and has a large, obtuse, romifled spiral fold above the middle. 

 There is also a slight, rounded angle, formed by the junction of the 

 columella with the lip in front. 



Length of the seven lower whorls, 18™'"; greatest breadth, 6'""' ; 

 length of body-whorl in front, 7-5™'" ; length of aperture, 4-5'""' ; its 

 breadth, 2 -5"'"'. All the upper whorls are broken off. 



Station 2228, in 1582 fathoms, one dead specimen (No. 44,791). 



This species most resembles 2\ Rathhuni, but it is larger, with 

 more flattened whorls, and has a distinct fold on the columella.

Shell not very small, short, stout and swollen, broad-ovate in form, 

 with a short spire, (the apex is eroded in both our specimens). The 

 body-whorl is large, swollen, and constitutes the greater part of the 

 shell. The suture is deeply impressed or slightly channeled, the 

 whorl just below it rising abruptly with a convex outline. The pen- 

 ultimate whorl is short, convex, and is surrounded by about three or 

 four punctate grooves. The body-whorl is strongly convex, but 

 very slightly flattened in the middle, its upper portion decidedly 

 swollen ; it is covered by about twenty well-marked, revolving 

 grooves, which are closely and very distinctly punctate, the puncta- 

 tions arranged very close together or in contact, and nearly uniform 

 in size; the intervals between the gi'ooves are rather broad and even, 

 with a somewhat lustrous, nearly smooth surface, crossed by slightly 

 sinuous lines of growth. The aperture is ear-shaped, rather broad, 

 narrowed and rounded at the posterior angles, broadly rounded in 

 front, with the inner margin sinuous and strongly excavated at the 

 base of the columella, on which there is an oblique, slightly elevated, 

 obtuse fold. Our S2)ecimens, both of which are dead, are white. 



Length of the largest specimen, consisting only of the last two 

 whorls, 8""™; breadth, G'S"'™ ; length of the last whorl, 7-5'"™ ; length 

 of aperture, 6-2'""^ ; its breadth, 3""".
