by the author. Probably no two naturalists could be found who would agree on the systematic place or relations of all the forms of Arctic Buccinide which have been described. But we have not seen any discussion of them with which we felt a more general accordance than that in Mr. Friele's work. In regard to the general relations of the group we feel that the limits of Troschel in this, as in many other cases, are too narrow, and his distinctions for family rank too refined and too exclusive. In dental, as in other characters, the time is at hand for naturalists, who may not yet have done so, to realize that easy transitions from one group to another exist in a majority of cases and may be found by sufficient search. The gen Ls Jumala of Friele, bears somewhat such a relation to Stroinbella Gray, as Liomesus Stimpson, does to some forms of Sipho. The median plate of the radula is edentulous. In this it agrees with Beringius Dall (1 879), and a doubt arises as to their distinctness from each other. The type of Beringius is Clirysodomus crebricostatits Dall, from Alaska. The only criticism which occurs to us relates to one of the figures. We doubt extremely whether the o6theca figured as belonging to Buccinumn terra-nove Beck (PI. iII, f. i6, a-b), does not rather appertain to a Neptunea, as it resembles precisely that of several small forms of Neptunea allied to despecta, familiar to us in the northern seas, while we have never met with oatheca of such form belonging to a true Buccinum. -Wr H.
