BRITISH BELEMNITES. 



Belenmiies pe7iicillatu8 is the name given by Blainville to the specimen figured 

 in his work (pi. iii, fig. 1). The name had been previously employed by Schlotheim 

 ('Petrif./ No. 10), for a Belemnite which Blainville supposes maybe the same as his 

 examples, which were from the Lias of Nancy. ^ Hardly any foreign author now employs 

 this name J but it appears desirable to revive it, on the authority of Sowerby, who 

 believed his fossils from Lyme Regis to be the same species as Blainville's. The 

 specimens from the Belemnite-bed of Golden Cap have been sometimes referred to 

 B. Nodotianus of D'Orbigny ; but that species is represented with a distinct acro-ventral 

 groove, which rarely, if ever, appears in this, and the section given of its phragmocone is 

 very oval, while in this it is almost circular. The two forms are, however, much allied, 

 though not specifically the same. I have seen only one English specimen which appears 

 to agree with B. Nodotianus. 



Locality. Abundant under Golden Cap, Lyme Regis {^Aiming). Shorn Cliff', Lyme 

 Regis {Soioerby). In Lower Lias, with Amm.. Bucldandi, at Paulton, near Bath, and with 

 A. obtimcs at Hatch, near Taunton {Moore). In Lower Lias (middle part) near 

 Cheltenham {Strickland). In Lower Lias, with A. Turneri, near Bristol {Stoddart). In 

 Lower Lias, Antrim {Phillips) ; and Robin Hood's Bay, Yorkshire {P/iillips).

Guard. Short, conical, arched upwards ; apex acute, usually striated on the dorsal 

 and ventral faces ; two obscure lateral facetles extended and widening over the alveolar 

 region. Transverse section nearly circular, with the axis a little excentric, and nearly 

 straight ; the young forms similar to the full grown.

Greatest length observed, 2" 5 inches; greatest diameter, less than 0-7 ; axis of 

 guard, 0*7. 



1 D'Orbigny twice refers to B. penicillatus, once as the equivalent of B. irregularis, Scli., and again 

 as a synomyin of B. compressut.
