[Plates VIII. & IX.] 
POLYZOA (continued). 
Genus Larnacicus*, gen. nov. 
Type, Larnacicus corniger, Busk. (Pl. VIII. fig. 3.) 
_ Membranipora cornigera, Hincks, Hist. Brit. Marine Polyzoa, p. 164, 
pl. xxi. fig. 4, and pl. xxii. fig. 3. 
Differs from Amphiblestrum: 1st, in the avicularia being 
situated in distinct and separate cells from the zocecia (in the 
type species they vary greatly in size: the larger are long, 
ovate, contracted near the middle in the position of the 
complete but easily broken bar; in the smaller the anterior 
portion is loop-shaped and the posterior a mere slit); 2nd, 
in the absence of pore-chambers (at any rate, I have not 
succeeded in seeing any) ; 3rd, in the remarkable character 
of the distal end of the zoccium, which is divided into 
chambers by a transverse and usually one or two vertical 
connecting-bars. These chambers most probably are in con- 
nexion with the ocecium, which is well raised, globose, and 
situated over the chamber just described. There are two or 
three pair of spines, the lower pair forked at their extremity. 
T illustrate the ocecium, which has not hitherto been figured. 
Specimens of this species from 100 fathoms off Shetland, 
and from the Hardanger Fiord, Norway, are in my collection. 
Genus ANTROPORA J}, gen. NOV. 
Type, Antropora (Membranipora) granulifera (Hincks). 
(Pl. VIII. fig. 4.) 
Membranipora granulifera, Hincks, “General History Marine Polyzoa,” 
Ann. & Mag. Nat. Hist. ser. 5, vol. vi. (1880) p. 72, pl. ix. fig. 4. 
Zocecia triangular or subtriangular, but very irregular in 
form. Calcareous portion of the area similar to that of Am- 
* \dpva€, a chest or coffer, in allusion to the structure of the anterior 
part of the zocecium. } : 
+ dvrpov, a cave or hollow, with reference to the hollow in which the 
oral opening lies. ,
