286 A. S. PACKARD, Jr., ON THE RECENT 



each whorl removed much nearer the middle than is usual ; spine acute, longer than the body 

 of the shell, suture not deeply impressed ; aperture long ovate ; columella smooth, a little 

 flattened, regularly concave, not plicated ; canal very short, oblique; the body of the shell 

 covered with revolving lines and slightly waved longitudinal plications, which are especially 

 marked on the spine. Length, .48 ; breadth, .20 ; length of aperture, .22 inch. One spec- 

 imen was dredged in fifteen to thirty fathoms at Square Island. Found fossil at Cari- 

 bou Island; rare. The typical forms are found on the whole coast. 



Bela nobilis (Moller). 



This species differs from B. americana and B. turricula (of which we would scarcely con- 

 sider it a variety), in its fewer and larger rugSB, with less distinct revolving lines. 



Bela scalaris. 



Defrancia scalaris Mull., Index MolL Gronl. 



This shell we would consider as also distinct from B. americana, and like that species it 

 has both a short and elongated form. The canal is longer and the spine is more acute. 

 The fossil specimens scarcely differ. Specimens from Dr. Loven, thus labelled, were kindly 

 loaned me by Dr. A. A. Gould for comparison. Square Island, thirty fathoms, shelly bot- 

 tom ; and also at Dumplin Harbor, Sandwich Bay, in four fathoms. 



Bela woodiana Moll. 



Fusus harpularius Gould. 



It is a shorter and thicker shell than the preceding, in which the first whorl is as long as 

 the remaining ones together. Not common, though a very abundant fossil. 



Bela exarata. 

 Defrancia exarata Moller. Pleurotoma rugulatus " Moll." Reeve, Icon. Conch, fig. 345. 



In this species the first whorl is longer than the rest ; the canal is shorter and the aper- 

 ture rounder. The longitudinal ridges are the same in number as in B. woodiana, but are 

 less prominent, while the revolving lines are much coarser, giving the surface a reticulated 

 appearance. Common on the whole coast. 



Bela decussata Stimps. 



Common in Salmon Bay in ten to fifteen fathom, smud, where it occurred more abun- 

 dantly than elsewhere on the coast. Square Island in thirty fathoms, shelly bottom. 



Bela pleurotomaria Stimps. 



Fusus pleurotomarius Couth. Defrancia Vahlii Beck. 



Dredged at a depth of thirty fathoms Square Island ; of four fathoms at Sandwich 

 Bay.
