uniformly and moderately convex ; a narrow band in the middle. Sur- 

 face with fine striae which curve backwards to the band, forming therewith 

 an angle of about 40^. 



A specimen- consisting of the five last whorls and about half of the 

 aperture is thirty-three lines in length. Width of the last whorl, twelve 

 lines, and of the fifth whorl from the base, five lines. From the middle 

 of the body whorl to the middle of the fifth, the length is twenty-one lines. 

 The specimen therefore tapers seven lines in a length of twenty-one. 

 When perfect it probably had nine or ten whorls. 



Another specimen with six whorls is thirty lines in length ; width of 

 last whorl, twelve lines, and of the fifth, four and one-half lines. This 

 specimen retains the surface markings and band on a part of the body 

 whorl. The band is about one line in width.

MURCniSONIA EGREGIA. (N. sp.) 

 Plate 5, fig. 7. 



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 an^rle of about 30^ to the lonsitu 

 dinal axis of the shell ; below the band they curve forward again to the 

 suture. The band is one line wide on the last whorl of a snecimen three 



A, 



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

 the suture. 



The specimens are somewhat distorted by pressure, and the true form 

 of the whorls is somewhat uncertainly indicated. The following are the 

 characters of three specimens : 



1. — Length of the five last whorls, twenty-seven lines ; width of last 

 whorl, eleven lines ; width of the fifth whorl from the aperture, six lines. 

 The whorls are moderately and nearly uniformly convex, apparently moSt 

 elevated in the basal half. (PI. 5, fig. 7,) 



2. — This specimen is compressed; it consists of the seven last whorls, 

 and when perfect had about ten. The whorls are most prominent at the 

 band, above which they have a gently convex or nearly flat slope to the 

 suture. Length, thirty lines ; width of body whorl apparently about ten 

 lines, and of the seventh, about three lines. 



3. — Consisting of four whorls: length, nineteen lines; width of the
