Gehäuse ganz dünnschalig, fast durchsichtig, glatt, wenig glänzend, glasartig weiss. 
Es sind nur drei Umgänge vorhanden, die beiden ersten klein, leicht gewölbt, der letzte 
sehr gross und stark gewölbt; die Naht ist einfach, ziemlich tief. Die Mündung ist eiför- 
mig, oben spitz, etwa ^/g des Gehäuses einnehmend; die Spindel ist etwas schief, kaum 
gebogen, unten schräg und ziemlich plötzlich abgestutzt, oben durch einen sehr dünnen, 
über die Mündungswand ausgebreiteten Gallus mit dem dünnen, einfachen Mundrand ver- 
bunden. 
Aufenthalt an Kerguelen, in 4—5 Faden Tiefe auf Tang und Polyzoen gefunden. 
Sie gehört schwerlich zu Admete und ist wahrscheinlich unausgewachsen.

, Shell rather small thick and solid, short, stout, with coarsely ribbed and rudely nodulous, 
convex whorls. The spire is short and rapidly tapered, with the apex apparently blunt, but eroded 
in both of our specimens. Whorls apparently 4 — 5, the last 2 are strongly convex with a well im- 
pressed suture. The last whorl is surrounded by 5 rows of rather large and coarse prominent nodu- 
les, joined together by low revolving ridges and situated upon about 12 broad, low, rounded or wave 
Uke ribs. On the penultimate whorl the ribs are more prominent and continue across the whorl and 
bear about 3 rows of nodules. The aperture is short, broad ovate, more acute behlnd than in front; 
the canal is very short and broad flaring, widely opened and twisted a little to the left, but does 
not cause any interruption or constriction of the outer lip which is regularly archsd, forming neavly 
a semicircle and has a thin flaring edge, which is strongly thickened a short distance within the 
aperture, anteriorly the outer lip continues round in a regulär curve and joins the columella without 
a distinct notch; posteriorly there is a distinct rounded groove within the aperture at the junction of 
the lip with the body-whorl; the columella is strongly sinuous and twisted, its anterior margin forms 
a distinct ridge or fold and another similar fold is situated at about the middle; the inner lip is ex- 
cavated in the middle and is thickened by a layer of white enamel, which is continuous from the 
outer lip around to the anterior margin. No operculum. Colour white. — Long, 12, diam. 8 Mm.“ — 
Verrill, 
Admete nodosa Verrill Transact. Connect. VI. p. 419 pl. 44 fig. 9. 
Im Tiefwasser vor der Küste von Neuengland gefunden, meiner Ansicht nach wohl 
besser eine eigene Gattung bildend.
