which the first two nuclear are smooth,, the five following show a 

 coronation under the lens, while the remainder have only a spiral 

 ornamentation. Spiral sculpture of three or four strong threads 

 on each volution of the spire. The spirals are absent on the last 

 whorl below the shoulder, but are strongly developed near the 

 base of the shell. Lines of growth inconspicuous. Length of 

 shell 50 ; greatest width 26 mm.

Pleurotoma boadiceoidcs n. s. 

 PI. I, figure 7. 



This species is a miniature of P. boadicea, Dall, for with an 

 equal number of whorls it is but half the size of the specimen 

 figured by Dr. Dall. Whorls eight, of which the first two are 

 smooth, the third strongly carinated and the remainder orna- 

 mented with riblets and spirals. Spiral sculpture of equal 

 threads that can easily be seen without a lens ; eighteen or 

 twenty are present on the last whorl, and two or three on the 

 preceding whorls. Longitudinal sculpture of nodular riblets 

 (seven on the last whorl) occurring immediately below the sub- 

 sutural grooves. Aperture narrowly elliptical ; notch broad, not 

 deep ; outer lip simple, Length of shell 7 ; greatest width 

 2.5 mm. 



It is possible that this may prove to be a small variety of 

 boadicea when more specimens are found.

 Pleurotoma Kempi n. s. 

 PI. I, fig. 8. 



Shell small, short fusiform, whorls seven, of which the first 

 three are smooth, the remainder sculptured ; suture distinct, 

 waved ; spiral sculpture of fine, sub-equal threads visible without 

 a lens, present on the body-whorl below the groove, absent (or 

 worn) from^he spire. Longitudinal sculpture of nodular riblets 

 (eight on the last whorl) developed just beneath the grooved
