156 Mr. A. Adams on new Species of Mollusca 
tura angusta, antice producta ; margine columellari tenui, arcuato; 
jabro postice rotundato. 
Hab. Gulf of Lian-tung; Hulu-Shan Bay. 
Like H. brevissima and pygmea, A. Adams. An examination 
of the animal shows it to belong to Haminea, the genus which 
in'all probability includes its above-named congeners. In my 
Monograph of the family (Sow. Thesaurus, Bulla), they are 
arranged under Cylichnidz. 
3. Haminea strigosa, A. Adams. 
H. testa cylindraceo-ovata, utrinque rotundata, alba, nitida, sub- 
opaca, transversim tota minutissime striolata, longitudinaliter stri- 
gosa; apertura angusta, antice dilatata ; margine columellari sim- 
plici, arcuato ; labro recto, postice producto et rotundato. 
Hab. Tabu-Sima; 25 fathoms. 
White, with longitudinal slightly raised streaks, and entirely 
transversely striated. In form it resembles H. lucida, A. Adams ; 
but the aperture is rounded anteriorly, and not produced as in 
that species. 
Genus ScarpHanpER, Montfort. 
Five species only of this limited genus have hitherto been 
described from Europe and America; and I now add brief dia- 
enoses of six Asiatic species found by myself in the Sea of Japan. 
The shells, except to a person well acquainted with the family, 
might be mistaken for species of Philine, but are known by their 
distinct though sunken spire. They are also, being external 
shells, stronger and more distinctly sculptured; whereas the 
species of Philine are thin, more simple, and contained within 
the mantle of the animal. 
1. Scaphander japonicus, A. Adams. 
S. testa ovata, elongata, postice angustata, sordide alba, transversim 
‘ suleata, sulcis subconfertis puncticulatis ; spira occulta ; apertura 
postice coarctata, antice dilatata; labio tenui ; labro postice pro- 
ducto et obtusim angulato, antice rotundato; margine regulariter 
arcuato. 
Hab. Mino-Sima; 63 fathoms. 
The punctate strize are common to most of the species of this 
genus. The present species nearly resembles S. lignarius in 
form, but is much smaller (only half an inch long) ; it is also 
less ventricose, and the*transverse grooves are puncticulate. 
2. Scaphander Cumingit, A. Adams. 
S, testa oblongo-ovata, postice constricta, albida, transversim oblique
