346 Mr. A. Adams on new Species of Scissurellidse 



animal of Limopsis are confessedly meagre, I have been induced 

 to publish them in consequence of nothing being yet known on 

 the subject ; and at any rate I hope this notice of another link 

 being supplied in the chain which connects the tertiary with the 

 recent fauna may not be uninteresting to naturalists. 



XXXVIII. — On some new Species of Scissurellidse from the Seas 

 of China and Japan. By Arthur Adams, F.L.S. &c. 



The genus Scissurella of D'Orbigny is distinguished from Ana- 

 tomus, H. & A. Adams, in being provided with a foramen instead 

 of a fissure. It is synonymous with Schismope of Jeffreys, and 

 Woodwardia of Crosse and Fischer. The new species of Scissu- 

 rella and Anatomus which I now describe, from the seas of China 

 and Japan, were dredged from deep water and from a bottom of 

 sandy mud and broken shells. 



1. Scissurella carinata, A. Adams. 



S. testa ovata, depressa ; spira planiuscula ; anfractibus 2|, planis, 

 ultimo supra carinam striis radiantibus (ad suturas validioribus) 

 instructo, infra carinam cingulis elevatis transversis ornato, basi 

 lineis elevatis concentricis, interstitiis cancellatis instructo ; aper- 

 tura obliqua ; labio recedente. 



Hab. Okosiri ; 35 fathoms. Seto-Uchi; 16 fathoms. Gotto ; 

 71 fathoms. 



This species and the others I have named Scissurella have a 

 foramen instead of a fissure, and would be called by some Schis- 

 mope or Woodwardia, both of which names I believe to be syno- 

 nyms of Scissurella proper. S. carinata has a flattened spire 

 and three prominent keels on the last whorl below the carinate 

 periphery. It most nearly resembles S. d'Orbignyi; but there 

 are three keels besides the fissural carina. 



2. Scissurella modesta, A. Adams. 



S. testa ovata, depressa, stomatelliformi, anguste umbilicata ; spira 

 parva vix elata ; aufractu ultimo supra carinam concentrice striato, 

 infra carinam longitudinaliter plicato, basi lirulis spiralibus or- 

 nato ; apertura perobliqua, transversim ovata. 



Hab. Tabu-Sima; 25 fathoms. 



A small simple white species, without keels, striated above the 

 somewhat rounded periphery, and obsoletely plicate below. 



3. Scissurella miranda, A. Adams. 



S. testa ovata, depressa, late umbilicata ; spira planiuscula ; anfractu 



ultimo supra carinam subtilissime concentrice striato, infra cari- 



l nam plicis obliquis subnodosis longitudinalibus distantibus ornato,
