110 A MONOGRAPH OF THE TERTIARY POLYZOA OE VICTORIA. 



erect in tlu> c(Mitr;il parts, smooth; tliyrostoiuc subcircular, Avitli a conspicuous 

 rounded .sinus in the lower lip ; the margins thick and tumid.

I have i^'real douht whether this may not be really identical with C. costazel. 

 The spi-cimeus ai'e all small. In some of the zooocia the peristome is a little more 

 pi'ominent on each side ; there is, however, no appearance of avicularia in any of 

 the specimens.

or this I have only two or three specimens too imperfect for description or 

 illustration, ])ul still sufficient to leave no doubt of the identification.

Zoarium smaU. Zooecia ovate, distinct at the margins, confused and erect in 

 the central parts ; thyrostome rounded, Avith a distinct narrow sinus in the lower 

 lip ; peristome produced above to form a lofty mucro having a small ovate avicu- 

 larium on the inner aspect at the apex, and rising on each side into a point. 

 Owcium situated Ix'low tlu; thyrostome, projecting, rounded, with a semicircular 

 space in Trout, bouudcd by a distinct border and traversed by converging grooves.

Zoarium massive, lobed, in the specimen figured anvil-shaped. Zoojcia con- 

 I used, indistinct, immersed, surface finely graiuilar ; thyrostome opening straight 

 forwards, arched above, lower lip with a wide sinus, a sharj) internal denticle, on 

 i-acli side ; scattered rounded avicularia, on elevations, interspersed among the 

 zocecia. 



S.P. 



'there are specinu'us of several otlier species of Celle])ora and lSchismo]iora, but 

 in too imperfect a condition for certain identificcition or (U'scription in so difhcult a 

 genus. Among IIkiu are, I believe, C. intermedia (McG.) and C. co)-onopiis 

 (S. Wood).
