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

 resembles E. contracta, Reeve. 



E. FUNICULATA, Reeve. 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. ovata, Pease (fig. 48), is a synon} r m. 



E. LINEATA, Reeve'. PI. 62, figs. 50, 51. 



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

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



Philippines, N. Australia, Viti Isles, etc. 



T'his is possibly the C. nana of Pillw., 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 sufficient^ 

 well-done to banish doubt on the subject. 



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

 name. 



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



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

 rupted by the ribs. Length, 13 mill. 



Galapagos Is. (Cuming); Viti and Paumotus Is. (Garrett); 



Solomon's Is. (Brazier); Aracan (Hanley). 



E. CONCINNA, Reeve. PI. ^3, fig. 54. 



Longitudinally flatly 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. 



Gagayan, 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, Reeve. 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.
