CrLtarmp#, Hincks, ‘ Brit. Mar. Polyzoa’; A. W. Waters, Bryozoa, 
Bay of Naples ; Papers on Australian Bryozoa (fifth Report ‘ Brit. Assoc.” 
1884 on Fossil Polyzoa), &c. 
Genus Cellaria, Lamouroua (part) 
= Salicornia, Schweigger; Salicornaria, Owvier; Salicornaria, Busk ; 
Farcimia, Fleming. 
Celaria fistulosa, Linn.. Hincks, ‘Brit. Mar. Pol.’ p. 106, pl. xiii. 
figs. 1-4. Hincks gives 14 recent and 10 fossil synonyms. 
3 sinuosa, Hassall, Hincks, p. 109, pl. xiii. figs. 5-8. 
5 Johnsoni, Busk, Hincks, p. 112, pl. xiii. figs. 9-12. 
The last species: Shetland; Madeira; Algiers. 
Tn the ‘ Challenger Report ’ the family contains the following genera :— 
1. Salicornaria, Cuvier. 
2. Melicerita, Milne-Hdwards. 
Genus 47. Salicornaria, Cuvier. 
‘Zoarium radicate, simple or branched, articulated or continuous ; 
cylindrical, with the cells disposed round an imaginary axis; with or 
without avicularia. When articulated the internodes are connected by 
short straight tubes, or with the intervention of a convoluted knot of 
slender tubules.’—Ohal. Rep. p. 86. | 
In the above Report Mr. Busk has devoted nearly five pages to the 
discussion of moot points of structure in the species of the genus irre- — 
spective of very full details of the new forms in the ‘ Challenger’ | 
material. The group is divided into three sections, which will be alluded 
to presently, and then he remarks that, ‘speaking generally, the species 
of Salicornaria . . . may be grouped into those in which the areolation 
is fundamentally rhomboidal, and those in which it is strictly hexagonal ” 
(op. cit. p. 87). After giving the ‘Challenger’ species I will give the 
list as furnished by Mr. Busk, in which the two sorts of areolation may — 
be studied. It may be well to note that the closer study of the chitinous — 
parts—given by Mr. Busk in the woodcuts—will afford ample and 
interesting details when dealing with the new or even the well-known ~ 
species of this remarkable group. I do not, however, think that the new 
light thrown upon the ‘ Challenger’ species will be lost or neglected in — 
future researches of students of our British and foreign marine polyzoa.
