by Mr. Gai^rett. Except in its mnch smaller size it much 

 resembles E. contracta^ Reeve. 



E. FUNicuLATA, Recve. PI. 62, figs. 48, 49. 



Shell short, obese, with longitudinal ribs cut into tubercles by 



revolving grooves ; black, interstices of the ribs yellowish. 



Length, 12-15 mill. 



Howland Isl. 



The principal distinctive character appears to be the short, 



obese form. E. orata, Pease (fig. 48), is a synonym. 



E. LiNEATA, Reeve. PL 62, figs. 50, 51. 



Shell short, ovate, solid, longitudinally nodosely plicated, white, 

 encircled b}- several lead-black narrow lines. Length, 11 mill. 



Philippines, N. Australia, Viti Isles, etc. 



This is possibly the C. nana of Dillw., which Deshayes con- 

 cedes to be the same as C. zonalis, Lam. The figure in Martini 

 referred to in the descriptions of these species is not sufficientl}' 

 well-done to banish doubt on the subject. 



Var. MACULATA, Pease (fig. 51), is scarcely entitled to a varietal 

 name. 



E. ZONATA, Reeve. PI. 63, fig. 52. 



White, with dark chocolate or black bands, sometimes inter- 

 rupted by the ribs. Length, 13 mill. 



Galapagos Is. (Cuming); Viti and Pa umotus Is. (Garrett); 



Solomon's Is. (Brazier); J^r«ca/i (Hanley). 



E. CONCINNA, Reeve. PI. 63, fig. 54. 



Longitudinally fiatly ribbed, ribs very finely noduled, white, 

 conspicuously encircled with brown bands in which the nodules 

 are white, edge of the lip orange-red. Length, 15 mill. 



Caguyan, Isl. of Mindanao, Philippines, 



under stones at low water (Cuming). 

 Much resembles the preceding species, and is, perhaps, only 

 a slim variety of it. 



E. ARMiLLATA, Rcevc. PI. 63, fig. 59. 



With a nodulous keel on the upper part of the whorls, 

 nodosely ribbed beneath, interstices smooth ; whitish, the nodules 

 alternately white and black in zones, nodules of the keel 



yellowish. 



Isl. of Ticao, Philippines,
