Specific Characters. — Shell slender, thinner, smaller and more delicate than 

 E. terebellata, with a rounded or only slightly angulatod l)aso; whoi'ls 8 or 9, 

 smooth and somewhat convex ; spire elongate, regularly tapering to an acute 

 point; suture slight; mouth ovate, compressed above, projecting below ; periphery 

 continuous ; inner lip narrow, nearly covering a small umbilicus. 



D 17)1671 sions. — L. 14 mm. B. G mm. 



Distrlhiifiou. — Not known living. 



Fossil : Waltonian Crag : AValton-on-Naze, Beaumont, Tjittle 

 Oakley. Newbournian : Beiitley, Waldringfield, Sutton, Newbourn, Felixstowe. 

 Butleyan : Bawdsey, Alderton, Butley. 



Beiuarl's. — As stated above this is generally a more slender and delicate shell 

 than E. ferehellata. Like that species it seems to be almost entirely confined to 

 the Red Crag and, rather doubtfully, to beds of similar age in Belgium and 

 Holland, occurring, however, as does the former, though not abundantly, at 

 St. Erth. Dr. Tesch reports it from one of the Dutch borings at Oploo as E. 

 pendula, but a specimen he has kindly sent me (fig. 24) seems nearly allied to 

 E. terebellata, and may be an intermediate form. 



Var. parva, nov. Plate L, fig. 28. 



Dimensloiis. — L. 9 mm. B. 4 mm. 



Distribution . — Not knoAvn living. 



Fossil : Waltonian Crag : Little Oakley ; probably elsewhere in 

 the Red Crag. 



Remaiks. — The specimen figured under this name is not uncommon in the 

 Waltonian of Oakley. It appears to be full grown and may be regarded as a 

 dwarf variety of the typical E. 'pendula. Its distribution has not been worked out 

 at present.

1893—98. Eulimene pendula, var. turgida, A. Bell, Proc. Roy. Irish Acad. [3], vol. ii, p. 629, 1893; 

 Trans. Eoy. Geol. Soc. Cornwall, vol. xii, p. 150, 1898. 



Specific Characters. — Shorter and wider than the type form of E. pendula ; 

 whorls slightly convex, the last tumid, rounded at the base ; spire abruptly 

 tapering to a very small and pointed apex ; suture deeper.
