162 MK, A. W. WATERS ON NOETH ITALIAN BETOZOA. 



Until this was properly cleaned it looked like Diastojpora. There 

 are no signs of a radial or discoid growth and the structure reminds 

 us of that oiHeteropora, so that it is difficult to know where it should 

 be generically placed. 



I have not had suitable material for making sections in order to 

 study whether the cross-bars are hoUoAV. 



Log, Brendola and Montecchio Maggiore. 



22. Heteeopoea subretictjlata (Eeuss). 



Heteropora suhi^eticidata, Reuss, Bry. von Crosaro, p. 288, pi. xxxvi. 

 fig. 7 ; Pergens, Bry. von Wola Lu'zanska, p. Qb. 



Heteropora reticulata^ Marsson {non Busk), Bry. Rugen. Kreide, 

 p. 2Q, pi. ii. fig. 4. 



A specimen from Brendola twice dichotomizes. Zoarium about 

 1 millim. wide. This, I believe, is the same as a specimen I have 

 seen from the Chalk of Gravesend and which was then considered to 

 be Clausa micropora. As already remarked by Reuss, the zooecia are' 

 more abundant upon the one side than upon the opposite. The can- 

 celli are situated in deep pits, and in well-preserved specimens are 

 much smaller than the oral apertures. Oral aperture about 0*07 

 mm. wide. 



Loc. Yai di Lonte (i^ewss) ; Brendola; Halo; Wola Lu'zanska. 

 Cretaceous, Eiigen. 



Note. — To the Chilostoniatous species mentioned in my previous 

 paper I would add Microporella distoma, Busk, from Malo, I^ovezzina, 

 and Crosaro.

Discussion. 



Dr. G. J. HiNDE said that the revision of the characters and 

 classification of the Bryozoa, so carefully carried out by Mr. Waters, 

 was of considerable importance to all students of these forms.
