W. J. SoUas — The Genus Wehhina. 



The German Government geologists consider the Biidesheim beds 

 as Upper Devonian. If they are right, is it not probable that we 

 should be correct in dropping the term " Upper South Devon," and 

 simply calling these beds " Upper Devonian" ? 



It may be well to add that the same beds a little to the northward, 

 at the extreme south end of Goodrington Sands, have yielded several 

 specimens of Pleurodvctyum prohlematicum and sections of large 

 Crinoidal stems. There are also many indefinite markings in the 

 red sandy shale bearing a great resemblance to vegetable remains.

III. — On the Perforate Character or the Genus Webbina, with a 

 Notice of Two New Species, W. l^vis and W. tuberoulata, 

 FROM the Cambridge Greensand. 



By W. J. SoLLAs, B.A., F.G.S. 

 (PLATE VI.) 



THE well-known genus TrocTiammina was instituted in 1859 ^ by 

 Messrs. Parker and Jones as a sub-genus for the reception of 

 an arenaceous foramiaifer, the Botalia (Nautilus) inflata of Muntagu. 



Subsequent researches led these obsei-vers in the following year ^ 

 to elevate it to the rank of a distinct genus, and it was at the same 

 time made to embrace the important series of forms then known as 

 Wehhina irregularis, D'Orb. 



In the incomplete list of the genera of Foraminifera occurring in 

 the Cambridge Greensand, furnished by me to the Journal of the 

 Geological Society ^ some time ago, Trochammina is enumerated as a 

 somewhat abundant form, on the evidence of numerous examples of 

 what I regarded at the time as specimens of Wehhina irregularis, and 

 which indeed so closely resemble this species in external form and 

 appearance, as to have led Mr. Brady to form the same opinion iu 

 regard to them as myself. 



It did not occur to me to question the arenaceous character of these 

 forms, till, in examining a thin slice of Ventriculite, preserved, like 

 most of the fossils of the Cambridge Greensand bed, in calcic phos- 

 phate, I observed two specimens of a foraminifer in section presenting 

 the same outline as that of the supposed W. irregularis, and adherent,
