are two or three low cords in each space, all being slightly irregular. 

 The rather prominent siphonal fasciole is apricot-orange colored. 



The aperture is white , outer hp having a series of five or six teeth 

 within, the upper and lower ones sHghtly larger. The columella 

 is straight, having several short, rather strong transverse folds be- 

 low the middle. 



Length 22.5, diameter 14 mm. 



It is related to S. concatenatum (Lam.), but it is a more compact 

 shell with smaller white aperture, and much less coarse sculpture. 



Cymatium species. 



Cymatium intermedium (Pease) is the most abundant Triton in 

 Oahu. C. chlorostoma (Lam.) is found in Honolulu Harbor, Hilo 

 and other places. C. tuberosum. Lam. is not uncommon on reefs. 



C. vestitum Hinds^ is represented by a race in which the tooth 

 intervals are carnehan red or rufous, the form more slender, and the 

 few intervariceal ribs are very weak. Length 74, diameter 34mm. 

 This race may be called C. vestitum msulare. Type no. 35279 A.

The finest specimen I have seen is in the collection of L-win Spald- 

 ing.

The shell is somewhat pear-shaped, rather solid, white in the only 

 examples known, which are long-dead shells. 



The rather short spire is concavely conic. In the most perfect 

 example the penult whorl is weakly angular above the suture, with 

 very weak, coarse nodes; the next earlier whorl is distinctly angular 

 and tuberculate; above this the tubercles become closer, longer, 

 so that the next two whorls are costate. The conic summit, of about 

 3 convex whorls, is smooth. The last whorl is very slightly com- 

 pressed between face and back. It is slightly swollen behind the 

 outer lip, somewhat flattened preceding the swelling, on the ventral 

 face strongly convex above. It is smooth except for oblique grooves 

 around the lower part and more or less distinct spiral threads near 

 the lip. The suture descends in the last third of a whorl, ascending 

 a little at its termination. The aperture is narrow. Outer lip not 

 excavated posteriorly, having a moderate sinus anteriorly; closely 

 lirate within. The inner lip is thick, with well defined edge, and 

 is regularly lirate throughout.
