noeth-italia:n^ beyozoa. 31 



Reuss, in my opinion, was justified in giving it another name ; 

 moreover, " diplostoma " had already been nsed by Philippi. 



Pergens is mistaken in supposing that it has been found in the 

 Vienna Tertiaries, though, as mentioned, the Yal di Lonte material 

 was for a time supposed to come from the Vienna Easin.

There are two incrusting specimens from Montecchio Maggiore ; and 

 the ovate zooecia are in one case arranged in a radiate manner. The 

 peristome is raised, and an avicularium at the side forms X3art of it, 

 just as in Porina duplicata ; but there is no suboral pore, the avicu- 

 larian chamber is larger, and the shape is more distinctly seen from 

 the outside, thus causing greater irregularity of appearance. The 

 ovicells are globular, recumbent, perforated. The oral aperture is, 

 no doubt, nearly round ; but it has not been possible to see the 

 exact shape : probably oligostigma belongs to the ScTiismopora 

 group.

 figs. 12-14 ; Pergens, Eoss. Bryoz. Ton Wola Lu'zanska, p. 72. 



In a specimen from Val di Lonte, not well preserved, the ovicells 

 are broken down, but the Oral apertures are nearly straight below 

 and about 0-15 millim. wide. I have mentioned a subglobular 

 C. pertusa from Aldinga (Quart. Journ. Geol. Soc. vol. xli. p. 305). 

 Marsson (Bryoz. Schreibkreide der Insel Eiigen, p. 101) says that 

 0. lenticulaons, Eeuss, is the Qellepora accuraidata of Hagenow; 

 though, from the description and figures, it is impossible to be sure 

 of this. 



A cylindrical specimen from Montecchio Maggiore also has the 

 pertusa aperture and a suboral avicularium ; but neither is the pre- 

 servation of this satisfactory.

From Brendola this occurs in a disk form ; in Cupularia-foim ; 

 and in fiat pieces which must have been from a larger growth. 



The zooecia are raised and rounded, with the oral aperture slightly 

 coarctate, nearly central, somewhat depressed ; on the right side 

 of many zooecia there is a large triangular avicularium with a bar 

 across. Out of a number of specimens, I have only found one zooe- 

 cium with an avicularium on the left side. Some pieces have an 

 avicularium to almost every cell, others only to one or two zooecia.
