reflected ; body with a wash of transparent callus, which is 

 continued on the pillar as a thin elevated lamella continuous 

 with the left-hand margin of the rather elongated and re- 

 curved canal ; siphonal fasciole imbricate ; interior of the aperture 

 white, showing the color bands. Lon. of shell, 31.5 ; of last whorl, 

 23; of aperture and canal, 18; max. lat. of shell, including varices, 

 12.5 mm. 



Station 4784, in 135 fathoms, off Attu Island, Aleutians, June 

 11, 1906. U. S. Nat. Mus., 110,501. 



A very elegant and delicate species. 



Genus METULA Adams 

 METULA ELONGATA Dall, n. sp. 



Shell elongate, slender, cancellate, white, with seven or eight 

 slightly, convex whorls, with a minutely channeled suture; apex 

 defective, subsequent whorls minutely regularly wholly cancellated 

 by small flatfish axial and spiral threads ; the sculpture is a little 

 stronger just in front of the suture and on the canal, elsewhere prac- 

 ically uniform ; aperture long and narrow, with a shallow posterior 

 sulcus ; both lips thickened, the outer more or less crenulate ; pillar 

 straight; canal short, wide, slightly recurved. Lon. of shell (with- 

 out the nuclear and apical whorls), 35; of last whorl, 23; of aper- 

 ture, 16; maximum diameter last whorl, 9.5 mm. 



Station 5071, in 57 fathoms, south coast of Nippon, Japan, Octo- 

 ber 15, 1906. U. S. Nat. Mus., 110,502. 



Resembling M. mitrella Adams and Reeve, but much larger and 

 of different proportions. 



Genus GALEODEA Link (CASSIDARIA Lamarck) 



GALEODEA LEUCODOMA Dall, n. sp. 



Shell large, thin, white, with a short conical spire, having seven 

 or more whorls ; nucleus lost ; subsequent whorls with the suture 

 minutely channeled, the whorl in front of it flat, sloping to a shoulder 

 formed by the first of four prominent straplike, prominently nodulous 

 spirals (two of which appear between the sutures on the spire), 

 which are separated by wider interspaces ; on the last whorl there 

 are about 25 of these similar and equal nodules ; following these four 

 there is a series of about 17 more similar but not nodulous spirals, 

 which gradually decrease in size and approach each other more 

 closely, until they are reduced on the canal to mere threads ; be- 

 side these the interspaces have numerous smaller subequal spiral
