the periphery ; it exhibits a single faint constriction, but no suture- 

 lines, and therefore apparently formed part of the body-chamber. 

 It is doubtfully referred to this species. 



Prom Bonhay Road, Exeter, and forming part of the Yicary 

 Bequest, the British Museum collection includes a somewhat dis- 

 torted pyritized internal cast, 28 mm. in diameter, 17*5 mm. thick, 

 •with an umbilicus 3*5 mm. wide, having the septal sutures and 

 shell-ornament characteristic of this species. 



The locality of the type-specimen is ' Bolland/ the other localities 

 for the species given by its author being Queen's County, Ferma- 

 nagh, and the Isle of Man. Phillips 1 subsequently recorded the 

 species from Swimbridge and Yenn in North Devon, and from 

 Trescot in South Devon. Dr. Wheelton Hind also records it from 

 the black shales and limestones at Yenn. 2 



Mr. Ussher 3 records the occurrence of this species in a 'dark- 

 grey hard mudstone' at Perridge Tunnel, but the only example 

 submitted to the writer from this locality does not exhibit the 

 characteristic sculpture of the species. It is here referred to 

 Glyphioceras striolatum. 



Dr. W. Hind & Mr. J. A. Howe record this species from the 

 Carboniferous Limestone of Yorkshire and Derbyshire i ; while 

 from the Poolvash Limestone (Isle of Man) the species has been 

 recorded both by the same authors and by Mr. G. W. Lamplugh. 5

This species is well represented from Waddon Barton, in the 

 collections both of Mr. Collins and of the British Museum, by the 

 ordinary crushed examples exhibiting the strong longitudinal orna- 

 ments and the periodical constrictions. Mr. Collins's collection also 

 includes a beautifully-preserved example from Popehouse Close, 

 Christow. 



Besides Waddon Barton in South Devon, the species occurs at 

 Bampton, 7 Hele 8 and Yenn 9 in North Devon, being, as Mr. Ussher
