Long. 24, diam. 24 mil. 
Of the usual “ turbinate” shape, consisting of four whorls; the 
apical two are smooth, the third has two prominent raised spiral 
keels, coarsely, nodosely reticulated; the last whorl convexly 
ventricose, with eight spiral keels, nodosely granulated and with 
the interstices longitudinally striate; umbilicus more open 
than in the Japan species, peristome slightly fimbriate. Dr. 
Hungerford has dredged a closely allied form at Hongkong.

Long. 1, diam. 1 mil. 
Turbinate, of 34 whorls, the apical ones smooth, the last but 
one with two raised spiral keels, the last with five. I can detect 
no longitudinal striation whatever, the interstices consequently 
appear to be quite smooth; behind the peristome, which does 
not appear to be fimbriate, there are two conspicuous, thickened 
labial ‘‘ varices”; the umbilicus open, much as in the preceding. 
Altogether a very distinct though so minute a form! The Red 
Sea specimen, which though also in good condition is probably 
scarcely adult, agrees exactly with the type, except in want- 
ing the characteristic “labial varices” and in that the peris- 
tome is distinctly fimbriate ; it also shows no signs (under the 
lens) of any longitudinal or reticulate sculpture. Named 
in honour of the late Mr. Henry Adams.
