Phasianella nebulosa, Lamarck, Anini. sans vert. vol. ix. 

 p. 244 



Hab. Honduras. 



Allied to L. imdulata, but of less solid growth, more 



ventricose, and wanting the characteristic violet columella 

 of that species. 



Species 56. (Fig. a, b, Mus. Cuming.) 



Littorina irrorata. Litt. testa acicminato-ovatd, soli- 

 diusculd, anfractibus superne mbimpressis, deinde ro- 

 tundatis, undique valide spiraliter liratis, liris confer- 

 tis, interstitiis profundi excavatis ; livido-plumbed aid 

 nigricante, liris cceruleo-albidis, rufo puitctatis ; aper-

 cavato-dilatald. 



The bedewed Littorina. Shell acuminately ovate, 

 rather solid, whorls slightly impressed round the 

 upper part, then rounded, everywhere strongly spi- 

 rally ridged, ridges close-set, interstices deeply exca- 

 vated ; livid lead-colour or blackish, ridges bluish- 

 white, dotted with red ; aperture rather contracted,

 Phasianella sulcata, Lamarck. 



Hab. Sitka. 



Strongly ridged, of a grey colour, the ridges being 



roughened with red granules. 



Species 57. (Fig. a, b, Mus. Cuming.) 



Littorina ziczac. lAii. testa acuminato-ovatd, anfrac- 

 tibus deciivi-convexis, tenuissime lineari-sulcatis, in- 

 fe-rne obsolete angulatis ; kciescenfe-albd, pallide cine- 

 reo-carulescente, lineis rufis undatis oblique strigatd ; 

 aperturd subcontractd, fauce purpureo-fasciatd, colu- 

 melld subcallosd. 



The zigzag Littorina. Shell acuminately ovate, whorls 

 slantingly convex, very finely linearly grooved, obso- 

 letely angled at the lower part ; yellowish-white, 

 banded with pale ash-blue, obliquely streaked with

Troclms ziczac, Chemnitz, Conch. Cab. vol. v. p. fiH. pi. 

 166. f. 1599. 



Hab. Monte Christi, West Columbia. Kangaroo Island, 

 South Australia. 

 Notwithstanding the discrepancy in the al)ove-(juoted 



localities, the specimens bearing them, on good authority, 



are certainly the same species, agreeing precisely with the 



figure cited from Chemnitz. 



Fig. 58. (Mus. Cuming.) 

 The shell here represented, L. ttnebrata of Nuttall, 

 proves, on examination, to be merely a worn L. Pintado.
