band ; sculptured all over with rows of minute, close-set, oblong 
punctures, more numerous and distinct towards the base, which 
is encircled by a number of narrow elevated ridges ; spire striate.

Described by Angas as C. Mvtcalfei,a name preoccupied by. 
Reeve. 
C. IntERRUPTUS, Brod. Pl. 27, fig.8; Pl. 19, figs. 100-2; Pl. 20, 
i figs. 83-5, 21. 
Shell long and narrow, with smooth elevated spire, body-whorl 
striate towards the base, the strize sometimes minutely granular; 
whitish, largely covered by longitudinal chocolate clouds, encir- 
cled by numerous lines of minute chestnut spots; spir2 nearly 
covered by chestnut or chocolate flammules. 
Length, 1°5—2°25 inches. 
West Coast of Central America to Mazatlan, Cape St. Lucas. 
Occasionally the entire body-whorl is covered with impressed 
or raised strizw, the latter smooth or granuiar. There are a 
number of synonyms, none of them differing much from the 
typical shells. These are C. mahogani, Reeve (figs. 1, 2), 
C. Ximenes, Gray (fig. 100), C. monilifer, Brod. (fig. 3), C. tor- 
natus, Brod. (fig. 4), C. Philippii, Kiener (fig. 5). 
C. arcuatus, Brod.and Sowb., although differing much in form, 
is still possibly an extreme variety of this species; and I am 
inclined to refer here also C. catenatus, Sowb. (fig. 21).

Chelyconus, Morch. 
C. caTus, Hwass. PI. 20, figs. 6-10. 
Shell bulbous, with convex, striate spire; body-whorl striate, 
the striz rounded, usually obsolete above, granular below, olive, 
chestnut-, chocolate- or pink-brown, variously marbled and 
flecked with white, often faintly white-banded below the middle. 
Length, 1°25-1°75 inches. 
Red Sea, Mauritius, Java, China, 
New Caledonia, Polynesia. 
C. eques, Brug. (fig. 10), is probably a synonym; the species 
is only known by the figure of which I give a copy.
