542 MR. E. A. SMITH ON MARINE SHELLS 



caudam denticulata; canalis angustus, recurvatus. Longit. 8 mill., 

 diam. 3^ . 



Hab. Strong Island, Caroline group. 



The coloration of this pretty species is very characteristic. 

 The ground-tint varies from white to yellowish ; the spiral inter- 

 rupted line is situated rather above the middle of the whorls ; and 

 the dark olive-brown lines or flammulatious are very irregular 

 and flow into one another, thus forming an irregular network. 

 The ultimate whorl is encircled by a white zone at the obtuse 

 ano-ulation near its middle, and at the spiral interrupted line it 

 is also very faintly keeled. The base of the columella is furnished 

 with five or six nodulous lirations ; and the tooth-like lirse within 

 the labrum are about eight in number.

 {Cuming). 



The transverse lirse are three in number in the upper whorls, 

 and about eleven in the last. On the labrum there are five or 

 six denticles ; and the middle of the columella is very prominent. 

 The backward slope of the outer lip and canal is very remark- 

 able. 



21. E. zoNATA, Reeve. — Ricinula zonata. Reeve, Conch. Icon. iii. f. 33. 

 Hab. San Cbristoval, Solomon Islands (Brazier) ; Gallapagos Islands 



(Cuming). 

 If the Cumingiau habitat be correct, then this species is very 

 widely distributed. The shell from the Solomon Islands is yellow, 

 with black bands, and the short black longitudinal stripes at the 

 base are very constant, and the whole surface of the shell is 

 minutely reticulated with the finest longitudinal and spiral stria?. 

 The labrum is thickened within and without, and bears seven 

 small teeth ; and the columella is furnished with about twelve 

 short transverse lirse.

The ribs on the last whorl of this species are about ten in 

 number and are continuous to the base ; and the spiral ridges, 

 which are tubercular on crossing the ribs, amount to 9, including 

 the row of the yellow tubercles beneath the suture. The nodules
