AMAUEOPSIS JAPONICA. 703 



Amauropsis japonica, A. Adams, MS. Plate LVI, fig. 27. 



1879. Natica (Amauropsis) japonica, S. V. Wood, Mori. Crag Moll., 2nd Suppl., p. 30, pi. iii, p. 11. 



Specific Characters. — Shell small, thin, fragile, ovato-conical ; whorls convex, 

 turreted, the last much the largest, three-fourths the total length ; suture deep, 

 depressed ; spire short, rapidly diminishing to a blunt point ; mouth ovate ; outer 

 lip thin, gently rounded ; inner lip spread over the columella, which is oblique 

 above and straight below. 



Dimensions. — L. 8 mm. B. 4 mm. 



Distribution. — Recent : Japan. 



Fossil : Butleyan Crag : Butley, Hollesley. 



Remarks. — The shell here figured was found by Mr. Kennard at Hollesley. 

 It resembles the Butley specimen described by Wood except that the spire is 

 shorter and that the umbilicus is covered by the inner lip. The latter was 

 identified by Wood rather doubtfully with a recent species from Japan which he 

 had not seen. I am unable to throw any further light on the subject.

1901. Amaura Candida, Kobelt, Icon, sclialentrag. europ. Meeresconch., vol. ii, p. 110, pi. lvii, fig. 15. 



Specific Characters. — Shell small, ovato-oblong, imperforate; whorls 5, the last 

 much the largest ; spire produced, exserted, with a rather obtuse apex ; mouth 

 pyriform, acutely angulate above, obtusely rounded below ; columella short. 



Dimensions. — L. 12 mm. B. 5 mm. 



Distribution. — Recent ; Greenland. 



Fossil : Waltonian Crag : Little Oakley. Butleyan : Butley. 



Remarks. — This species was originally identified by Mr. A. Bell from a specimen 

 found by him at Butley ; another was afterwards obtained from the same locality 

 by the late Mr. Crowfoot which is now figured. It seems to be a rare and distinctly 

 arctic form.
