like ribs arranged longitudinally down the shell. On the 
body whorl the ribs are twenty in number, and the spaces 
between them are perfectly smooth. The aperture is 
round, and about one-third the height of the spire.

EPITONIUM PHILIPPINARUM (epitonos, the back- 
stay of a mast; Philippi, the conchologist).—This Wentle- 
trap in most respects resembles the E. Jukesianum, but is 
slightly larger, being about five-eighths of an inch in length, 
and rather more than three-sixteenths of an inch in width 
at the base. These dimensions, although only varying so 
little, give the shell a more stocky appearance, which is at 
once obvious when a specimen is placed side by side with 
the more slender E. Jukesianum. The distinguishing feature, 
however, is that there are only ten ribs on the body whorl, 
and, consequently, the smooth interspaces are much more 
conspicuous. It is a pure white, very translucent, and 
polished. The mouth is slightly oval. Rather a rare 
species.

EPITONIUM TENELLUM (epitonos, the backstay 
of a mast; tenellum, dim. of tenuis, thin) —This Wentle- 
trap may be readily identified by its colour, being of a 
pale horn tint, with a narrow brown hand just below the 
suture and continued round the base. There is also a simi- 
lar coloured band winding spirally round the large cir- 
cumference of the body whorl. It is a much thinner 
shell than the other species, and is sculptured in a like 
manner, with longitudinal ribs, of which there are about 
twenty on the body whorl, the intervals being quite smooth. 
It is about seven-sixteenths of an inch in height, and has 
eight or nine whorls. A rare species. 
Found at the Bay of Islands, Auckland Harbour, Mount 
Maunganui, Ohiwa. 
EPITONIUM ZELEBORI (epitonos, the backstay of a 
a mast; Zelebor, the naturalist)—Although this Wentle- 
trap, popularly known as the Curly, is the commonest of 
the five species found in New Zealand, it is by far the most 
beautiful of these charming little shells. About an inch 
long, it is of an opaque snowy white, sculptured with longi- 
tudinal ribs and small transverse ribs in the intervals. The 
whorls are rounded, and they diminish gradually in size 
to the finely-pointed apex, the suture being well defined.
