the deep-water fishermen in this (the Northumbrian) coast. Two 

 of them had the animal in, and one which was alive I had in my 

 possession for a day or two, but the animal was in a very sickly 

 state, and never showed itself out of the shell. It was of a pale 

 flesh or salmon colour, without markings. Its form, which I 

 have only had an opportunity of examining in spirits, does not 

 appear to differ from that of Buccinum undatum, though the 

 operculum, which is rather small, has an apical nucleus, in that 

 respect resembling Fusus rather than Buccinum. The characters 

 of the species are, upon the whole, rather anomalous."

The recent capture, by Mr. Barlee, of several living individuals 

 of this species, in various stages of growth, enables us both to 

 amend our former description, and to illustrate the species by a 

 better engraving. Immature specimens (those with six volutions; 

 the adult have seven at the least) which are excessively fragile, 

 display the characteristic painting more vividly than the full- 

 grown shells. The ground-colour of the shell ranges from pale 

 fawn to light purplish chocolate, shaded lengthways with a more 

 intense tint at the stages of increase, and, for the most part, 

 irregularly flecked here and there with white. It is variegated 

 also by several narrow fillets of a darker hue, which sometimes 

 are interruptedly articulated by paler intervals : sometimes are 

 simple spiral lines. These bands, which are not generally very 

 clearly denned, and are usually about five in number upon the 

 penult turn, are wont to be grouped upon the body whorl, so as 

 to form two broad ribands, one near the anterior extremity, the 

 other midway between the former and the suture. 



Some of our specimens are more elongated than the one for- 

 merly delineated, and the spiral sulci are very decidedly nar- 

 rower than the intervening spaces ; no vestige of longitudinal 

 undulations is perceptible in any of them. The columella, which 

 in the aged shell is pure white, and destitute of callosities or folds, 

 is marked in those barely adult with a very oblique brown one ; 

 it decidedly exceeds the posterior portion of the inner lip in
