but unfortunately the suture-lines are not visible in the specimens 

 from Devon. An examination of a number of examples of the 

 two species leads me to endorse Phillips's statement that the two 

 species are closely allied, if not the same. 



With this species is identified a well-preserved example, 19 mm. 

 in diameter, in the Exeter Museum, labelled ' Dunsford Eoad. 

 above Pocombe Bridge.' 



Imperfect impressions of shells and quite young specimens from 

 the 'bottom of Ashlake Eoad ' and a young shell from Willh ayes 

 Copse probably belong to this species, which we have also recognized 

 from ' Mincing Lake.'" 



The British Museum collection includes from the Yicary Bequest 

 two examples from Xewton St. Gyres, 4 miles north of Exeter, that 

 belong to this species. They are 18*5 and 13*5 mm. in diameter 

 respectively, the smaller one having a still smaller example (4 mm. 

 in diameter) attached to it. 



To this species is also referred an example from ' under Stoke 

 Wood,' measuring rather more than 20 mm. in diameter, exhibiting 

 the sculpture of the test. Embedded in the same piece of matrix is 

 a specimen apparently referable to Glyphioceras inconstans. 



Dr. Hind records the species from Doddiscombleigh (South 

 Devon), 1 and states that 



' this species occurs at certain horizons in the Pendleside Series, in practically 

 every locality in the Midlands where these beds occur.' 



He also records it from the marine band beneath the Gin-Mine 

 Coal at Nettlebank (North Staffordshire). 2 It has moreover been 

 recorded from the- Lower Coal-Measures of Lancashire 3 and from 

 South Wales. 4

This species is represented from Mincing Lake by a portion of 

 the outer whorl, with the included part of the penultimate whorl of 

 a rather large example. The inner whorls are wanting. 



The portion of the penultimate whorl consists of about a third 

 of a volution, is sublanceolate in cross-section, being at its mid- 

 length about 24 mm. high and 21 mm. thick at its prominent 

 rounded umbilical margin. The outer third of the whorl is pinched
