16 PHILINE. 
obliquely truncate, the spire impressed, whorls 2. Aperture patul- 
ous, roundly truncate at base, the outer lip nearly straight in the 
middle, the posterior lobe projecting a little above the vertex ; col- 
umella equally emarginate. Surface conspicuously spirally strio- 
late, strix thick, opaque, formed of a series of many confluent im- 
pressions; lip edge slightly crenulated. Alt. 2 mill. Lateral teeth 
of radula having a distinctly serrate crest inside; no uncini; form- 
ula 1:01. (Sars). 
Lofoten, Norway, 120-200 fms.

The comparative solidity, strong sculpture and total lack of un- 
cini are characteristic. 
P. InFORTUNATA Pilsbry, n.n. PI. 5, figs. 12, 138. 
Shell very thin and pellucid, glassy, rotundly-ovate, slightly 
longer than wide, the base equably rounded; vertex obliquely 
truncate, narrow; spire distinct, impressed. Whorls 2. Aperture 
very large and spreading, the onter lip obliquely expanded, con- 
tinued above the vertex and forming nearly a right angle there. 
Columella deeply concave. Surface very smooth, rather shining, 
lacking spiral striz, the growth-strie arcuate and very delicate. 
Alt. 3 mill.

Philine vitrea G. O. Sars, Moll. Reg. Arct. Norvy., p. 298, pl. 26, f. 
8a, 6. Not P. vitrea Gould, 1859. 
Utriculopsis vitrea M. Sars, Nyt May. f. Naturvidens., 1870, xvii, 
p. 177, pl. 11, f. 15-18 (animal only, exclusive of shell, which= Dia- 
phana globosa, ef. Manual vol. xv, p. 286) ; Bidr. til Kundskab Chris- 
tianiafjordens Fauna, ii, p. 65, pl. 11, f. 15 (mot f. 16-18,= Diaphana 
globosa Lovén). Compare Broceer, Bidr. Krist. Moll. Fauna, p. 
40; Zool. Ree. ix, p. 141. 
The globose form, angularly produced upper lobe of the lip, and 
lack of spiral strize, are characteristic. The synonymy is not wholly’ 
satisfactory, but as I have not the means of settling it, I have been 
content to follow Sars’ view, which is that the elder Sars figured 
under the name vitrea the animal of this species and the shell of 
Diaphana globosa. His figures of the latter are copied for com- 
parison on pl. 3, f. 44,45, 46. See preceding volume, p. 286.
