MELVILL AND STANDEN: SHELLS FROM LIFU. IIg 
Seven or eight specimens, but only one or two in good 
condition. Allied, though not very nearly, to D. /auta Adams, 
from South Australia, but much smaller and less shining. The 
compressions at the sutures are not so marked, and the lineation 
of the brown transverse marking more interrupted and not so 
broad. The opaque white tessellated ornamentation is not 
present in dauta. D. albugo Boog Watson, from Wednesday 
Island (‘Challenger’ Expedition) of which there are speci- 
mens also in J. C. Melvill’s collection from Thursday Island, 
from shell-sand collected there by Mr. Arnold Umfreville Henn, 
is also allied, though distinct. 
D. semistriata Phil. varia A. Ad.—Rare, and agreeing 
with authentic specimens from Adams marked ‘varia’ in 
J. C. Melvill’s collection. 
FAMILY R/JSSOL/JDAZ. 
Rissoina distans Anton. = R. canaliculata Schwartz.— 
Two specimens. 
R. minuta Neville.—One specimen, like 2. scolopax or R. sub- 
concinna, but only o°3 millimetres in length, may perhaps 
be placed here. (It is figured in Kuster’s Conch. Cab., 
Pl Xv-g 1185 12): 
R. scolopax Souverbie.—Many. Evidently common, and 
very beautiful. 
R. (Zebina) curta Adams.—Several. 
R. (Zebina) funiculata Souverbie. — Several. Perhaps 
identical with 2. spzévalis Souverbie, of which we have not 
seen specimens. 
R. (Zebina) subconcinna Souverbie.—Several. Resembling 
LR. scolopax Souv. 
R. (Moerchiella) spirata Sowb. —Two specimens of the 
type, and several of 
var. Lamberti Souverbie, 
var. Orbignyi A. Adams, and 
var. artensis Montrouzier.—This last a turreted form.
