M. festa acuminato-fusiformi, epidermide atro-fusca induta, 
levigata, obsolete striata, basin versus valide sulcata; spira 
acuta; basi leviter attenuata; anfractibus 9, subrotundatis ; 
apertura oblonga, carnea; columella rectiuscula, triplicata ; 
labio externo arcuato, tenui, minutissime crenulato; intus 
levi. 
Long. 33, maj. lat. 11; anfr. ult. maj. long. 21; apert. long. 16, 
lat, 4 mill. 
An acuminately fusiform Mitra, covered with a dark brown epi- 
dermis, nearly smooth, very obscurely striated, but strongly grooved 
towards the base; spire acute; base somewhat attenuated ; whorls 
9 in number, rather rounded ; aperture oblong, flesh-colour ; colu- 
mella nearly straight, three-plaited; outer lip arched, thin, very 
minutely crenulated ; interior smooth. 
Obs. A species quite distinct from any hitherto described ; it 
makes an addition to the Mitre with dark epidermis, such as M. 
orientalis, nigra, &e. 
7. OvuLuM pEpREssuM. (Plate XXIV. fig. 1.) 
O. testa elongata, angustata, depressa, antice producta, utrinque 
attenuata et bicuspidata, polita, minutissime striata, alba, ex- 
tremitatibus aurantiaco tinctis; bast concavo-depressa; apertura 
angusta, postice dilatuta. 
Long. 21, maj. diam. 5, min. 2 mill. 
Hab. North-west Australia (Capt. Denicke). 
A narrow depressed Ovulum, produced in front, both ends attenu- 
ated and terminating in two points, polished, very finely striated, 
white, tinged’ with orange at the extremities; base concavely de- 
pressed ; aperture narrow, rather more open towards the hinder 
part. 
8. ADMETE TABULATA. (Plate XXIV. fig. 3.) 
A. testa oblongo-turrita, spiraliter costata (costis planato-con- 
cavis), longitudinaliter obscure plicata, albida, epidermide pal- 
lide fuscescente induta; anfractibus 7, convexis, superne angu- 
latis, supra angulum subconcavo-depressis ; apertura oblongo- 
ovata ; columella rectiuscula, minute plicata. 
Long. 22, maj. lat. 10 mill., apert. long. 9, lat. 45 mill. 
Hab. Arctic Ocean. 
An Admete of an oblong turreted form, spirally ribbed, ribs slightly 
concave ; longitudinally obscurely plicated; whitish, covered with a 
pale brown epidermis ; whorls 7 in number, convex, angled above, 
concavely depressed above the angle; aperture oblong-ovate ; colu- 
mella nearly straight, minutely plicated. 
Obs. The species of the genus 4dmete (Miller), by some included 
in Cancellaria, are all northern; the type is 4. viridula (Gould) ; 
and the species at present known are A. crispa (Moller), couthoyi 
(Jay), grandis (Forbes), abnormis (Gray), borealis (A. Adams), 
and ciliata (Kriiger).
