Has near allies in the Australian M. multisulcata Harris,* and especially 
identical, except for the apparent absence of punctures in the New Zealand 
shell. The Australian shell, however, seems to differ in its smaller protoconch 
(“two small, narrow, rounded turns ") and in its dimensions, being much 
more elongate and having a spire higher than aperture. Harris (Cat. Tert. 
Moll. Brit. Mus., pe hoy 120) gives the dimensions of an Australian 
specimen аз — height, 66mm.; diamet ter, 16mm.; height of aperture, 
28 mm. The new species is also not so markedly angulate on periphery. 
, Mitra elatior n. sp. (Plate 50, figs. 5a, 56.) 
Shell in form and sculpture so close to the previous species that 2 is 
best described by comparison with it. Protoconch narrower and er 
and apparently has an extra turn. First whorl with 5 spirals, cris 
later to 6 and then 7 on penultimate whorl; body-whorl with about 20 
unequal spirals. Interstices vary from one- -half to one-third of ribs in width 
on periphery, but almost as wide as ribs on base; ribs as in previous species. 
The shells are not worn, and interstices are finely punctate, due to presence 
of axial threads which do not appear on ribs; thus it is probable that well- 
preserved specimens of M. eusw would show punctation also. Shell is 
noticeably narrower than in that species and more elongate, shape being 
narrowly fusiform rather then biconie. Whorls are also much more loosely 
coiled, the tightly-wrapped appearance of М. cusulcata being absent. 
Body-whorl has no blunt angulation, but is very lowly convex and then 
contracted to beak much lower down than in the other species, The presence 
of the perfectly straight supra-peripheral area in M. euswleata makes the 
spire-area almost a plane surface, hardly interrupted за sutures, but in 
M. elatior convexity of pommes makes Age ccc appear distinctly incised, 
although он of spire remain strai Spire is also considerably higher 
than nternally, columella ad 5 plaits instead of 4, the прег:
