1887. Liocekas bradfoudense, This Monogr., PI. v ; PI. iv, fig. 8 only. 



Description. — Platyleptogyral, excentri-gradumbilicate, parvi-subobsoleticos- 

 tate. 



Distinction. — From patellaria, less costation.

 bed ; Stoke Knap, from the Building Stone ; Cbideock, from base of Building 

 Stone. 



Date of Existence. — Bradfordensis hemera. 



3. Ai'EDOGYRiA ? subcoenuta, S. Buckman. Suppl., Plate XIV, figs. 13 — 15. 



Description. — Platyleptogyral, excentri-gradumbilicate, subdensiseptate, brevi- 

 angustilobate, densi-parvi-costate. 



Notes. — The periphery is very narrow and subfastigate. Accompanying the 

 excentrumbilicatum there is a slight increase in progressive thickness of whorl. 

 The mouth-border has short (incomplete) lateral lappets ; hence the specific name. 



Remarks. — The generic position is not quite satisfactory, though there is fair 

 agreement in radial and suture-lines. 



Distinction. — From platychora, costas smaller and more numerous, different 

 umbilication. 



There is a similarity to Am. Murchisonss intralsevis. Quenstedt, 2 except in the 

 costation, which, in this fossil, is more angulate. 



Localities and Strata. — Dorset : Horn Park, near Beaminster, in the lower, 

 not ironshot, beds, about the horizon of Zeilleria anglica (Oppel) ; Chideock, 

 top of " Wild Bed " or base of Building Stone ; Somerset : Stoford, from a grey 

 limestone. 



Date of Existence. — Murcliisonae hemera.
