66 SUPPLEMENT TO THE CRAG MOLLUSCA. 



Length, \ of an inch. 



Locality. Red Crag, Walton-on-the-Naze {A. Belt). 



This specimen was put into my hands as Eulima distorta by Mr. Bell. The aperture 

 appears to me to be too short for the recent species so called, and resembles a young 

 specimen oijjolita. I therefore assign it to the above species with a note of interro- 

 gation . 



The Paris basin shell first called E. distorta is, I think, with D'Orbigny and 

 Weinkauff, distinct from the existing shell of that name, and I have therefore adopted 

 D'Orbigny's name of similis, which has priority to that of J'/iilippii, proposed for it by 

 Weinkauff. The older tertiary fossil differs in size, as also in the proportions of the 

 aperture, to the length of the shell. The flexure in the spire is present in the young of 

 E. polita. 



Eulima subulata, Donovan. Crag Moll., vol. i, p. 97, Tab. XIX, fig. 3. 



Localities. Cor. Crag, Sutton, Ramsholt, and near Orford. 



In ' Brit. Conch./ vol. iv, p. 209, Mr. Jeffreys observes, in reference to the recent 

 subulata, "This is not the Eulima subulata of Searles Wood nor that of Nyst;" and in 

 the list to the Cor. Crag paper of Mr. Prestwich he repeats this, but at the same time 

 gives the shell as a living West European abysmal form. I am, however, still unable to 

 perceive any difference between the Crag shell and the living British shell subulata, and I 

 have therefore retained the Crag shell under the name I originally assigned to it. 



Eulima bilineata ? Alder. 



Eulima bilineata, Aid. Forbes and Han., vol. iii, p. 238, t. xcii, fig. 9 — 10. 



Locality. Cor. Crag, Sutton. Recent, Britain. 



A specimen of Eulima in my collection, ^th of an inch in length, retains the colouring 

 matter on it, but is not otherwise distinguishable from subulata. This colouring matter 

 forms a broad, fulvous spiral band, occupying the centre of the two lower whorls with 

 traces of another narrow band at the upper and lower part of the same whorls. Mr. 

 Alder in his description of this species says (Forbes and Han., vol. iii, p. 138) that "it 

 has two bands placed close together in the centre of the body whorl, with occasionally a 

 faint indication of another on the upper or lower margin." If by the obscuration due to 

 the fossilization of my shell the two bands placed close together in the centre of the body
