VERMETUS (PETALOCONCHA) GLOMERATUS. L59 



bleues of Bordighera, 1 together with one from Oakley with which it seems to 

 correspond. 



Imperfect specimens of Vermetus are not very rare at Oakley, but most of them 

 belong to the smaller species, V. glomeratus, next to be described. One of Wood's 

 fossils (pi. xii, fig. 8 b) is probably of that form ; it, is not a typical example of 

 V. iu to rf its. 



The tubes of V. intortus arc squarely angulated and not round. Some speci- 

 mens of Vermetus which I found at Antwerp seem to belong to this species, as do 

 those figured by Nyst (op. cit.) under the present name.

Specific Characters. — Shell tubular; the tubes not being angulated but round, 

 and smaller than in V. intortus, disjoined, irregularly ornamented by transverse 

 and longitudinal ridges, sometimes wound upon themselves in the shape of 

 narrow, continuous, subcylindrical and spiral coils, at others forming agglomerated 

 and confused masses, occasionally of considerable size, without any definite shape 

 or arrangement ; mouth circular ; peristome continuous. 



Dimensions. — Diameter of tube, 2 — 3 mm. 



Distribution. — Recent : Mediterranean and Adriatic, littoral zone. 



Fossil : Coralline Crag : Sutton, Ramsholt. Waltonian : Walton- 

 on-Naze, Beaumont, Little Oakley. Newbournian : Sutton, Waldringfield, 

 Bromswell. 



1 I have just heard from my friend Mr. Clarence Bicknell, of Bordighera, that the interesting 

 sections at that place which formerly yielded so many fossils are now covered with buildings, terraces or 

 gardens.
