NORTH ITALIAN BRYOZOA. " 161 



17. Stomatopora major ( Johnston). 



Por synonyms, see Waters, Quart. Journ. Geol. Soc. vol. xliii. 

 (1887) p. 342. 



A specimen from Yal di Lonte would seem to be this species, and 

 I believe that the JDiastoj)ora ecJiinata, Eeuss, Poss. Polyp. Wien. 

 Tert. p. o2, pi. vii. figs. 14, 15, and Alecto echinata, Manzoni, Bri. foss. 

 del Mioc. d'Austr. ed Ung. p. 16, pi. xiv. fig. 57, are also this species. 



The zooecia have an internal diameter of about 0*15 mm. 



18. Pavotubigera plabellata (d'Orbigny). 

 Pavotubigeo'ciflahellata, d'Orb., Pal. Pranc. p. 767, pi. 752. figs. 4- 



8 ; Waters, Quart. Journ. Geol. Soc. vol. xl. (1884) p. 691. 



There are some specimens with the point of origin excentric, 

 just as figured by d'Orbigny, while in some the colonies are almost 

 discoid, and others again are semicircular ; this last is probably a 

 younger form and has been described by Peuss as Defrancia climi- 

 diata. It would seem that in these various forms we have only stages 

 of growth before us. 



Loc. Cretaceous, Meudon ; Tertiary of Australia, Aldinga ; 

 Brendola ; Montecchio Maggiore. 



19. Defrancea brendolensis, sp. nov. (PL III. figs. 2-4.) 

 Zoarium stalked, then spreading out and forming a lamina, which 



has radiate lines underneath. Upper part of the zoarium more or 

 less cup-shaped, with usually 10 to 12 very stout and much raised rays, 

 with the zooecia opening to the outside of the zoarium. Centre of 

 the cup pitted. In one specimen there is no lamina, and in this 

 case there is a regular increase in size from the base, making the 

 zoarium funnel-shaped, and the under surface has large pits, so that 

 it then does not differ from the Cretaceous Bicavea urnula, d'Orb., 

 Pal. Pr. pi. 776, fig. 2. 



D. hrendolensis is allied to the Discotuhigera insignis, Manzoni (Bri. 

 foss. del Mioc. d'Austr. ed Ung. p. 17, pi. xvi. fig. 64); to De- 

 francia (Pelagia) Beyrichii, Reuss (Septar. p. 193) ; to Bicavea, 

 d'Orb., and possibly Discocytis, d'Orb. 



Log. Brendola ; Montecchio Maggiore. 



20. LiCHENOPORA HISPID A (Plomiug). 



TubuUpora stelliformis^ Reuss, Poss, Polyp. Wien. Tert. p. 49, 

 pi. vii. fig. 4. 



Defrancia interrupta^ Reuss, Bry. von Crosaro, p. 258, pi. xxxiv. 

 fig. 12, pi. xxxvi. fig. 9. 



Loc. Living : European Seas ; Australia ; Tristan d'Acunha. 

 Possil: Miocene, Eisenstadt and Morbisch; Pliocene, Crag, Cala- 

 bria. Australia ; New Zealand. Brendola ; Yal di Lonte ; Crosaro ; 

 Montecchio Maggiore. 



21. LlCHENOPOKA (?) Ils'CRTJSTANS, Sp. HOV. (PL III. figS. 8, 9.) 



Zoarium incrusting as a single layer. Zooecia opening vertically 

 with strong bars radiating out to the neighbouring zooecia.
