It can only be compared with A/urex Thomast Crosse, its nearest 
ally, from which it is separated by the two intervarical tubercles, there 
being but one in Zhomast. The spiral lire are coarser and fewer in 
number in Z#omasi than in the new species. The spire of d¢tuberculatus 
is higher and the general aspect of the two shells 1s quite different. 
OcINEBRA WARDIANA, sp. nov. Pl. 11, Fig. 5. 
Shell fusiform, thick, rather solid of a cinereous color ; whorls five, 
rounded, crossed by numerous rounded, elevated, longitudinal ribs 
which are encircled by thread-like spiral lire; spire rather acute, 
outline of whorls rounded ; sutures impressed ; there are nine longi- 
tudinal ribs on the last whorl which are elevated and rounded ; these 
are crossed by about eighteen large, somewhat scabrous lines, with 
occasionally a finer line between ; aperture ovate ; outer lip rounded 
and thickened by the last longitudinal varix ; inner margin of outer lip 
provided with seven well-developed denticles ; collumella area covered 
by an extending callous, smooth ; interior of aperture light-rosy ; 
canal short, wide, closed, a little recurved; umbilicus closed, sur- 
rounded by a strong fasciole; color yellowish overlaid by a blackish 
epidermis. 
Alt. 14, diam. 7 mill. Aperture (excluding canal) alt. 5, diam. 3 
mill. Habitat: Awustralta. 
This is a pretty httle shell having a superficial resemblance to 
Ocinebra actculata Lam., but separated from that species by the more 
developed umbilical region, greater development of the tuberclks 
within the outer lip and in the less accuminate spire. The color of 
the two shells is quite different, that of acécu/ata being light rosy, 
while Wardtana is yellowish or cinereous. Wardtana is also a more 
robust species than acicu/atas, and the general shape of the two species 
is quite different. Unfortunately the apex is broken so that I am 
unable to describe that interesting and valuable portion of the shell. 
The habitat of Wardiana will at once separate the two species, 
aciculata being from the Mediterranean Sea and Atlantic coasts of 
Europe and the British Channel. The new species is from Australia. 
I take great pleasure in dedicating this interesting little species to 
Prof. Henry A. Ward, ot Rochester, New York, who has for many years 
been a student of conchology and who has collected in many por- 
tions of the world.
