144 SOLIDULA. 



S. OBLONGA Menke. 



Shell elliptical-oblong, cylindrical, rather solid, shining, trans- 

 versely silicate and very delicately striated, longitudinally obsoletely 

 striated. Spire conical, acute. Whorls 6, slightly convex. Aper- 

 ture narrow ; columella biplicate, the lower fold large, bilobed, the 

 lower lobe smaller ; whitish pallidly tesselated with square punctate 

 spots. Alt. 7.7, diam. 3 lines. (Mke.~) 



Habitat unknown. 



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



Most nearly allied to A. punctatus (Tornatella p., Fer., Tabl. 2, 

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

 spire, fine transverse striation, and in the peculiar coloration of 

 crowded pale brick-red punctate dice-spots. The last whorl has 15 

 unequally spaced grooves, of which the third, fourth and fifth bound 

 the widest intervals ; the lower grooves are closest. The penultim- 

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

 the two species. 



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



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

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

 except for a few spiral grooves at the base. Whorls about 7. 

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

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

 bearing a very large massive spiral fold^with a small fold of callus 

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

This polished, compact species is distinguished by the smoothness 

 and delicate flesh color of its polished surface, and the massive, pro- 

 jecting columellar fold. It seems to be widely distributed in Indo- 

 Pacific waters.
