508 G. R. Vine—Carboniferous Polyzoa. 
cal forms, for the Glauconome marginata, Munst., in Goldfuss’s 
Petrefac. of Germany, is given by Hincks as a synonym of Cellarta 
fistulosa, Linn. It was, however, established by Goldfuss, and after- 
wards revised by Lonsdale. M‘Coy,’ improving upon Phillips’s* 
poor description, does not make any reference to the number of 
pores between the branchlets. In his later work he defines the 
genus more minutely thus :— 
“Corallum composed of a narrow central stem, with numerous 
. & 
pinnules, or lateral branches uwnconneeted with each other: both 
stems and branches have two rows of cells on one face, which 
is usually carinated between them, carina in some species tubercu- 
lated ; opposite face striated.” * ; 
In a paper read at the Nat. Hist. Soc. Glasgow, the Messrs. Young 
describe several new species of Glauconome.

In describing G. elegantula Mr. Etheridge defines and criticizes the 
genus Glauconome with especial reference to the Acanthocladia.° 
1875. Hyphasmopora, R. Etheridge, jun.® 
The generic and specific characters of this new provisional genus 
are well described by Mr. Etheridge in the paper referred to. There 
is only one species—H. Buskii, and I am glad that after submitting 
the specimens to Mr. Busk, Mr. Etheridge followed his own judg- 
ment and established a new genus, rather than adopt the suggestion 
of Mr. Busk, “That the above resembled the genus Vincularia, 
Defrance ”—adding afterwards, “It is probably the type of a new 
genus, perhaps allied to the latter.” This beautiful species is found 
in several localities of Scotland, but I have found it in Yorkshire, 
and also in N. Wales. It cannot, however, be considered a common’ 
form anywhere. 
1850. Sulcoretepora, D’Orbigny. 
This genus has been accepted by Morris (Uatal.) and by the Messrs. 
Young, of Glasgow, for certain species of Carboniferous Polyzoa. 
Morris gives the above date, but the Messrs. Young in their paper? 
say, “The genus Sulcoretepora was formed by D’Orbigny in 1847, 
with the following definition: Cells in furrows on one side of simple 
depressed branches.”
