The unique type of this species, which is in the collection of 
the Dominion Geological Survey, was dredged by Mr. Spread- 
borough at Skidegate. It has six post-nuclear whorls and 
measures; length 5-2 mm., diameter 2*8 mm. 
Odostomia (Evalea) sxidegatensis, new species. 
Plate X, fig. 1. 
Shell elongate-conic, yellowish white. Nuclear whorls com- 
pletely immersed in the first of the succeeding turns, above 
which only half of the last turn projects. Post-nuclear whorls 
very slightly rounded, feebly shouldered at the summit, marked 
by incised spiral lipes, which are much stronger on the first 
two volutions than on the remaining. Of these lines, ten ap- 
pear upon the second turn. On the last, they are reduced to 
exceedingly fine striations. Sutures moderately constricted. 
Periphery of the last whorl decidedly inflated and feebly angu- 
lated. Base somewhat prolonged, moderately rounded, marked 
by fine, closely spaced, spiral striations. Aperture large, oval; 
posterior angle acute; outer lip thin; inner lip strong, moder- 
ately curved, and partly reflected over and appressed to the 
base, provided with a strong fold at its insertion. 
Seven specimens of this species were dredged at Skidegate: 
three at Sta. 5. which may be considered eotypes; two at Sta. 4, 
and two at Sta. 1. Of these, two of the cotypes are in the 
Dominion Geological Survey, and one in the U. S. N. M., Cat. 
No. 220116; of the other two lots, one from each station is in 
the collection of the Dominion Geological Survey and the 
U. S. N. M.: the cotype figured has five post-nuclear whorls 
and measures: length 3*4 mm., diameter 1*6 mm.
