66 SUPPLEMENT TO THE CRAG MOLLUSCA. 
Length, + of an inch. 
Locality. Red Crag, Walton-on-the-Naze (4. Bell). 
This specimen was put into my hands as Hulima distorta by Mr. Bell. The aperture 
appears to me to be too short for the recent species so called, and resembles a young 
specimen of polita. I therefore assign it to the above species with a note of interro- 
gation. 
The Paris basin shell first called &. 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 szmz/is, which has priority to that of Pdclippii, proposed for it by 
Weinkauff. The older tertiary fossil differs im 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 
Lf. polita.

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 Hulima 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 livmg British shell swdulata, and I 
have therefore retamed the Crag shell under the name I originally assigned to it.

Locality. Cor. Crag, Sutton. Recent, Britain. 
A specimen of Hwlima in my collection, th of an inch in length, retains the colouring 
matter on it, but is not otherwise distinguishable from swéulata. 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. ii, 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
