shouklcr. The nucleus, which consists of four whorls, is chestnut- 

 brown in color, large, regularly tapered, very acute, the apical whorl 

 being very minute, but regularly coiled; the three lower nuclear 

 whoi'ls are very minutely decussated by two sets of very fine, oblique 

 lines. The aperture is long, rather narrow, with the posterior end 

 acutely angled ; the siphon is nearly straight, rather long and narrow. 

 The columella is nearly straight ; the outer lip curves strongly for- 

 ward in the middle and has a rather broad and deep, rounded sinus 

 situated a little below the suture. 



The entire shell below the nucleus is translucent bluish white in 

 live specimens, and the surface is lustrous. 



Length of the largest specimen, 52"""; breadth, 18™"'; length of 

 last whorl in front, 36""" ; length of aperture, 2V'""' ; its greatest 

 breadth, S'""" ; length of nucleus, 2'""\ 



The largest specimen, which was dead, occurred at station 2,230, in 

 1,168 fathoms (No. 44,650) ; a smaller, living specimen (No. 44,649), 

 was taken at station 2,222, in 1,537 fathoms. 



Tliis fine species is named in honor of Mr. George Gwyn Jeffreys, 

 the distinguished conchologist. 



Pleurotomella tincta Verriii, sp. nov. 



Plate XLIV, figure 4. 



Shell moderately large, somewhat stout, nearly regulai'ly fusiform, 

 rather thin, delicate and translucent in texture, in the living s))eci- 

 mens having a light chestnut-brown color and a lustrous surface. 

 The spire is rather short, rapidly Xapered, acute. The largest speci- 

 men consists of five whorls besides the nucleus, which apparently 

 contains about two and one-half whorls, but is eroded in both of our 

 specimens. 



The whorls of the spire have a distinct, nodulous shoulder and a 

 broad, sloping, concave subsutural band, occupying about one-half 

 the breadth of the whorls ; on the last whorl the shoulder is convexly 

 rounded and destitute of nodules, but is crossed by numerous, dis- 

 tinct, flexuous lines of growth which rise into distinct, sharply raised 

 riblets on the subsutural band just below the suture; the surface is 

 also covered, except on the subsutural band, by numerous small, 

 regular, sharply impressed grooves, which appear a little wavy or 

 crinkled, owing to the crossing of the lines of growth ; the grooves 

 are separated by smooth, flattened interspaces exceeding their own 

 width. On the |)receding whorls the nodules on the shoulder are
