Victorian Fossils, Part XXII. ;32:3 



Prof. Blake has suggested (loc. cit. p. 240), " may very well l;e the 

 j-eiiiains of the intestine filled with matrix." This fossil form is 

 now before, me, two fine examples having been given to me on my 

 departure for Australia in 1902, by Mr. Howard Fox, F.G.S., wlio 

 discovered them, and who then wrote (Dec. 22nd, 1901) : *' I enclose 

 a specimen of a fossil I have found abundantly at Bedruthan Steps, 

 ^'orth Cornwall, and of which Upfield Green the year previous 

 found two specimens on the south coast. Fteroconus mirus, Hinde 

 (syn, yereifojjsis. Green). If you hnd any like it at Melbourne 

 5end me word. It seems to be a new form. Whidborne calls it 

 <Cor//ulites." 



My object in writing this note is to draw attention to the corro- 

 borative evidence afforded by this related genus that Corniilifes and 

 Pteroconus (or yereifopsis) are tubicolous annelids.^ In my speci- 

 men of Pferocpnits the basal extremity in each case is expanded, 

 .and shows signs of attachment in the larger specimen. Fteroconvs 

 lias not yet been found in the Australian paleozoic sediments.
