SCISSURELLA. 59 



Unfigured species of Scissurella. 

 Anatomus japonicus A. Adams. 



Shell trochiform, spire conical ; whorls 3£, rather convex, finely 

 decussated by elevated longitudinal stria and close spiral stria?, the 

 longitudinal stria? flexuous on the base ; aperture subcircular ; inner 

 lip dilated and reflexed in the middle. 



This is a large and very beautiful species, very like A. crispatus 

 in sculpture. It also resembles A. conicus Orb., but it is more de- 

 depressed, and instead of being simply striate it is finely decussate; 

 the base of the shell, moreover, is anteriorly produced and angulated. 

 This species and 8. carinata are met with in greater abundance than 

 the other members of the group, and both occur in deep water.

Mino-Sima, 63 fms. ; Seto- Uchi ; Gotto ; O-sima. 



Anatomus lamellatus A. Adams. 



Shell globose-conoidal ; spire conical; whorls 3?, a little convex, 

 cancellated with radiating, subdistant lamellae, and elevated trans- 

 verse lines in the interstices ; lamella? flexuous on the base ; aperture 

 subcircular ; inner lip dilated, angular and broadly reflexed in the 

 middle. 



In form this species is most like A. japonicus ; but the upper part 

 of the whorls is adorned with fine curved radiating lamella?, and the 

 inner lip is broadly reflexed, and partly covers the umbilicus. 



(Ad. I. c, p. 347.) 



Mino-Sima, 63 fms. ; Gotto, 71 fms. ; O-sima, 26 fms. 



Anatomus turbinatus A. Adams. Shell turbiniform ; umbili- 

 cus deep, perspective ; spire elevated ; whorls 4?, a little convex, 

 sculptured with longitudinal, close, radiating lamella?, angular in the 

 middle, and little, elevated, transverse lines ; base ornamented with 

 concentric elevated lira?. This species is elevately turbinate, with 

 two conspicuous carinate whorls and a deep perspective umbilicus. 

 The fine lamella? of the upper part of the whorls are bent or 

 angulated in the middle. (Ad., 1. c, p. 347.) 



Mino-Sima, 63 fms. 



Anatomus concinnus A. Adams. Shell ovate, rather depressed ; 

 spire small, scarcely elevated ; narrowly, profoundly umbilicated ; 

 whorls 2i, convex, decussated by elevated radiating and concentric 

 stria? ; aperture oblique, suborbicular. Under the lens this little 

 species seems to be intermediate in character between A. crispatus
