- 
land coasts or in the American seas, have also been found in the Medi- 
terranean or on the South-west coasts of Europe by the dredgings on 
board the ‘ Travailleur ’ ; Alphonse Milne-Edwarde, Ann. N. H. (5) ix.

Two papers by A. W. Waters may be mentioned here, of which the 
first is “ On Fossil Chilostomatous Dryozoa from Mount Gambier, 
South Australia,” J. G. Soc. xxxviii. pp. 257-276, pis. vii.-ix., and the 
second, l. c. pp. 502-513, pi. xxii., is “ On Chilostomatous Bryozoa from 
Bairnsdale (Gippsland).” 127 species are noticed, 52 of which are now 
found also living, three fourths of them in Australia ; 31 are considered to 
be identical with European tertiary species. Abstract in Ann. N. H. (5) 
x. pp. 67 & 175. The author calls attention to the frequency with which 
the Australian Polyzoa exhibit different modes of growth.

Rhahdozoum, g. n. Zoarium erect, phytoid, composed of numerous 
celliferous shoots, held together by a ramified stem made up of bundles 
of radical fibres given off from the inferior portion of the shoots ; cellife- 
rous shoots consisting of a cylindrical bi- or tri-furcate stem, which gives 
origin to the radical fibres and also to erect chitinous roods, on the 
summits of which are borne two or three similar stems, more or less 
dichotomously divided ; zooecia pyriform, ranged in linear series round 
an imaginary axis, so as to form cylindrical stems, each cell rising from
