22 PHILINE. 



Philine velutinoides SARS, Moll. Reg. Arct. Norv., 1878, p. 302, 

 pi. 26, f. 10a-c. 



The wideness of the upper part is peculiar and unusual, and lends 

 much probability to the view that Utriculus ventrosus Jeffr. (Dia- 

 phana ventricosa Jeffr., Vol. XV, p. 284) may be the same. In 

 that case, velutinoides will become a synonym of Jeffreys' species. 



P. POLARIS Aurivillius. PL 3, figs. 39, 40. 



Shell very thin, fragile, pellucid, oblong-ovate ; whorls 3-4. Aper- 

 ture ample, expanded at base, contracted above, the outer lip more 

 appressed than in P finmarchica. Surface covered with spiral, very 

 delicate pairs of lines, scalloped chain-wise. Alt. 3, diam. 2'5-2 

 mill. Radula with the formula 2*1 P 0'1*2, laterals and uncini eden- 

 tulous, of equal length. (Auriv.). 



N. of Siberia, lat. 73 5', E. long. 144 20', and 73 28', 164 10', 

 8-9 fms. 



P. polaris AURIV., Vega-Exped. Vetenskapliga laklagelser, iv, 

 pp. 371, 380, pi. 12, f. 21, 22 (shell) ; pi. 13, f. 18 (radula). 



Shell has most similarity to P. finmarchica. but the radula is more 

 like that of P. quadrata except that the laterals apparently have 

 no serrate crest. A more proper grouping of the species geograph- 

 ically would bring it among the N. Pacific forms, but faunally the 

 Arctic Sea is allied more to the N. Atlantic. 



P. MEMBRANACEA Monterosato. 



I do not know that a description or figure of this form has been 

 published. The diagnoses of Mediterranean forms of Tectibranchs 

 and Polyplacophora in Cams' Prodromus Faunae Medit. are such a 

 maze of blunders that the work is not worth quotation ; but this 

 form is not mentioned therein. 



Coast of Algeria 207 fms. (Jeffr.); Gulf of Naples (Acton); 

 Palermo 60-90 meters (Monte.).

P. STRIATULA Jeffreys. 



Resembles P. punctata Clark in size, but differs in the spire, sys- 

 tem of sculpture and the more dilated aperture. (Monts.').
