LOWER-DEVONIAN SPECIES. 



All the fossils occur as either internal casts or impressions of the exterior ; and are 

 found in light-yellow, or reddish, or grey sandstones and quartzites, the rock agreeing 

 entirely in aspect and composition with that of some sandstones and quartzites that 

 occur in situ in Normandy and Brittany on the other side of the Channel. 



This Devonian sandstone agrees also with the Lower-Devonian Sandstone or " Gres 

 Devonien inferieur a Orthis Motinieri,'' of French geologists, which may be seen at 

 Gahard and other places. 



1. Terebratula sacculus, Martin. Dav., Dev. Mon., PI. I, figs. 1 — 8; Budl.-Salt. 



Sup., PI. XXXVIII, figs. 1, 2, 3. 



Among some specimens from Budleigh-Salterton, lent to me by Mr. W. Vicary and 

 Mr. W. Linford, I at once recognised two small internal casts, and one impression of an 

 exterior of Martin's species. 



Internal casts of the following three species are provisionally classed in the genus 

 Alhgris ; but from these one or two will probably have to be removed when more 

 satisfactory and complete material shall have been obtained.
