/,'. ( 'i/jtraeoides, C. B. Adams, an unfignred species, is prob- 

 ably identical. 



E. ANGISTOMA, Sowb. PL 4, fig. 44. 



Swollen, smooth, brownish white. Length, 4 mill. 



East Indies (Reeve); Philippines (Cuming). 



The posterior elevation of the outer lip forming an angle at 

 its extremity nearly as high as the spire, is a distinguishing 

 feature of this little species. 



E. MINUTA, Reeve. PI. 4, fig. 45. 



Subglobose, transparent, glassy, white. Length, 1*5 mill. 



Philippine*. 



Dr. Weinkauff thinks it may be the young of the preceding 

 species. 



E. GALLINACEA, Hinds. PL 4, fig. 46. 



Pyriform, callous and angulated posteriori}', produced and 

 beaked anteriorly ; lip stoutly swollen, conspicuously produced 

 and sinuate at its posterior extremity ; white or brownish yellow, 

 sometimes with a superior, irregular band. Length, 6 mill. 



Philippines ; New Guinea; Torres Sts., Australia. 



Named from its fancied resemblance to a trussed hen. 



E. ANGULIFERA, Sowb. PL 4, fig. 47. 



Shorter, wider, more obtuse than E. yallinacea ; mouth 

 straight and linear, outer lip very broad and thick, its posterior 



elevation less pointed than in gallinacea. Length, 2 mill. 



Borneo. 

 E. COLUMBELLA, Menke. PL 4, fig. 48. 



Broadly pyriform, lip elevated behind above the spire ; yel- 

 lowish red or roseate. Length, 7 "5 mill. 



Mazatlan to Santa Barbara, Cal. 



E. marginata, Morch, found at 100 fathoms at Bocorones I., 

 near Panama, is probably a synonym ; and I suppose that the 

 shell described by Carpenter as E. Mauyerise var. Panamensis is 

 its exact equivalent. Neither of these species has been figured. 



E. VITELLINA, Hinds. PL 4, fig. 49. 



Obesely ovate, aperture rather wide ; dark red, lighter on the 

 thickened lip-margin. Length, 12 mill. 



Acapulco to Southern California. 



The largest species of the genus.
