OX OVfCELLS OF SOME LIC IIEXOPOR^E. 
Lichexopora victoriexsis, nom. uov. (PL XY. fig. 4.) 
Discoporella reticulata, MacGillivray, Trans. Roy. Soc. Viet. vol. xx. 
p. 126, fig. 1 . 
There is already Lichenopora reticulata, since Hagenow described 
a fossil as Defrancia reticulata (Bry. der Maast. Kreide, p. 4 3, 
pi. iv. fig. 3, non 4). Marsson has already shown that the descrip- 
tion refers to fig. 3 and not to 4. It is possible that this may 
have been described under another name, but this is not certain ; 
aud I certainly cannot agree with Dr. Pergens, who would call it 
cliadema , uniting the Defrancia disticha, Hag., D. diadema, Gold., 
and D. reticulata, Hag. 
As Mr. MacGillivray describes it from Victoria, I would suggest 
the name L. victoriensis. 
This is one of those species in which without the ovicellular 
ducts it would be difficult to say whether there was an ovicell or 
not. The central area is covered by the ovicell, the covering of 
which is formed by large raised trabeculae, within which there is 
a smaller reticulation formed by similar trabeculae. There are 
spines with knobs from the walls of the trabeculae, similar to those 
1 described in Lichenopora grignonensis (Ann. Mag. Nat. Hist, 
ser. 5, vol. xx. p. 262, pi. vii. fig. 4). In the present case I have 
only figured a few of these spines, not to complicate the figure 
too much. The spaces between the trabeculae are filled in with 
a perforated cover. Aperture of zooecial tubes about 006 mm. 
wide.

Discotubigera P lineata, MacG. (PI. XV. fig. 5.) 
Diastopora lineata, MacGillivray , Trans. Roy. Soc. Viet. vol. xxi. p. 96, 
pi. iii. fig. 1. 
Liripora lineata, MacG. Cat. Mar. Polyzoa of Viet., Roy. Soc. Viet. 
1887, p. 32. 
Discotubigera lineata, Waters, Ann. Mag. Nat. Hist. ser. 5, vol. xx. 
p. 260, pi. vi. fig. 24. 
I have already (loc. cit.) alluded to the ovicell, but it has never 
been figured, and therefore I add a figure of an ovicell occurring 
near the border of the zoarium. It will be seen that it is of a 
type quite different from that of Lichenopora ; but as yet we are iu 
ignorance concerning the ovicells of Discotubigera and its allies.
