upper spire. These are the whorls stained chestnut, so dark as 
to be almost black, in the New Caledonian specimens. The larger 
whorls are closely corded by spiral lyre, having smaller lyre in 
their interstices. Weak, longitudinal ribs undulate the central 
whorls and appear on the last whorl, but vanish there before 
reaching the periphery. The columella lip is broad and reflected, 
obliquely ridged within and sharply bent above. The aperture 
is perpendicular, ovate and grooved within. 
Rissoa joviana of Melvill and Standen* appears to me to be an 
absolute synonym of Alaba fulva, Watson.t These and Alaba 
striata, Watson{ should enter the same genus as pyrrhacme. 
Indeed I am not satisfied that all four names do not apply to 
aspects of one polymorphic species. 
SCALA REVOLUTA, Sp. nov. 
(Fig. 7). 
Shell minute, white, with smooth coiled apex 
and variced, solute, subsequent whorls. Whorls 
six, of which the apical three are smooth and in 
contact, the fourth commences to uncoil and the 
remainder are widely separate. Varices eight 
on the last whorl, with an anterior corner, 
slightly elevated ; between the varices the shell 
is smooth and glossy. Aperture broken in the 
type example, but apparently circular. Length 
3, breadth 1-5 mm. 
One specimen from the lagoon beach. 
The only shell for which the novelty might 
be mistaken is S. hyalina, Sowerby. Judging 
from Sowerby’s drawing§ that differs by being 
much larger, broader, uncoiled to the tip, though less apart 
latterly, and by more numerous and serrate varices.

SCALA PAUMOTENSIS, Pease. 
Tryon, Man. Conch. ix., 1887, p. 65, pl. xiii., fig. 16. 
Four specimens from the lagoon beach. Cited by Tryon from 
Fiji, Gilberts, and Paumotus. 
SCALA SUBAURICULATA, Sowverbie. 
Tryon, op. ci., p. 67, pl. xiv., figs. 21, 22. 
Four specimens from the lagoon beach correspond fairly well 
with New Caledonian examples.
