NOETH-ITALIAN BBYOZOA. 7 



A specimen from Montecchio Maggiore seems to be of this species. 

 It is without avicularia on either surface ; but at the outer angle of 

 each zooecium there has been a vibraculum (or strong spine), and 

 the vibracular chamber is tubular. There has been a scutum over 

 the front. I do not find in any of my specimens of Scrupocellaria 

 from ISTorth Italy that there has been an avicularium at the outer 

 angle. Eeuss seems to have taken the vibraculum for an avicu- 

 larium.

6. SCEFPOCELLAEIA BEElSTDOLElSrSIS, Sp. nOV. (PL I. figS. 14, 15.) 



The opesial aperture is about one half of the length of the zooe- 

 cium ; near the middle on the inner side the aperture is contracted, 

 no doubt by the base of the scutum ; below the aperture there is a 

 triangular avicularium directed outwards ; at the upper outer angle 

 there has been a vibracular appendage or a spine. On the dorsal 

 surface there is a vibraculum to each zooecium, with the base 

 attached in a small semicircular chamber near the inner edge of the 

 zooecium. 



This would seem related to S. scabra, but differs from it in not 

 having any avicularium at the outer upper angle. 



Log. San Clementa (Montecchio Maggiore) ; Brendola. 



7. SCETJPOCELLAEIA MOIJfTECCHIEirSlS, Sp. UOV. (PL I. figS. 21, 22.) 



The specimen figured cannot be identified with any of the others, 

 and it therefore seems advisable to give it a name, though at best 

 the determination of fragments of Scrwpocellarice is not very satis- 

 factory. 



The aperture is very large; there has been no scutum ; and the 

 vibracular chamber on the dorsal surface is ver}^ large, so that the 

 external prolongation is also seen from the front. 



Log. Montecchio Maggiore.

 pi. V. fig. 28 ; Bryoz. von Crosaro, p. 2QQ^ pi. xxxi. figs. 5, 6. 



The aperture is Schizoporellidan, with a wide sinus. The groove 

 on the dorsal surface is usually very wide and deep, as figured by 

 E-euss, but at other times there is not more than a divisional line. 



In the mode of growth this seems nearly related to Urceolipora 

 and to Iclithyaria oculata, B.
