 BY GEORGE W. TRYON, JR. 



1. M. RETIFERA, Tryon. — t. 22, f. 4. 



Description. — Shell ratlier thin, shining, turrited, narrow; 

 with four somewhat convex volutions (remaining) gradually 

 increasing in diameter towards the body whorl, closely encir- 

 cled by narrow engraved spiral stride; sutures distinct; aper- 

 ture small, oval, somewhat produced below; labrum regularly 

 curved, inner lip very much curved below ; columella without 

 deposit of callus. Shell chesnut-colored, with three narrow 

 red bands, which are exhibited upon the interior of the aper- 

 ture. 



Dimensions. — Length (of largest specimen) 23 millimetres, 

 breadth 9 mill. ; length of aperture 10 mill., breadth 5 mill. 



Habitat. — Hakodadi, Japan. 



My Cabinet. Cabinet of Academy of Nat. Sciences, Cabi- 

 nets of John G. Anthony and Chas. M. Wheatley. 



Observations. — Eather a showy species for the genus, resem- 

 bling the California type of Goniobases in general appearance. 

 It does not very closely resemble any Oriental Melanians; 

 perhaps its nearest analogue is Boninensis, Lea, which is simi- 

 larly sculptured, but is a narrower species, duller in color and 

 without bands. But very few Japanese Melanians have been 

 described, and none of them are allied to this species. 



2. M. BEUNNESCENS, Tryon. — t. 22, f 1. 



Description. — Shell shining chocolate-color or chesnut, with 

 two darker revolving bands, rather narrow, turrited; whorls 

 (four remaining) slopiugly convex, with prominent growth 

 lines, and close, slightly impressed revolving strife, which be- 

 come more distinct at the base of the shell ; sutures well im- 

 pressed; aperture obliquely oval, produced below; outer lip 

 flexuous, inner lip receding below, and white. 



Dimensions. — Length 28 millimetres, breadth 12 mill.; length 

 of aperture 11 mill., breadth 7 mill.
