 Length 5.8 mm.; diameter 2.4 mm. It bears the two localities Puget 

 Sound and Santa Barbara, ^ind probably comes from Puget Sound. 



Three other specimens (Cat. No. 126660, U.S.N.M.) were collected

TURBONILLA (PYRGOLAMPROS) NEWCOMBEI, new species. 

 Plate XLV, fig. 6. 



Shell regular!}", broadly conic, white on the posterior half and light 

 brown on the anterior half of the exposed portion of the whorl; base 

 white. Nuclear whorls decollated in all the specimens seen. Post- 

 nuclear whorls somewhat overhanging, decidedly contracted toward 

 the periphery from the anterior fifth of the exposed part; almost 

 flattened posterior to this, and closely appressed at the summit, sepa- 

 rated by strongly marked sutures. Ribs about 18 upon all the turns, 

 almost vertical, moderately elevated, rounded in the middle, decidedl}' 

 flattened and widened at the summit, disappearing at the periphery. 

 Intercostal spaces not depressed below the general surface, a little 

 wider than the ribs. Periphery and the moderately long base well 

 rounded, smooth, excepting the fine spiral striation which covers the 

 entire surface of the shell. Aperture subquadrate, posterior angle 

 acute; outer lip thin, showing the color bands within; columella 

 slender, oblique and slightly revolute. 



The type (Cat. No. 126660, U.S.N.M.) was collected by Dr. C. F. 

 Newcoml)e, at Victoria, Vancouver Island, British Columbia. It has 7 

 post-nuclear whorls which measure: Length 5.4 mm., diameter 2.1 mm. 

 Eighteen additional specimens were collected by Rev. G. W. Taylor

 the other 6 form Cat. No. 196214, U.S.N.M. 



TURBONILLA (PYRGOLAMPROS) OREGONENSIS, new species. 

 Plate XLV, fig. 2. 



Shell elongate-conic, wax-yellow, with two yellowish-brown spiral 

 bands, the posterior one of which encircles the turns a little above the 

 periphery, wdiile the anterior one, which is a little wider, is imme- 

 diately posterior to it, the two ])eing separated by a space about as 

 wide as the posterior band. Nuclear whorls decollated in all our 

 specimens. Post-nuclear turns very slightly rounded, moderately 

 contracted at the periphery and closely appressed to the preceding turn
