Habitat uni 



Aetceon oblongus MKE., Mai. Bl. i, p. 27. 



Most nearly allied to A. punctatus (Tornatella p., Fer., Tabl. 

 p. 108, no. 5), but differing in being slenderer, with more point 

 spire, fine transverse striation, and in the peculiar coloration 

 crowded pale brick-red punctate dice-spots. The last whorl has li 

 unequally spaced grooves, of which the third, fourth and fifth boun< 

 the widest intervals ; the lower grooves are closest. The penultii 

 ate whorl has three grooves. The colurnellar fold is the same 

 the two species. 



S. NITIDULA Lamarck. PI. 20A, fig. 57. 



Shell solid, oval, with very short spire, mamillar apex and obes 

 body-whorl ; shining, polished, light flesh-pink. Surface smoot 

 except for a few spiral grooves at the base. Whorls about 

 Aperture narrow, three-fourths the entire length of the shell, tl 

 outer lip very thick within, bevelled to a sharp edge; columell 

 bearing a very large massive spiral fold, with a small fold of calh 

 above it on the parietal wall. Alt. 17, diam. 10 mill.

This polished, compact species is distinguished by the smoothn< 

 and delicate flesh color of its polished surface, and the massive, pi 

 jectingcolumellar fold. It seems to be widely distributed in Ind< 

 Pacific waters.
