NOETH-ITALIAN BETOZOA. 19 



The ovicelligeroiis zooecia, instead of being parallel with the axis 

 of the zoarium, turn at right angles to it, and are much raised in 

 their distal end, with the ovicell somewhat recumbent behind the 

 peristome. In the form of the aperture and the ovicells this is 

 closely related to L. nodulifera (Ess.). PI. II. fig. 16 is the L.- 

 microdonta-ioTJR, with the row of fine linear pores round the border, 

 and the separating ridges running in to the aperture, with the avicu- 

 laria and ovicells resembling those of more typical L. bisulca. 



I do not feel at all sure from the description that Koschinsky had 

 the same thing before him.

The aperture is slightly rounded below, and sometimes the thick 

 calcareous growth of the divisional walls extends round the aperture, 

 but sometimes it only occurs above the aperture. In some cells the 

 proximal end is raised, and in one colony there are ovicells behind 

 the aperture of such zooecia. In one case there seems to be a raised 

 avicularium at the border of the zooecium, but I cannot speak vpith 

 certainty about it. 



This seems to have nothing in common with the other Peritei- 

 chismce of Koschinsky ; and the genus appears based on the nature 

 of the calcification rather than upon characters of much value ; in 

 fact some have an opesial opening, but in others, as in nodidifera, 

 the aperture has, no donbt, been closed by an operculum.

On a specimen from Brendola there is a raised round ovicell above 

 the aperture, perforated with pores somewhat more crowded than 

 those on the front of the zooecium. In some cases there is an avicu- 

 larium at one side below the aperture, and then it looks like an early 

 stage of Cellepora proteiformis, Ess.
