SCISSURELLA. 59 



Unfigured species of Scissurella. 

 ANATOMUS JAPONICUS A. Adams. 



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

 decussated by elevated longitudinal striae and close spiral striae, the 

 longitudinal striae flexuous on the base ; aperture subcircular ; inner 

 lip dilated and retiexed 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 S. 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 ; 0-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 ; lamellae 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 lamellae, and the 

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



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



Mino-Sima, 63 fms. ; Gotto, 71 fins. ; 0-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 lamellae, angular in the 

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

 concentric elevated lirae. This species is elevately turbinate, with 

 two conspicuous carinate whorls and a deep perspective umbilicus. 

 The fine lamellae of the upper part of the whorls are bent or 

 angulated in the middle. j(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 2 2, convex, decussated by elevated radiating and concentric 

 striae; aperture oblique, suborbicular. Under the lens this little 

 species seems to be intermediate in character between A. crispatus
