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, strise 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 1-0-1. (Sars}. 



Lofoten, Norway, 120-200 frns. 



Philine cingulata SARS, Moll. Keg. Arct. Norv. p. 297, pi. 26, 

 f. 7a-c. 



The comparative solidity, strong sculpture and total lack of un- 

 cini are characteristic. 



P. INFORTUNATA Pilsbry, n. n. PI. 5, figs. 12, 13. 



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 striae, the growth-striae arcuate and very delicate. 



Alt. 3 mill.

Philine vitrea G. O. SARS, Moll. Reg. Arct. Norv., p. 298, pi. 26, f. 

 8a, b. Not P. vitrea Gould, 1859. 



Utriculopsis vitrea M. SARS, Nyt Mag. f. Naturvidens., 1870, xvii, 

 p. 177, pi. 11, f. 15-18 (animal only, exclusive of shell, which=ZKa- 

 phana globosa, cf. Manual vol. xv, p. 286) ; Bidr. til Kundskab Chris- 

 tianiafjordens Fauna, ii, p. 65, pi. 11, f. 15 (not f. 16-]8,=Diaphana 

 globosa Loven). Compare BROGGER, Bidr. Krist. Moll. Fauna, p. 

 40; Zool. Rec. ix, p. 141. 



The globose form, angularly produced upper lobe of the lip, and 

 lack of spiral strise, 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 pi. 3, f. 44, 45, 46. See preceding volume, p. 286.
