" 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 umbilicated Ziziphinus 

 with the inner lip reflexed ; in form it also approaches many species 

 of Gibbiila, 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." (A. Adams.) 



G. JAPONICA A. Adams. PL 67, figs. 44, 45. 



Shell depressed- conical, profoundly umbilicated ; whorls 5 J, slightly 

 convex, ornamented with transverse granulose lirse, the interstices 

 obliquely longitudinally striated ; last whorl encircled by a promi- 

 nent crenulated carina at the periphery ; aperture subquadrate, in- 

 ner lip reflexed in the middle, outer lip smooth within ; base with 

 close granulose line ; umbilicus moderate ; color pale brown, orna- 

 mented with radiating brown patches. (A. Ad.)

This appears to. be the most abundant species, but all the speci- 

 mens I obtained in the dredge were dead shells. In this species 

 and E. speeiosa the inner lip is smooth within, but in E. gemmulosa 

 it is internally thickened and lirate and crenate at the margin ; in 

 E. japonica the aperture is also less circular in its outline. (A. Ad.) 



G. SPECIOSA A. Adams. Unfigured. 



Shell depressed-conical, broadly umbilicate ; whorls 4?, nearly 

 flat, angulated at the sutures, with rather close transverse granulose 

 line, the interstices elevately, obliquely striate ; last whorl orna- 

 mented on the periphery with a deeply crenulated rib ; aperture 

 oblique, quadrate ; inner lip straight, broadly reflexed in the middle ; 

 outer lip angular at the suture, smooth within ; sutures canaliculate ; 

 base ornamented with granulose line alternately large and small ;
