408 MR. G. C. CRICK ON CARBONIFEROUS CEPHALOPODA [Allg. 1 9. 1 I, 



states (op. cit. p. 35), 



' a common fossil in the upper beds of the Lower Culm {Posidonomya Beds) . . . 

 both in the northern and southern outcrops.' 



Dr. Hind & Mr. Howe record the species from the Pendleside 

 Group at Pendle Hill l ; it has also been recorded from Congleton 

 Edge (Cheshire), 2 and from South Wales. 3

This species appears to be represented by an impression on the 

 surface of a small slab, labelled ' Waddon Barton,' which does 

 not exhibit any example of Glyphioceras spirale, the form most 

 commonly occurring at this locality. Phillips's type-specimen came 

 from Black Hall, Bolland, 6 and he recorded the species also from 

 Westleigh in North Devon. 7 Dr. Hind & Mr. Howe record the 

 species from the Pendleside Group at Black Hall, Bolland, and 

 from near Todmorden ; also from the Venn and Swimbridge Culm 

 Shales of North Devon. 8 It has been recorded from Codden Hill, 

 near Barnstaple, 9 and doubtfully from Waddon Barton, 10 near Chud- 

 leigh (South Devon).

Prolecanites (?) sp. 



The British Museum collection contains from Pinhoe the impres- 

 sion (in part of a nodule) of one side of a slowly-increasing shell, 

 elliptical in outline, its diameters being about 45 and 30 mm. 

 respectively, the corresponding measurements of the umbilicus being 

 25 and 15 mm. respectively. The whorls seem to have been 

 rather compressed, the margin of the periphery subangular, the 

 umbilicus wide and its walls step-shaped, the umbilical zone of the 

 whorl fairly well defined, relatively narrow and convex. The test 

 appears to have been ornamented with extremely faint striae ; these
