QuENSTEDT — vcnusta of MuNSTER, fig. in Quenstedt's Cephal- 

 apoda T. xxxii, fig. 8. 



The profusion of Belemnitidse at Churchdown is amazing. In 

 certain beds, the remains lie, not only side by side, but crossing 

 and enmeshed. A peculiarity of the Spinatus Zone is the large 

 size attained by Belemnites paxillosus : this has been also noticed 

 in the Spinatus beds on the Continent. Prof. Phillips observes 

 of the family, that "Bel. elongatus, apicicurvatus, paxillosus and 

 cylindricus taken together, compose a natural group of generally 

 cylindrical or cylindroid forms, with dorso-lateral grooves at 

 apex, and striae on ventral and dorsal aspects. They are 

 unknown in Lower Lias, but go through Middle Lias; and 

 are found in Dorsetshire, Gloucestershire, Northamptonshire, 

 Lincolnshire, and Yorkshire." Phillips, Belemnitidse, iii, p. 87. 



The succession of Belemnites observed at Staithes, apud 

 Phillips, would be this : — 



the Ironstones. 



Bel. cylindricus occurs in Shales above Ironstone series. 

 Bel. rudis -\ 



Bel. breviformis J 

 Bel. numismalis „ the Marlstone. 



Bel. poUex „ the Lower Lias immediately 



below the Marlstone. 



In the " Yorkshire Lias " 1876, the authors have entered as 

 many as 40 species of Belemnites in their Table of Lias fossils. 



It may be assumed from previous remarks that Brachiopoda 

 of the Tretenterata division, are scarcely to be expected in the 

 Spinatus sands under certain special conditions. But an 

 exception has just been noted in the Spinatus Zone of Kings 

 Sutton near Banbury, where a new species of Crania, to which 

 the name of Crania Griffini (Davidson), has been assigned, 

 rewarded the search of Mr. Innes Griffin. It will be figured 

 and described in the 2nd. part of the forthcoming supplement to 

 the Brachiopoda, (Davidson) Palseontographical Society, 1877.
