vine: polyzoa of the wenlock shales. 
189 
aware of the wonderful richness of forms brought to light by Ubich 
and others, I should not have ventured upon the placement therein 
suggested. In a recent paper on the Genus Fistulipora M'Coy (amend 
Nicholson and Foord,t) the authors, besides giving a new nomen- 
clature for certain structural features, place the Carboniferous species 
referred to above, as a synon}Tn of Fistulipora incrustans, (=Calam- 
pora id. PhiUip's Geology of Yorkshire). I am obliged to accept the 
placement of the authors because they were able to examine the 
original specimen of Phillips, " now preserved in the British 
Museum." (1. c, p. 501.) 
Family II. — Tubuliporida. 
British Association Rep. Fobs. Polyzoa, 1883. 
Zoarium adherent, more or less free, flabellate, lobate, or cylin- 
drical. Zosecia tubular, disposed in contiguous series. Ooecium, an 
inflation of the surface of the zoarium at certain points, or a modi- 
fled cell. 
Genus DiASTOPORA ? Lamx. 
„ Diastoporella, Vine. 
Entalophora, Lamouroux. 
It must be apparent to the student that the generic grouping of 
this family is undoubtedly artificial, yet under present circumstances 
it is impossible that it should be otherwise. The Diastopora of the 
palaeozoic rocks are entirely unlike the Diastopora of the latter rocks, 
and it is very questionable whether a real afiinity could be consistently 
established, yet it would be folly to seperate them, unless we entirely 
restrict the genus Berenicea" for palaeozoic species alone. In his 
elaborate papers on American palaeozoic Bryozoa, Mr. E. 0. Ulrich 
describes two species as Berenicea: — B. primitiva Ul., and B. vesi- 
culosa Ul. : but I cannot see from his description of either genus or 
species that he seeks to separate them from the mesozoic or recent 
forms — in other words, his idea of Berenicea is the same as that of 
t Ann. Blag. Nat. Hist. Dec. 1885, pp. 496-51 7.
