Hnh. Sandwich Islands. 



None of the specimens from the Sandwich Islands, which I have 

 seen, ajipear to be quite as large as those from St. Helena. The 

 former have a rosy apex to the spire, whilst in the latter it is pale. 

 Dr. von Martens (Don. Bisni. p. 4S) considers this species the same 

 as Collonia verruca, Gould. The difference in size and colour at 

 once distinguishes them. Some of the St. Helena specimens are 

 coloured like the type-forms, whilst others are reddish brown, with 

 a few pale interruptions on the spiral ridges. 



Turbo (Collonia) admissus. (Plate XXII. fig. 4.) 



Testa minuta, anguste umhilicata, eonico-globosa, alba, radiativi 

 rvfo-fusco lineata vel flammulatn, pi/ncfis rvfis minutis 

 tessellata ; anfractus 5, sivperne declives, dein angulati, ad 

 angulum carinati, liris temtihus paucis cincti, nltiinus infra 

 medium subanqulatits, carina circa umlilicum instructus ; 

 apertura svbrotundata, longit. totius h adceqiuins ; columella 

 arcuata, alba, levifer rejlexa. 

 Longit. 2k millim., diam. maj. 2. 



The generic position of this pretty minute species is at present 

 somewhat uncertain, as the operculum is tmkuown. On account of 

 its .<mall size and non-nacreous interior, I believe it to belong to 

 Collonia. One specimen is of a pinkish tint, and all show a more 

 or less distinct darkish zone on the lower surface of the body-whorl. 

 The minute dots fall upon the fine spiral lirae.

Hab. Jamaica. 



The coloration of this species is variable, but the " fine, rather 

 distaiit, parallel, spiral lines of brown, which descend more rapidly 

 than the whorls," appear to be quite constant. In young fresh 

 specimens more or less spiral striatiou is discernible.
