beneath the apertures. The closed zooecia are sporadic in 
distribution, and are usually closed by a perforated dome- 
shaped cap. Gonocysts as large, tumid areas, formed of 
several zooecia, and haviug two or more apertures.

Diagnosis. 
Eleidae (?) in which the zoarium consists of an erect, branched 
stem. The stem consists of a cylindrical series of long thin 
zooecia, which form a central tube ; surrounded by a layer 
of zooecia composed of the expanded distal ends of the zooecia. 
In the middle part of the stem the zooecia are irregularly 
arranged. The apertures are sube(][ual. 
Type Species. 
Pennipora heyrichii, Hamm. Haastrichtian : Maastricht. 
Affinities. 
This genus is placed by Hamm in his group the Cerioporina, 
but he compares the arrangement of the zooecia to that in his 
Stigmatoporina. In his memoir the genus is placed shortly^- after 
Heteropora^ to which it has a resemblance in that the apertures 
are unequal in size. But in the description of the only species 
Hamm states that the apertures are only slightly unequal in size. 
The structure of the zoarium resembles that in Inversaria, and, sn 
far as can be judged from Hamm’s description, the Bryozoan is 
probably an ally or synonym of Inversaria tuliporacea (Goldf.).^
