measure alt. 33. diam. 14, length of aperture 16 mill.; the ordinary 

 size of the species being, alt. 25, diam. 12, length of aperture 12 mill. 



Of Dominica specimens collected by Ramage, Smith writes: 

 " Three specimens from Dominica are very different in colouring 

 from the type as figured by Delessert (Recueil, pi. xxvii, fig. 3}. 

 They are of a warm reddish-pink color, banded with purple-black. 

 The upper whorls exhibit two bands, one just beneath the suture and 

 the other, a trifle broader, rather below the middle. The body-whorl 

 has a third zone beneath the centre somewhat narrower than the one 

 above it. The fine spiral striae correspond with those of the typical 

 form, and the minute pitting of the dark apical whorls is the same." 



Var. alMcans Maze. Shell entirely white except the earlier three 

 whorls, which show faintly three brown bands. 



St. Pierre, Martinique, at 200 meters alt. 



Var. christopheri Pilsbry, n. v. PL 13, figs. 98, 99. 



Similar to D. multifasciatus in texture and sculpture, but without 

 pink markings, the fourth band with a light-brown border above, the 

 same tint also appearing around the fifth band and sometimes above 

 the third; spir< j , stouter, with somewhat convex lateral outlines; 

 aperture longer, less rounded ; umbilicus more open. 



Alt. 25, diam. 12J, length of aperture 12J mill. 



St. Christopher (Swift, Bland). 



There is also a clear lemon-yellow tinted whitish form of this vari- 

 ety, agreeing with the banded specimens in contour. Bland has 

 already reported it from St. Christopher under the name Bulimus 

 multifasciatus. 



W. G. Binney has described the jaw and radula of a shell from 

 Antigua, which he refers to Liostracus multifasciatus (Ann. N. Y. 

 Acad. Sci. iii, p. 121). 



D. LATICINCTUS (Guppy). PL 13, fig. 94. 



Shell perforate, conic-elongate, thin, fuscous or yellow, shining, 

 decussate, zoned by four dark chestnut bands, of which two are visi- 

 ble on the upper whorls, the second (reckoning from the suture) be- 

 ing the widest. Whorls 6, a little convex, regularly increasing, the 

 last about two-thirds the length of the shell; spire elongate, the apex 

 acuminate. Aperture semi-oval ; peristome simple, acute, hardly 

 expanded ; columellar margin reflected over the narrow perforation ; 

 columella slightly twisted.
