408 Mr. A. Adams on new Mollusca from Japan. 



intrinsecus decurrente, ct in dentem acuium desinente ; labro acuto 



intus leevi. 



This little genus most nearly approaches Elcnchus, but the 

 form is different : the outer lip is not lirate or grooved within ; 

 and there is a peculiar defined callus (ending in a very conspi- 

 cuous tooth), extending the greater part of the length of the inner 

 lip. Only a single specimen of each species was obtained. 



Alcyna ocellata, A. Adams. 



A. testa Isevi, imperforata ; anfractibus convexiusculis, pallide carneo- 

 rufescentibus, anfractu ultimo cingula macularum ocellatarum 

 (pupillis rufescentibus, viridibus, albidis) ornato ; callo parietali in 

 dentem validum prominentem acutum desiuente. 



Hab. Sea of Japan ; off Talen-Sima ; dredged from 25 fathoms. 



Alcyna lepida } A. Adams. 



A. testa Isevi nitida imperforata, pallide rufo-fusca, lineolis nigrican- 

 tibus transversis circumcincta, apice nigricante ; anfractibus 5, 

 plauiusculis ; callo parietali in dentem parvum acntum desinente. 



Hab. Sea of Japan ; off Talen-Sima ; dredged from 25 fathoms. 



Genus ENIDA, A. Adams. 



Testa depresso-conica, late umbilicata; anfractibus convexiusculis, 



cingulis concentricis granulosis aut squamulosis ornatis, suturis 



canaliculatis, anfractu ultimo ad peripheriam carinato vel angu- 



lato. Apertura subquadrata ; labio in medio reflexo ; labro intus 



simplici aut lirato ; umbilico amplo, margine crenulato. 



I have dedicated this germs to the gentle Lady Enid of the 



Poet-Laureate's ' Idylls of the King/ a creation of the brain 



more beautiful, more tender, and more pure, than any of the 



so-called goddesses of the Greek mythology who have lent their 



names to science. Enida, founded on shells of great beauty and 



of exquisite sculpture, resembles a depressed and widely umbili- 



cated Zizyphinus with the inner lip reflexed; in form it also 



approaches many species of Gibbula, but this group is littoral and 



coarser in its physiognomy. Deep-water shells are usually more 



delicate and of finer sculpture than those which have to buffet 



with the tides. 



Enida Japonica, A. Adams. 



E. testa depresso-conica, profunde umbilicata ; anfractibus 5, con- 

 vexiusculis, liris transversis granulosis (interstitiis oblique longitu- 

 dinaliter striatis) ornatis, anfractu ultimo ad peripheriam carina 

 crenulata prominente cincto ; apertura subquadrata, labio in 

 medio reflexo, labro intus Isevi, basi liris concentricis granulosis 

 confertis instructa ; urnbilico mediocri. Colore pallide fusco, ma- 

 culis radiantibus fuscis ornato. 



Hab. OffMino-Sirna; 63 fathoms. 



This appears to be the most abundant species but all the
