238 SCAPHANDRID^E, PHILINID^. 



closely placed. Aperture largely embracing, lengthened, narrow 

 and subangular at base, which is longer than spire, more dilated 

 and rounded above ; columella narrow, elevated, a little twisted, the 

 lower columellar margin strongly convex toward its middle ; umbil- 

 icus small, circular, narrow and profound.

Family PHILINID^E (Vol. xvi, p. 1). 

 Genus PHILINE Asc. (Vol. xvi, p. 2). 



The references to Colobocephalus and Colpodaspis should be 

 omitted from the generic and specific descriptions and references, as 

 it was deemed best to admit both as genera, pending definite infor- 

 mation on those forms. Add the following : 



P. TINCTA Verrill. 



Shell broad, oblong, rather large for the genus, widest in the 

 middle, very thin, tinged with smoky brown, not polished and with- 

 out distinct spiral lines, but with very distinct, fine, close, sinuous, 

 slightly raised, minutely wavy lines of growth. The apex is rounded 

 and shows neither spiral whorls, nor a depression. The outer lip 

 rises slightly above the body- whorl from which it is separated by a 

 broad and deep notch ; from the posterior shoulder to the anterior 

 end it is broadly flaring and convex, with a slight-rounded angle 

 about the middle; anteriorly it is a little narrower and evenly 

 rounded ; the columella margin is slightly excurved, with a thin 

 edge in front of the middle, and is reflected against the body-whorl, 

 where it joins it leaving a slight groove behind it, and winding into 

 the shell it forms a distinct, raised spiral fold, separated from the 

 more prominent inner surface of the body-whorl by a concave 

 groove. 



Length, 1075 ; breadth in middle, 8 ; breadth of aperture, 7 mill.
