impressed, of irregular width. Sutures well impressed. Periphery 

 of the last turn somewhat inflated, well rounded. Base short, well 

 rounded. Entire surface of spire and base crossed by numerous very 

 fine, closely spaced, spiral striations. Aperture broadly oval; pos- 

 terior angle acute; outer lip thin, showing the external markings 

 within by transmitted light; inner lip moderately strong, slightly 

 curved and revolute. 



The unique type was dredged in Barkley Sound, Vancouver Island, 

 British Columbia. It has 8 post-nuclear whorls (having lost the 

 nucleus, and probably the first IJ post-nuclear turns), and measures: 

 Length, 6 mm.; diameter, 1.6 mm. 



This species follows Turhonilla (Pyrgolampros) halistrepta in the 

 key.

Turhonilla {Pyrgolampros) rinella Dall and Bartsch, Dep. Mines, Geol. Surv., 

 Canada, 1910, pp. 14-15, pi. 1, fig. 2. 



Shell, elongate-conic, reddish wax-yellow, a httle lighter on the 

 posterior half between the sutures; anterior half of base almost white. 

 Nuclear whorls decollated. Posterior two-thirds of the post-nuclear 

 whorls between the sutures flattened; anterior third rounding moder- 

 ately toward the periphery; whorls marked by feebly developed, 

 low, broad, retractive, axial ribs, which are separated by narrow, 

 shallow, intercostal spaces. Of these ribs, 22 occur upon the fourth, 

 24 upon the fifth and sixth, 26 upon the seventh, and about 42 upon 

 the last of the remaining turns. Upon the last they are very irregular 

 and even less strongly developed than on the preceding. Suture well 

 impressed. Periphery of the last whorl somewhat inflated, well 

 rounded, with scarcely any traces of axial sculpture. Entire surface 

 of spire and base marked with numerous wavy, closely spaced, spiral 

 striations. Aperture broadly oval; posterior angle acute; outer lip 

 thin; inner lip obUque, slender, and revolute; parietal wall covered 

 with a fairly thick callus. 



The unique type was collected in Barkley Sound, Vancouver 

 Island, British Columbia, and is in the collection of the Geological 

 Survey, Ottawa. It has 9 whorls remaining, which measure : Length, 

 8.5 mm.; diameter, 2.3 mm. 



This species foUows Turhonilla (Pyrgolampros) pesa in the key. 



TURBONILLA (PYRGISCUS) GRIPPI, new species. 

 Plate 36, fig. 9. 



Shell very elongate-conic, light chocolate brown. (Nuclear whorls 

 decollated.) Post-nuclear whorls well rounded, slightly shouldered 

 about one-third of the distance between the sutures, anterior to the 

 summit, marked by rather strong, decidedly retractive, axial ribs, of
