342 THE FORAMINIFERA OF THE EXE ESTUARY. 



LIST OF SPECIES TAKEN. 



[Xomcnclature : Brady, Clialknger Report, i\.'\ 



BiLOCULiNA RiNGENS {Lamarck). One individual somewhat doubt- 

 fully identified, from Salthouse Lake. 



MiLiOLiNA SEMINULUM (lAun.). Dead shells from the southern slope 

 of the Polesands. One of the four or five commoner species from 

 the Warren, Salthouse Lake, and Lympstone ; and decidedly one of the 

 more prominent on the bed of Exmouth Docks. Nowhere really 

 plentiful, and no large, well-grown specimens obtained except from 

 the south slope of the Polesands. 



Haplophragmium canaeiense {(VOrhigny). A single individual from 

 Salthouse Lake. 



Trochammina inflata {Montagu). At low-water mark on Warren 

 and from Salthouse Lake. Well-grown specimens. 



Verneuilina polystropha {Beiiss). Pound at Lympstone and in 

 Exmouth Docks. Appears in this estuary to replace the Textidaria, 

 no specimen of either Textularia gramen, aggluthuais, or saggitula 

 having been found. 



BuLiMiNA PUPOIDES, d'Orhiguy. Single individuals from Warren and 

 Salthouse Lake ; five times as plentiful in Exmouth Docks, which is not 

 a typical ground for this species. Probably, however, Bulimina, in 

 common with all the more elongate Foraminifera, suffers more than 

 the lenticular forms from the tidal scour. The actual number present 

 in the sample from the docks does not compare with the representation 

 of this species on grounds where it is really at home. 



BoLiviNA dilatata, Rcuss. Found at Warren, Salthouse Lake, and 

 Exmouth Docks ; in neither case more than barely represented. From 

 some results not numerically stated above, is probably more plentiful 

 in the docks than elsewhere. 



Bolivina textilaroides, Eeuss. Exmouth Docks. 



Lagena hexagona {Williamson). Salthouse Lake only, but may 

 occur elsewhere; distinctly rare however. 



Lagena orbignyana {Seguenza). Six floated from G-5 gms., Warren ; 

 one from 6-5 gms., Salthouse Lake ; eighteen from similar quantity, 

 Lympstone ; and eleven from Exmouth Docks. A light shell of small 

 size which succeeds here in establishing itself in comparatively quiet 

 situations. Compared with its occasional numbers, it is poorly repre- 

 sented at all the stations mentioned above. 



PoLYMORPHiNA COMPRESSA, (VOrhigny. Infrequent. 



Spirii-lina. One of doubtful species, from Warren.
