50 THE NAUTILUS. 



with slightly oblique stripes of red-brown, ochre, blue aiul white, the 

 base red with white radial streaks ; when whorls above the last four 

 are retained they are scarlet with some white streaks. 



The surface is glossy, with traces of fine, nearly effaced growth- 

 striae, and under close inspection some widely spaced lines may be 

 seen, indicating periodicity in growth. Spiral sculpture consists of 

 fine, distinct but low spiral threads, larger ones at intervals : 4, 5, or 

 6 smaller striae between the larger ; around the umbilicus the striae 

 are coarser, alternately larger, and latticed by tlie growth-striae. 

 Above the penultimate whorl the spirals are subequal. The spire is 

 straightly conic, with 4 whorls below the tongue-shaped apical sep- 

 tum ; but an empty whorl or more persists above the septum. The 

 whorls are strongly convex, separated by a smooth, simple and deep 

 suture, which close to the aperture descends a little more rapidly, the 

 last whorl becoming free there for a short distance. The aperture is 

 vertical, slightly longer than wide ; the outer side more convex than 

 the inner; reddish-brown inside. Peristome thin, the inner half 

 nearly white, outer half brown-tinted ; broadly reflexed throughout, 

 a little retracted above and below, slightly produced in a short lobe 

 above. Operculum unknown. 



Length 25, diam. 15.5 mm.; aperture with perist. 12 mm. long.; 

 4 whorls remaining. 



Length 27, diam. 15 mm.; aperture with perist. 12 mm. long., 5 

 wliorls remaining.

This magnificent species is related to C hamlini var. major Crosse 

 (Jour, de Conchyl., 1890, p. 300, pi. v, f. 6 a, b). but that is a far 

 smaller shell, length about 17 mm., with chestnut-brown streaks ex- 

 tending upon the base. The figure in black and white gives a poor 

 idea of the beautiful coloring of this shell, which is named in honor 

 of my friend, John B. Henderson, Jr.

The shell is depressed, very solid, the last whorl cream-white, 

 gradually changing on the penultimate to sulphur-yellow, the color
