354 E,ev. Canon Norman — A Month on 



works it is evidently, I find, that species ; the only difference 

 is that in my specimen, as compared with Middendorff^s 

 fig. 9, the raised spiral portions of the shell are wider and 

 the grooved lines narrower. As to the exact locality of my 

 specimen, nothing can be satisfactorily determined. 



The species is not mentioned in the voyage of the ' Sama- 

 rang;' Schanter Island is certainly to the north of Japan, 

 but whether Adams was ever there or not is uncertain ; as 

 surgeon of one of H.M. ships he may have gone there. 



The shell must unquestionably be referred to the genus 

 Ukko, and possibly may be, as Jeffreys considered, an extreme 

 form of U. Turtoni] but its characters are so marked, and I 

 lay chief stress on the spiral grooving of the inside of the lip, 

 that it may well bear a specific name. 



Whorls 9 ; total length 77 millim. ; greatest breadth 

 8o millim. ; length of mouth and canal 35 millim. ; length 

 from commencement of lip to end of spire 46 millim. Com- 

 paring these measurements with Middendorff"'s figure it will 

 be found that the spire in my example is longer in proportion 

 to the mouth than in the type. The whole appearance of 

 form, amount of convexity of whorl, and obliquity of suture, 

 together with surface sculpture, are like those of typical 

 U. Turtonim miniature. The differences are that the nucleus 

 is not so cylindrical, each succeeding whorl being wider tlian 

 the preceding ; the epidermis is thinner and closely adherent 

 to the shell ; the shell is proportionately more solid, the spiral 

 grooves are more deeply impressed, while the most important 

 character is that the mouth within the shell is lirated with 

 spiral grooves and ridges corresponding to the external 

 sculpture — " apertuva intus ad strias externas regulariter et 

 parallele sulcata" {Middendorjf) . The operculum is imperfect, 

 but enough remains to show that it is like that of the type of 

 the genus.

A dwarf and remarkable form of this variety was found. 

 Volutions 6i. Length '61 millim., breadth 19 millim. ; 

 length of mouth and canal 21 millim. Whorls only slightly 

 convex, suture not deeply impressed and only a little oblique, 

 no spiral sculpture to be seen even in the neighbourhood of 

 the columella ; epidermis of a pale greenish-ash hue.
