PLATE XLII, FIGURE 20, a, 6. 
A specimen, which I refer to S. a@ffinés, smaller and more slender 
than the preceding species, was dredged by us, in 1877, in Bedford 
Basin, near Halifax, Nova Scotia, 35 fathoms, soft mud. 
It is a smooth, glossy, translucent shell, slightly curved, with a 
round aperture. The posterior aperture has only one slight notch. 
Length, 6""; diameter, 1™™".

A few specimens, agreeing well with the figures and description of 
this species, were taken at station 871, in 115 fathoms, 891, in 500 
fathoms, and 947, in 812 fathoms.

PLATE LVIII, Figures 30, 30a. 
This large and highly polished species occurred at many of the 
stations, but most abundantly at 869 to 871 and 8738 to 877, in 85 to 
192 fathoms, and 949 in 100 fathoms. Other stations are 891, 894, 
895, 898, 943, 945, 947, 949, 994, 997-999, 1028, 1038, in 100 to 500 
fathoms.

PLATE LVIII, FIGURES 31, 32. 
This species, like others of the genus, varies considerably in form 
and proportions. I have figured two forms from camera-drawings. 
This occurred in considerable numbers, living, at station 871, in 
115 fathoms; it was also taken at.station 873, in 100 fathoms 
and at 949, 100 fathoms, 1881. It is a small, polished species 
rather stouter and more swollen than the next,
