320 Mr. H. J. Carter’s Contributions to our 
In the British Museum there is yet another species of this 
kind, which also came from the same neighbourhood, viz. 
“Van Diemen’s Land” (No. 397), labelled in Dr. Gray’s 
handwriting, 517, Radiella;” but it is not mentioned in 
any of his publications, so that it appears never to have gone 
beyond the MS. form mentioned; whereas Schmidt, in 1870 
(Spongienf. atlantisch. Gebietes, p. 48), published a genus by 
this name, under which two species are described (Taf. iv. 
figs. 6 & 8), viz. Radiella sol and Rf. spinularia, the latter 
identitied by Schmidt himself with Dr. Bowerbank’s Tethya 
spinularia (Mon. B.S. vol. iti. pl. xv. figs. 23-30) ; while 
both species appear to me to belong to Dr. Bowerbank’s genus 
 Polymastia,”’ established in 1866 (op. cit. vol... p. 5). As 
the term “ Radiella,’ therefore, is only in MS., Schmidt’s 
use of it in print must be preferred, and a new one instituted 
for the specimen in the British Museum, which, being totally 
different from Schmidt’s Radiella, while it is closely allied to 
Phycopsis hirsuta, 1 will describe under this generic name as 
follows :— 
Phycopsis fruticulosa, n. sp. (Pl. XIV. fig. 12.) 
Stipitate, bushy, thickly and dichotomously branched from 
a common stem; clothed with bright brown filamentous pro- 
cesses. Branches thick, round, dividing at short intervals so 
as to form a close shrubby mass; diminishing in diameter 
from the stem upwards, ending in thick round points. Axial 
portion or stem not predominating, being only one sixth of 
the length of the filamentous processes in diameter, composed 
of colourless fibre charged with the spicules of the species. 
Filamentous coat consisting of narrow strips of yellowish 
sarcode, about half an inch in length, also charged with the 
spicules of the species, emanating from the circumference of the 
axial portion in a radiating manner (hence, probably, Dr. 
Gray’s MS. name “ Radiella”) upwards and outwards, more 
or less united together at first, but finally terminating by 
division into two or more white or colourless threads, which 
give the surface a filamentous aspect; echinated throughout 
by the projection of the spicules. Filamentous coat longest 
midway between the base of the stem and its branched extre- 
mities; shortest about the base, where the stem is thick and 
hard, as in the foregoing species. Spicule of one form onl 
viz. acerate, curved, smooth, and sharp-pointed at each end, 
like that of the last species, about 35 by 1$-1800ths inch in its 
greatest dimensions (fig. 12). Size of specimen 34 inches high 
by 22 in its greatest horizontal diameter.
