 pi. viii. fig. 12. 



A cylindrical zoarium from. Montecchio Maggiore, with the zooecia 

 distinct, with broad radial grooves round the border, and a raised 

 suboral pore, would seem to be the L. eoccentrica of Eeuss ; but 

 so many species have been described with similar zooecia that no 

 doubt there are many synonyms. The specimen from Montecchio 

 Maggiore has large spatulate vicarious avicularia.

This is an extremely interesting species on account of the peculiar 

 bar across the aperture. 



Zoarium in the Eschara-form ; branches small, compressed, with 

 the zooecia of the two layers opposite. Zooecia elongate, the upper 

 end slightly projecting, and a row of large pores down each side of 

 the zooecium. In the central cells these rows are near together, but 

 in the outer zooecia there is a considerable space between them. 

 About the middle of the oral aperture on each side there is a pore, 

 and in many cases a bar across, as figured by Stoliczka in his 

 Escharifora ornatissima (Bryoz. von Latdorf, p. 86, pi. ii. fig,. 7), but 

 the shape of the zooecia in that species is hexagonal. 



Eeuss in his second paper figures his E. syringopora with the oral 

 pores lower than the aperture ; and sometimes when the aperture 

 is somewhat broken down it has this appearance. 



There are sometimes also other large pores on various parts of 

 the surface, usually one about halfway down, and these may be 

 avicularian. 



In some specimens there are " closures " over the aperture, and 

 these have a tubule in the centre similar to those of so many 

 Diastoporce^ &c. This is at a higher level than the operculum. 



It is abundant at all the stations.
