VINE : BRITISH PALAEOZOIC CTENOSTOMATOUS POLYZOA. 
I thought at the time that these remarks would fare better if 
placed before the scientific palaeontologist in a tentative, rather than 
in a positive, form, and in tin's spirit they seem to have been 
accepted by the late Mr. George Busk, for I find in his posthumous 
Challenger Report''' the following paragraph :— 
" No fossil forms belonging either to the Ctenostomata or the 
Ectoproctan Polyzoa have hitherto been identified, but Mr. Vine has 
thrown out a hint, in a paper on Ascodictyon (Ann. Mag. Nat. Hist. 
1884), that perhaps Ascodictyon filiforme may be a primitive represen- 
tative of the Stoloniferous Vesicularida3, or possibly of the Ento- 
procta. That this latter older is of great antiquity is also confirmed 
by its embryonic history, for .... M. Barrois after the most 
careful and elaborate comparison of the larvae of various Ectoproctan 
and Entoproctan groups, comes to the conclusion that the larvae of 
Entoprocta represents the primitive type from which all the others 
are derived." Vol. xvii. p. 4. 
Quite recently Mr. E. 0. Ulrich, of America, in a paper on New 
Lower Silurian Bryozoa from the Trenton Shales of Minnesota, + pro- 
posed a new genus, Vinella, for the reception of some peculiar 
organisms found both in America and in England. The genus 
Vinella, Mr. Ulrich' s remarks, is proposed " for an adnate form sup- 
posed to be a Ctenostomatous Bryozoon, with relation to Vesicularia, 
Thompson, and probably also to Mimosella Hincks. ... As 
interpreted by me the fossils for whose reception this genus is pro- 
posed represents the stoloniferous part of the bryozoon only. The 
Zceocia I regard as having been deciduous and developed by budding 
from the creeping stolons at the parts now represented by small 
pores." In naming the genus in my " honor' - Mr. Ulrich says that 
I " was the first to suggest the relation of Rhopalonaria and Asco- 
dictyon to the Ctenostomatous Bryozoa." 
My last reference is to Mr. Ulrich' s synopsis of classification 
which prefaces his descriptions of the Palaeozoic Bryozoa, in vol. viii. 
of the Palaeontology of Illinois % It is rather strange that indepen-
