intrlnseciis decurrcnte, et in dentem acutum desineute ; labro acuto 



intus Isevi. 



This little genus most nearly approaches Elenchns, 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- 

 rufescentihus, anfractu ultimo cingula macularum ocellatarum 

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

 dentem validum prominentem acutum desinente. 



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



Alcyna lepida, A. Adams. 



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

 tibus transversis circumcincta, apice nigricante ; anfractibus 5, 

 planiusculis ; callo parietali in dentem parvum acutum desineute. 



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 ample, margine crenulato. 



I have dedicated this genus 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 Zizijphinus with the inner lip reflexed ; in form it also 



approaches many species of Gibhida, 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 depresse-cenica, prefunde umbilicata ; anfractibus o\, con- 

 vexiusculis, liris transversis granulosis (iuterstitiis oblique longitu- 

 dinalitcr striatis) ornatis, anfractu ultimo ad peri{)heriam carina 

 erenulata })rominente cincte ; apertura subquadrata, labio in 

 medio reflexo, labro intus Ifevi, basi liris concentricis granulosis 

 confertis iustructa; umbilico mediocri. Colore pallide fusco, ma- 

 culis ratliantibus fuscis ornate. 

 Bab. Off Mino-Sima; 63 fathoms. 



This appears to be the most abundant species but all the
