192 PLANAXIDA. 
These are of a rich brown colour and consist of seven whorls ; 
spire more acuminate than in the next form. 
7 Maré, Loyalty Islands ; ex c. F. Layard, Esq. 
It was, I suspect, one of the specimens from this locality, out 
of Mr. Hanley’s collection, that was figured by Sowerby in the 
Con. Iconica? They are almost quite black, of six whorls ; two 
have a peculiarly shortened spire and may belong to a distinct 
torm. 
Long. 12, diam. 7 mil. 
1 Camorta, Nicobars; coll. F. A. de Roepstorff, Esq. 
Long. 10, diam. 53 mil. 
Quite black, of six whorls; exactly resembles Sowerby’s 
fig. 13. 
17. Planaxis niger. 
Planaxis niger, Quoy, Voy. de l Astrolabe, 1832, New Ireland, anfr. 4— 
long. 4, diam. 2 lin., “spire courte, obtuse, corrodée, 8—4 stries a la 
base” ;=P. ahbreviatus, Pease, P. Zool. 8., 1865, Central Pacifie— 
long. 10, diam. 6 mil. 
It would almost seem as if the description and figures of 
Quoy applied to two distinct species, the former undoubtedly 
referring to this species and the latter resembling more closely 
the preceding (except the line denoting natural size, which 
refers to the former) ? 
5 Tahiti; coll. H. Pease (typical Pl. abbreviatus) and ex Mus. Godeffroy. 
1 Arakan ; coll. R, Hungerford, Esq. 
Long. 82, diam. 5 mil. 
Spire short, obtuse, and corroded; four whorls, 3—4 sulca- 
tions at base of the last whorl; jet black, with aperture much as 
in preceding specimens, denticulations being almost obsolete, but 
a good deal more developed than in Tahiti specimens, which 
also have the last whorl more tumid; tooth above columella 
‘yemarkably developed in this specimen, much as in fig. 12 of 
Con, Iconica.
