Siplionorhis ehur, Morch. 



fvsiformis, Brod. 



Buccinum undatum, Linne. 



var, horealis, nov. nom., = var. pelagka, G. 0. Sars (but not 

 var. pelagica, King). Vadso, in shallow water. The nearest 

 approach to the form that we have in British seas is var. 

 Jltwuosa of Jeffreys, from Shetland, which it resembles in its 

 elongated form and flexuose ribs ; but the latter is a much more 

 delicate and in all respects more elegant form. 



var. ccerulea, G. 0. Sars. This variety is found at low water 

 at Vadso ; the substance of the shell is commonly of a rich 

 vinous-purple colour, which is especially evident on the columella. 

 Sars says of the colouring " fusco-cgerulea, faucibus intense 

 nigro-castaneis." The ribs are often almost entirely absent on 

 the lower whorls. It passes into var. horealis at a few fathoms 

 depth. 



var. Schieideri, Verkriizen. A beautiful pure white form 

 which comes up very constantly on the fishermen's lines at 

 Vardo. I have seen half-grown specimens which might pass 

 for the rare white variety of var. zetlandica ; but the form is 

 much less produced than in that variety from the Shetland 

 Haaf ; the whorls arc more tumid aud the ribs much more 

 developed. Occasionally pure white examples of var. zetlandica 

 occur ; but in the case of var. Schneideri the whole race is a 

 pure white one — at least, I did not see any similar specimens 

 of a different colour on the quay at Vardo. 

 Buccinum Jinmarchianum, Verkriizen. This beautiful species is 

 brought up in great numbers by the Vardo fishermen's lines ; 

 among a large number which I procured at Vardo there was 

 a single white specimen. I have an example in my cabinet, 

 kindly given me by Herr Schneider, which is no less than 

 80 millim. long ; it is referable to var. atienuata, G. 0. Sars ; 

 60 millim. may be considered as the ordinary limit of measure- 

 ment of a full-grown shell. Sars gives as measurement of 

 the usual form 55 millim., of var. attenuata 58 millim., of var. 

 scalaris "Long, usque ad 65 mm." 

 Buccinum groenlandicum, Chemnitz. Between tide-marks, Vadso. 

 var. nuda. I propose this name for a remarkable form of 

 Buccinum to be found on the outer side of the island which 

 shelters the harbour of Vadso. The form is more evenly conical 

 than groinlandicum, the whorls usually being flatter and the 

 suture less deep. In general the whorls are perfectly smooth, 

 without any trace of ribs, riblets, or puckers ; but in other 

 cases flexuous ribs are, more or less, developed on all the 

 whorls accompanied by spiral riblets, and the resemblance 

 to B. undatum becomes so exact that such a specimen 

 taken by itself might be ascribed by a conchologist as 

 being without doubt a small variety of that species. The
