spot is divided into two by a patch or band of whitish at the base of 

 the canal ; sometimes the middle spot is also divided into two, and 

 in other cases the posterior spot is as large as the middle one. There 

 is usually a faint, whitish revolving band at the shoulder and another 

 at the base of the canal. Interior salmon-colored. 



Length, 14""" ; breadth, 7-5""" ; length of body-whorl, 12">'° ; length 

 of aperture, 10'"'" ; its breadth, about 1""". 



Several perfect living specimens were taken by the Albatross, in 

 1883, at stations 2011 and 2012, in 81 and 66-5 fathoms, oif Norfolk, 

 Va. (Nos. 85,307 and 35,375.) Dead specimens were taken off 

 Martha's Vineyard by the Fish Hawk, in 1880 and 1881, in 64-5 to 

 100 fathoms. 



The occurrence, so far northward, of a large and well developed 

 species of this almost tropical genus is remarkable. It inhabits, how- 

 ever, only the warm zone along the inner edge of the Gulf Stream, 

 where it is associated with Solarium, Dolium, Avicida, and other 

 southern genera. 



This handsome species bears some resemblance to J/, carnea and 

 2L rosckla, from our southern coasts, in size and color, but differs 

 from both those species in having a much higher and more acute 

 spire, with all the whorls distinctly visible, and in the form and ar- 

 rangement of the plications. 



This species is also related to Mai'ginella limatula Conrad, of 

 which I have examined several specimens from the Miocene of Pagan 

 Creek, Va. The latter differs, however, in being a stouter and 

 broader-shouldered shell, with a much lower spire, in which the su- 

 tures are more concealed by the deposit of callus. The fossil form 

 is, therefore, evidently more closely related to, if not identical with, 

 M. apiclna* and M. rosckla, found in shallow water on our southern 

 and Gulf coasts, than to the present species. The number and posi- 

 tion of the plications on the columella and the crenulations on the 

 outer lip are the same as in 31. horealis. 



Volutella lachrimula Gould. 



Proc. Boston Soc. Nat. Hist., viii, p. 281, 1862 ; Otia Conch., p. 238. 

 Taken in considerable numbers at station 2109, off Cape Hatteras, 

 in 142 fathoms, by the Albatross, 1883. 



♦This form seems to me essentially identical with M. rtwiotda/w Kiener, of the West 

 Indies. It seems to me probable that both are identical with the fossil M. limatula. 

 M. roscida is probably only a local variety.
