ing carina ; subsequent four or five whorls broadly channeled, the 

 channeling being most apparent on the summit of the last whorl ; 

 spire with no trace of spiral striae, but sharply marked by arcuate 

 growth-lines; body whorl markedly convex below the shoulder 

 carina, giving the shell its characteristic fig-shaped form; the 

 sculpture of the last whorl consists of a varying number of spiral 

 ridges, strongest anteriorly, fading out more or less posteriorly; 

 some adult shells have the upper half of the body whorl nearly 

 or quite smooth, while in others it is striate to the shoulder; 

 aperture rather wide, posterior sinus deep. The relative pro- 

 portion of breadth to height varies as follows: 27X16, 28X18, 

 29X20, 35X23 mm. 



Our specimens are identical with some labelled by Gabb C. 

 cedo-nulli? But they are not the true C. cedo-nulli of Hwass.

Conus Kitteredgei, n. sp. 

 Plate 7, Figures 5, 6 



Shell with a short, acute, very concave spire, one-seventh 

 the length of the shell, which is less than twice the width; earli- 

 est two post-nuclear whorls faintly crenulate, the following three 

 slightly carinate; a channel appears on the penultimate volution 

 of the spire and on the last becomes well marked; spiral striae 

 absent, the spire being smooth except for arcuate growth-lines; 

 body whorl roundly angulated at the shoulder, the sides sloping 

 convexly to a rather broad base; upper two-fifths of the last 

 whorl typically nearly smooth, showing only faint, obsolete 

 spiral striations; lower three-fifths with well-spaced, narrow 

 ridges; aperture wide; outer lip sharp; posterior notch deep. 

 Length of shell 31, greatest width 17 mm* 



We have specimens with the ridges extending almost or 

 quite to the shoulder of the body whorl (fig. 6). These appear 

 to be a variety. They were found in the same zones as the typ- 

 ical shells.
