FOSSILS OF NEW SOUTH WALES. 711 
Glendon. 
This very delicate species is quite common at Glendon, and forms fronds several 
inches in extent.

pl. 9, figs. 1, 1 a. 
91. FenesTeLta Gracitis (Dana).—Lax, branchlets extremely slender, dichoto- 
mous with arcuate axils; reticulation somewhat irregular; spaces large, and usually not 
rectangular, three or four times as wide as the branchlets. Under surface of branchlets 
smooth or slightly striate-—Plate 11, fig. 4, part of frond, natural size. 
Glendon. 
This species is near the /. formosa of M’Coy, (Carb. Foss. Ireland, pl. 29, fig. 2,) but 
the spaces are larger, 
Nore.—Plate 11, figs. 5, 5 a, represent another Fenestella ; but we forbear describing 
from our imperfect specimen. The spaces and branchlets are minute as in the F. fossula, 
but the under surface is marked irregularly by a few undulating lines, and the branchlets 
diverge more frequently through the intercalation of new branchlets.

the form and direction of the columns; 6 a, size and closeness of columns; 0, outer 
surface, natural size ; c, outline of cells of same enlarged. 
Wollongong Point, District of Illawarra. 
The specimens of this species from [Illawarra are occasionally six inches in diameter, 
and have a spheroidal form. They usually occur as the interior of spherical concretions, 
like most of the fossils of Wollongong Point. The size of the columns is about a fourth 
of a line; or, as they lie in the specimen, there are 30 in the breadth of half an inch; 
they separate rather easily, and are singularly regular in form, with few constrictions 
from irregular growth, and these commonly very slight and in concentric lines, which 
sometimes give a specimen the appearance of being made of successive tiers of columns.

93. CurTeres TaSMANIENSIS (Lonsdale) Dana,—Plate 11, fig. 7, natural size; 7 a, 
surface enlarged, Fig. 8, a flattened specimen ; 8 @, surface of same enlarged. 
Harper’s Hill. 
Lonsdale’s specimens are cited as from Mount Wellington, Mount Dromedary, Norfolk 
Plains, Van Diemen’s Land. Those of Harper’s Hill have a pearly white exterior, and 
are imbedded in the dark greenish argillaceous sandstone of that place. The branches 
are few, about half an inch in diameter. The columns are of uneven diameter, and are 
very slender, there being 35 or 38 to a breadth of half an inch. ‘The apertures of the 
cells are oval; the interstices are either broad, or are quite narrow; the granules of the 
surface are irregularly placed, and often wanting between some of the cells. One spe- 
cimen, (fig. 8,) is much flattened out by compression, as was the case with one men- 
tioned by Lonsdale.

South Wales, p. 262, pl. 8, fig. 2.
