574 PLIOCENE MOLLUSCA. 



Bemarlcs. — The specimen from which this shell takes its name was obtained by 

 Mr. Jas. ReeA^e at Bramerton more than forty years ago and sent to Wood for 

 description. Strictly speaking, the name should be attributed to the former 

 investigator, as it was first published by him in 1878, a year before the 2nd 

 Supplement to Wood's Monograph of the Crag Mollusca. Mr. Reeve's work on the 

 Bramerton Crag was so painstaking and long-continued that it Avill give everyone 

 who knew of it pleasure to find that this well-deserved though long-overlooked 

 compliment should lie paid him. 



Var. acuminata, nov. Plate XLIX, fig. 30. 



Varietal Charaders. — Differs from the type form in size and in its more slender 

 and acuminate spire. 



Dimensions. — L. 7 mm. B. 1 ■75 mm. 



DiiifriJ>ntioii. — Not known living. 



Fossil : Little Oakley. 



Bemirl-s. — This shell differs sufficiently, I think, from the form generally found 

 in the Crag to deserve a distiuct varietal name. 



Var. conica, nov. Plate XLIX, figs. 37, 38. 



1871. OiJodoiuia {Cheiini.) internodula, A. Bell, Aim. Mag. Nat. Hist. [4], vol. vii, p. 359. 



Varietal Characters. — Differs from the type in its conical spire, which is shorter^ 

 and less slender and elongate than in the type. 



Dimensions. — L. 5 — 7 mm. B. 2 — 2'5 mm. 



Distribution. — Not known living. 



Fosf'il : Waltonian Crag : Walton-on-Naze. Icenian : Bramerton. 



Remarlcs. — The distribution of this variety has not been worked out, but it 

 might be found, not improbably, at most localities from Boyton to Bramerton where 

 the type form is present. The only reference to it I can find is that of Mr. Bell, 

 who, in the paper given above, speaks of a short conical variety of Odostomia inter- 

 nodula up to that time unnoticed by Wood, which he remarked was not uncommon 

 in both the Coralline and Red Crags.
