246 GIBBULA-MONILEA. 



umbilicus wide, perspective, the margin crenulated ; color whitish, 

 radiately painted with patches of reddish-brown. (A. Ad.) ' 



Off Mino-Sima, Straits of Korea. 63 fms. 



E. speciosa A. Ad. Ann. and Mag. N. H. 1860, p. 409. 



This species is more depressed and more widely umbilicated than 

 Enidajaponica, and the whorls are rather concave at the upper part ; 

 the granular lirse are wider apart, and the'oblique stride of the inter- 

 stices coarser. (A. Ad.) 



G. GEMMULOSA A. Adams. Unfigured. 



Shell depressed-conical, broadly umbilicated, sutures profoundly 

 canaliculate; whorls rounded, ornamented with close transverse 

 series of squamiform granules, 5 on the last whorl; whorls above 

 at the sutures delicately plicate ; aperture rounded-quadrangular ; 

 inner lip excavated and deeply reflexed in the middle ; outer lip 

 thickened and sulcate within, its margin crenate ; base somewhat 

 convex, bearing 4 series of squamiform granules ; umbilicus pro- 

 found, margin crenate. (A . Ad.) 



Off' Mino-Sima, Japan. 63 fms. 



Enida. gemviulosa A. Ad. Ann. and Mag. N. H. 1860, p. 409. 



This granular species differs very much from the two last de- 

 scribed, but partakes of all the characters of the genus, the scale- 

 like granules arranged in transverse rows are very peculiar. 'Ihe 

 a])erture is nearly circular, and beautifully nacreous and pearly 

 WMthin ; otherwise this shell might by some be mistaken for a 

 species of Echinella. (A. Ad.)

Shells of the genus or subgenus Monilea have a more or less 

 developed callous ridge or funicle revolving on the inner side of the 

 whorl within the umbilicus, and terminating at the columella, the 

 edge of which is reflexed over it. The outer surface is spirally 

 striate or Urate, and closely obliquely striated. The Indian Ocean 

 is the habitat of most of the forms, but some are found in the Pacific. 

 The outer lip is usually Urate within, and the columella more or less 

 obviously crenulate on its edge. The shell is heavy and strong ; but
