500 On new Marine Mollusca from Japan. 
This pretty little shell bears some resemblance to Minolia 
strigata, mihi, from which, however, it differs very consider- 
ably in detail. The angles are less numerous and less 
prominent, the longitudinal strise are much more distinct, 
the umbilicus is wider and decussately crenulated within and 
on the border. 
Ethalia floccata, sp. n. 
Testa depresso conica, solidiuscula, polita, late et profunde umbilicata, 
albida, lineis fuscis numerosis obliquis et angulatis maculisque 
fuscis et albis picta; spira paulo elevata, convexiuscula ; anfrac- 
tus 5, leviter convexi, leves, sutura impressa sejuncti; anfractus 
ultimus ad peripheriam obtuse angulatus, ad basim convexus ; 
umbilicus latus, plicatus, intus obtuse angulatus; apertura oblique 
subquadrata, intus argentea, peristoma simplex, callo columellari 
angustiusculo superne effuso. 
Alt. 4, lat. 8 millim.

This pretty shell has somewhat the form of EF. carneolata, 
Melv., but more angular, and with a wider open umbilicus. 
It is smooth, with only the faintest trace of obsolete spiral 
lire ; the colour-markings are characteristic, consisting of 
oblique and acutely angulated brown lines running from the 
suture and brown spots in the middle of the whorls and at 
the periphery, while the base is rather curiously flaked with 
opaque white. ‘The narrowness of the columella callus, 
scarcely overlapping the widely open umbilicus, seems to 
place this species on the confines of the genus. 
Tellina consanguinea, sp. 0. 
Testa elongata, compressa, tenuiuscula, nitida, rosea, postice 
acuminata, leviter flexuosa, antice rotundata; umbones acuti; 
margo dorsalis anticus longus, vix declivis, posticis brevior, 
triangulatus, area angusta, acute lirata; valva dextra concen- 
trice et radiatim tenuissime striato-sulcatim decussata, striis 
radiantibus posticis conspicuis, anticis obsoletis; valva sinistra 
undique leevior. 
Alt. (umbono-marg.) 22, lat. (antero-post.) 52, diam. 8 millim, 
Hab. Hirado Higen. 
This shell bears some resemblance to 7’. vulsella, Chemnitz, 
from which it differs chiefly in its less attenuated form, 
shorter beak, and somewhat more solid substance, 
Cardita abbreviata, sp. n. 
Testa subcordata, crassiuseula, leviter inflata, pallide straminea, 
radiatim costata, costis 16 rugosis, crassis, confertis ; umbones
