302 Mr. A. Adams on netv Mollusca from Japan. 



Apertura ampla, septo interno piano semilunari ad partem posti- 

 cam instructa ; margine crenulato, antice valde fissurato. 



Tliis genus seems to combine the characters of Cnjpta and 

 Emarfjhmla, and almost deserves to be considered the type of a 

 new family. The internal septum distinguishes it from all the 

 other Fissurellidce. 



Zeidora calceolina, A. Adams. 



Z. testa oblonga, lineis elevatis conceutricis et radiantibus eleganter 

 cancellata ; sulco mediano lateribus elevatis ; apice postice de- 

 flexo ; septo mavgine acuto, integro. 



Hab. Straits of Korea^ 16 miles from Mino-Sima; 63 fathoms. 



Genus Cranopsis, A. Adams. 



Testa ovata, pileiformis, superficie caelata, apice integro, subspirali, 

 postice recurvo. Perforatio elongata, intus concamerata, inter 

 apieem et marginem anticum posita. Apertura ovalis, expansa, 

 margine crenulato. 



This genus has the internal vaulted chamber over the fora- 

 men, as in Cemoria, and the sculptured surface and median 

 position of the jjerforation, as in Rimula. The specimens serving 

 for the description were all adult shells, and are not the young 

 of Glyphis. 



Cranopsis p)elex, A. Adams. 



C. testa pileiformi, liris radiantibus crenulatis interstitiis cancellatis 

 ornata ; fissura intus concamerata, marginibus callosis, extus labiis 

 elevatis longitudinalibus marginatis ; foramine lineis iucrementi 

 transversis apieem versus currentibus ; margine crenulato. 



Hab» Off Mino-Sima, Straits of Korea ; dredged from 63 

 fathoms. 



Genus Kleinella, A. Adams. 



Testa ovata, tenuis, umbilicata, superficie cancellata ; spira producta, 

 apice obtuso. Apertura elongata, antice producta et Integra ; labio 

 tenui, simplici ; labro postice angulato, in medio recto, margine 

 acuto. 



This genus most nearly resembles Actaon, but is without any 

 fold on the columella ; the umbilicus, moreover, is wide and deep, 

 and the surface of the shell is cancellated. The outer lip forms 

 an angle posteriorly with the last whorl, and is straight in the 

 middle. 



Kleinella cancellaris, A. Adams. 



K. testa oblonga, late et profunde umbilicata ; spira elatiuscula, apice 

 obtuso ; pallide fusca ; anfractibus ^\ convexiusculis (ultimo ven-
