DRYM^EUS, WEST INDIES. 27 



the species I have seen. Some of the St. Martin and St. Barts ex- 

 amples might also be called " anguillensis." It seems to be an ill- 

 defined or incipient subspecies. 



Red forms, both plain and banded, occur on Porto Rico (rare), 

 Tortola, Bonaire and Cura9ao ; also Guadaloupe and Martinique. 

 It is possible that the specimens from the latter two islands are an 

 importation. If so, the anomaly of the occurrence of virgulatus in 

 Cura9ao is even more accentuated ; but that island has also a species 

 of Cerion, a genus not occurring in the Caribbees, but common on 

 the Virgin Islands. 



Figs. 1-4 are from Porto Rico shells ; 5, 6, Anageda ; 7, 8, St. 

 Thomas; 12, St. Eustatius; 13-17, Tortola; 18, 19, St. Croix; 

 20-23, Anguilla; 24-26, St. Croix. 



D. MULTILINEATUS (Say). PI. 11, figs. 27-33. 



Shell narrowly perforate, oblong-pyramidal, solid; opaque white, 

 faintly blue- or brown-tinted, becoming purplish-blue on the earlier 

 whorls, irregularly obliquely streaked with chestnut, having a blackish 

 chestnut band below the suture and an umbilical patch of the same, usu- 

 ally with a basal band also, and often another narrow one a short 

 distance below the sutural band. Surface slightly shining, densely 

 but rather obsoletely striated spirally. Spire long, straightly conic, 

 the apex rather obtuse. Whorls 7, rather convex, the last decid- 

 edly so. 



Aperture oblique, oblong-ovate, streaked within, its length con- 

 tained nearly or quite 2^ times in that of the shell ; peristome simple, 

 broadly dark -bordered inside and out; columella concave, dilated 

 and sub-appressed above. 



Alt. 25, diam. 10.8 ; alt. of aperture 10 mill. 



Alt. 24, diam. 10.5; alt. of aperture 10.2 mill.
