from the Seas of China and Japan. 347 



basi lineis conccntricis instructo ; apertura perobliqua, transversim 

 ovata. 



Hab. Mino-Sima; 63 fathoms. 



In this small but very pretty species the last whorl is nodosely 

 plicate below the fissural keel. 



Genus Anatomus, H. & A. Adams. 



By common consent, the somewhat mythical Anatomus of 

 Denys de Montfort has been ignored. His name Anatomus, 

 however, a very significant and good one, may still be used for 

 those species of Scissurella in which the margin of the outer lip 

 is fissured. Woodward has unnecessarily suggested the altera- 

 tion Anatoma, for the sake, possibly, of the feminine termination. 



1. Anatomus japonicus, A.Adams. 



A. testa trochiformi ; spira conica; anfractibus 3|, convexiusculis, 

 striis elevatis longitudinalibus et transversis confertis concinne 

 decussatis, striis longitudinalibus in basi flexuosis ; apertura sub- 

 circulari ; labio in medio dilatato et reflexo. 



Hab. Mino-Sima; 63 fathoms. Seto-Uchi. Gotto. O-Sima. 



This is a large and extremely beautiful species, very like^4.cm- 

 patus in sculpture. It also resembles A. conicus, D'Orbigny, 

 but it is more 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 Scissurella carinata 

 are met with in greater abundance than the other members of 

 the group, and both occur in deep water. 



2. Anatomus lamellatus, A. Adams. 



A. testa globoso-conoidea; spira conica; anfractibus 34, convexiusculis, 

 lamellis radiantibus, subdistantibus, interstitiis lineis elevatis trans- 

 versis concinne cancellatis, lamellis in basi flexuosis ; apertura sub- 

 circulari ; labio in medio dilatato, angulato, et late reflexo. 



Hab. Mino-Sima; 63 fathoms. Gotto; 71 fathoms. O-Sima; 

 26 fathoms- 



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. 



3. Anatomus turbinatus, A. Adams. 



A. testa turbiniformi ; umbilico profuudo, perspectivo ; spira elata ; 

 anfractibus 4|, convexiusculis, lamellis confertis radiantibus (in 

 medio angulatis) et lineolis elevatis transversis instructis, basi liris 

 concentricis elevatis ornato. 



Hab. Mino-Sima; 63 fathoms.
