SCALARIA. 79 



S. SUTURALIS, Hinds. PI. 16, fig. 8. 



Narrow, whitish, stained with brown, minutely spirally striated ; 

 whorls 9-10, convex, contiguous, rather compressed, keeled and 

 grooved at the suture, with very infrequent rounded varices. 



Length, 9 mill. 



Malacca. 

 S. GENICULATA, Brocchi. PL 16, fig. 17. 



Reddish brown, whorls 8, well rounded, with fine, close, longitu- 

 dinal lamellae and occasional thick varices. Length, 1 in. 



Atlantic and Mediterranean Europe. 



First described as a pliocene fossil. Recent specimens are occa- 

 sionally dredged at considerable depths. 



S. TURRICULA, Sowb. PI. 16, figs. 13, 4, 6. 



Covered perforate, rather thin, turreted, white, often with two 

 faint chestnut bands, with very close fine spiral line; whorls 8-9, 

 with 12-13 lamellae, some of which are varicose. Length, 18 mill. 



West Indies. 



S. turrita, Nyst is a synonym; S. nuda, Sowb. (figs. 4, 6), 

 described without locality, appears to be another. 



S. LINEATA, Say. PI. 16, figs. 14, 9. 



Shell thick, shining, porcellanous, with traces of fine lamellae, 

 with wider interspaces, and occasional varices ; whorls 6-7, moder- 

 ately convex, white or yellowish or brownish white with two narrow 

 chestnut bands, the lower one the most conspicuous. 



Length, 12-15 mill. 



Southern Atlantic Coast of the United States. 



Reeve's figure represents a specimen in which the lamellae are 

 unusually developed, whilst the normal denuded state is 

 described as a new species, S. unicostata, Sower by (fig. 9), and 

 changed by Canefri to S. Fischeriana on account of S. uncinaticosta, 

 d'Orb, mistaken by him for unicostata. 



S. ERRONEA, Canefri. PL 16, fig. 7. 



Attenuated, smooth, whitish, with fulvous apex, whorls 8, convex, 

 with rare varices. Length, 18 mill. 



? Port Jackson, Australia. 



Wrongly figured by Sowerby for S. Morchi, Angas, which is a 

 very different species.
