gers College, but is of still larger size and so characteristic in sOilie of its 

 features in which it differs from that one that I have concluded to notice it 

 under a separate head, hoping that other specimens may be found to verify 

 it. The fragment consists of the principal volution and a portion of the 

 next above, the anterior beak having been broken near its upper part. The 

 volutions are somewhat rounder than are those of F. Hector, the angu- 

 lations being less distinct and the vertical folds more subdued. Both of 

 these features, however, might result, at least in part, from the excessive 

 flattening of the cast. The spiral lines, however, although the normal 

 number possessed by the typical form are present and retain very nearly 

 their relative position, are continued over the entire surface, both above and 

 below the angulation of the whorl, with two intermediate finer ones between 

 each of the principal lines ; the finer lines are also continued below and 

 upon the anterior beak as far as that portion is preserved. In the prelimi- 

 nary examination of the species I had grouped this with the specimens of F. 

 {N.) Hector, considering it only as a crushed specimen of that species pre- 

 serving the markings in^a more perfect condition. But on separating the 

 largest individual of that one from the matrix, I find the fine transverse 

 lines of growth perfectly preserved, without a vestige of spiral lines on the 

 upper surface of the volutions, convincing me that this can scarcely be the 

 same species. I therefore indicate it as above. The locality and geological 

 position is the same as in that case. 



Fusus (Ueosalpinx ?) multicostatus, n. sp, 

 Plate XXIV, Figs. 6, 7. 



Shell small, elongate-oval, or short-fusiform in general outline, spire 

 forming one-half of the entire length, the body whorl large and termi- 

 nating in a short beak. Volutions extremely ventricose, almost inflated, 

 with deeply marked suture lines between them. Apical angle about 45°. 

 Aperttire large, broadly ovate and terminating below in a short, narrow 

 canal. Volutions crossed by closely arranged, rounded, vertical folds, 

 which are confined to the upper two-thirds of their surface, becoming 

 obsolete a little below the largest part, and are separated by narrow con- 

 cave interspaces; twelve to fourteen of the folds may be counted on each
