14. HOKNEBA A8PERULA (EeuSs). (PL III. fig. 7.) 



Hornera asperula^ Eeuss, Bry. von Crosaro, p. 284, pi. xxxv. 

 figs. 8, 9. 



Hornera d'Achiardi^ Heiiss, op. cit. p. 285, pi. xxxv. fig. 12. 



This is a very small species, and in specimens from Brendola 

 numerous short branches grow at right angles to the main branch. 

 There is no serial arrangement of the zooecia as in H. concatenata^ 

 and in the younger ends there is a longitudinal ribbing as figured in 

 H. d'AcJiiardi, whereas the older ^Dart is plain.

For synonyms, see Jelly, Catal. of Marine Bryozoa, p. 115, and add : 

 ■ Hornera trabecularis, Beuss, Bry. von Crosaro, p. 284, pi. xxxv. 

 fig. 7. 



H. traheeularis of E-euss represents the growing end of H frondi- 

 culata, and Pergens has already indicated that they are synonymous. 

 There are also stouter basal portions from Brendola. 



Loc. Widely distributed in the Eocene, Miocene, and Pliocene of 

 Europe, and in the Australian Tertiaries ; Wanganui, New Zealand ;

16. CEASS0H0E2fEEA AEBUSCULA (EeUSS). (PI. III. figS. 5, 6.) 



Ceriopora arhuscidum, Eeuss, Foss. Polyp. Wien. Tert. p. 34, 

 pi. V. figs. 12, 13. 



I had not seen this species when I described Crassohornera 

 luaipuJcerensis (Quart. Journ. Geol. Soc. vol. xliii. p. 349), but, as I 

 then said, they are very closely allied. In the Montecchio Maggiore 

 specimens the entire surface is covered with shallow pits, with a 

 pore in the centre, those on the dorsal surface being the smaller. 

 The ovicell, which is dorsal, extends over nearly the whole width of 

 the zoarium, and the pits on its surface are more angular than those 

 on the zooecia. 



The zoarium starts with a flat base, and, after growing vertically 

 for a very short distance, grows horizontally, with numerous short 

 branches on each side. The position of the ovicell indicates that we 

 have to do with more than a basal growth, and shows relationship 

 with Hornera, nor is it by any means certain that a second genus is 

 required. 



Manzoni (Bri. foss. del Mioc. d'Austr. ed Ung. p. 18, pi. xi. 

 fig. 43) says this is probably the same as Ceriopora globulus, C. cylin- 

 drica, &c., but with this opinion I am unable to agree. There is also 

 Ceriopora arbusculus, Eoemer, from Sollingen, which, though named 

 independently, is very similar.
