producing somewhat the effect of spiral striation, The mouth is 
subquadrate, with a lightly thickened white lip. Alt. 7°5, diam. 
max. 12mm. 
Fie. 1.—Dendrotrochus stramineus, n.sp. 
Hab.—Lo; Vanua Lava. 
Four specimens, three being immature, but all in good condition, 
from the former, and one dead shell from the latter locality. 
9. Draparnavpia WaLkert, n.sp. (Fig. IL.) 
T. sinistrorsa, anguste umbilicata, trochiformis, solidiuscula, oblique 
striata, apice subacuto; anfr. 6, plano-convexi, ultimus obsolete 
carinatus; apertura perobliqua, subovalis; peristoma tenue, margine 
externo subreflexo, columellari superne in laminam triangularem 
reflexo. Alt. 6°5, diam. max. 6mm. 
Hab.—Renée River, Espiritu Santo. 
At first I was under the impression that D. singularis (Pfr.), which 
is described as ‘‘ subacute carinatus,”’ had been misunderstood, and that 
the present form belonged there ; but since there 
exists in the British Museum a tablet of the form 
known under the name of s¢mgulards, bearing on 
the back, in Pfeiffer’s writing, the name and 
original locality, I have felt compelled to describe 
the species under consideration. It may be readily 
separated from D. singularis by its smaller size, 
RS UI Taapareandia and by its being only slightly, instead of strongly, 
Walkeri, usp. keeled; while, as compared with the specimen of 
Gassies’ D. turgidula, from his collection, and now 
in the British Museum, the present shell is a trifle more conic, while 
the whorls are flatter, and the suture not so deeply impressed. 
10. Pxacostytus Satomonts (Pfr.).
