ornata ; columella 4-plicata, antice torta, canali aperto ; aper- 
tura elongata; labro acuto, haud lirato ; labio nullo. 
Long. *8, long. spir. ‘4, lat. -3 poll.; div. 40°. 
Hab. Rosetta Head, Encounter Bay, South Australia (Coll. Angas). 
The specimens are all decollated, with a mamillate vertex. The 
locality was named by Col. Light, the first Surveyor-General, after 
Mrs. Angas, the author’s mother.

sub peripheriam ornata, marginibus spire rectis ; vertice nucleoso 
mamillato; anfr. norm. 6, medio angulatis, regione suturali 
concava; costis radiantibus circ. 8, validis, obtusis, rotundatis, 
supra et infra obsoletis, interstitiis concavis eas equantibus ; liru- 
lis spiralibus crebris, obtusis, supra costas transeuntibus, quarum 
circ. 12 in spira monstrantur, postice confertis minoribus ; 
canali curtiore, excurvato; apertura subrotundata; labro intus

Long. °54, long. spir. ‘27, lat. -28 poll.; div. 50°. 
Hab. South Australia (Coll. Angas). 
Resembles a Peristernia, but without the distinct fold of that 
genus. The broad brown belt is sometimes interrupted over the 
ribs, and is more or less dark according to the spiral sculpture. As 
the suture follows its middle, a part of the colour is seen on the 
spire, forming an elegant sutural line. 
5. COLUMBELLA INTERRUPTA, nob, (PI. II. figs. 9 & 10.) 
C. t. minima, fusiformi, levi, marginibus spire excurvatis ; vertice 
nucleoso naticoideo, prominente, apice mamillato ; anfr. norm. 5, 
subplanatis, suturis distinctis; livida, seu pallide viridi, lineis 
radiantibus creberrimis, angustissimis, a zonis interruptis, ele-

the shell.
