or closed; hight, about twelve lines; width, fifteen to eighteen lines. The base of the 

 body whorl is strongly convex; the band on approaching the aperture is situated above 

 the mid-hight, but receding therefrom it gradually gains a position on the outer edge of 

 the whorl; in the upper whorls it seems to be concealed in the suture. The upper side of 

 the body whorl, near the aperture, above the band, ascends with a gently convex or nearly 

 flat slope to the suture; approaching the apex the whorls become more convex. The band 

 appears to be rounded and about one line wide at the aperture. The aperture is some- 

 what effuse below. Surface with fine striae and some stronger ridges of growth near the 

 aperture.

We have here figured the type specimen which has about the 

 same degree of imperfection as our own examples. The shell is not 

 common.

Trochonema lescarboti nov. 



Plate 16, figure 5 



Shell moderately large, trochiform. Whorls broadly sulcate above, 

 gently convex peripherally and regularly convex below ; 3-4 in number. 

 Sutures impressed and bounded by an elevated ridge or carina within which 

 the surface is depressed in a broad and shallow sulcus bounded outwardly 

 by a sharp keel which lies at the shoulder of the whorl and from which the 

 whorl surface is abruptly depressed. No peripheral band is known though 

 the internal cast bears a peripheral depression. Lower surface not known 

 except from the cast, apparently regularly convex. Surface marked by 

 regular concentric Imes without revolving striae.

Original description. From three to four inches in length, apical angle about 20° ; 

 whorls apparently about ten, moderately convex ; a narrow band near the basal margin of 

 the whorl. Surface with very fine striae, which above the band curve backwards at an 

 angle of about 30° to the longitudinal axis of the shell ; below the band they curve for- 

 ward again to the suture. The band is one line wide on the last whorl of a specimen 

 three and one half inches in length. It is also once or twice its own width from 

 the suture. 



The locality of this species is given as the Gaspe sandstone, head of 

 falls of the Dartmouth river. This ascription of the formation is, we 

 are disposed to believe erroneous. Just beyond Ladysteps brook, a branch
