SCALARIA. 81 



Section CIRSOTREMA, Morch, 1852. 



S. KIENERI, Canefri. PI. 17, figs. 21, 22, 26. 



Whorls about 15, well rounded, with a narrow shoulder above, 

 aculeately decussated by spiral ridges crossing thin longitudinal 

 lamellae. Length, 2'75 in. 



Mauritius, New Caledonia. 



S. cancellata, Humphreys, is a synonym. For the figure given by 

 Kiener for this species (fig. 26) Canefri has substituted the name S. 

 Kieneri, as he believes it to be different not only from Lamarck's 

 species (a Grignon fossil), but also from Sowerby's figure. To the 

 latter I cannot agree, for making due allowance for a worn speci- 

 men, and the general unnaturalness resulting from the method of 

 drawing Kiener's figures, they appear like enough. 



S. VARICOSA, Lam. PI. 17, figs. 23, 27. 



White, thick, cancellated by spiral and longitudinal lamellae, the 

 longitudinal sculpture more prominent, fimbriated, with occasional 

 strong tuberculated varices and a spiral basal rib ; whorls 12, with 

 very slight shoulder and deep suture. Length, 2 in. 



Philippines, Australia, Mauritius. 



S. attenuata, Helbling and S. fimbriata, Lam. are synonyms. 

 Var. ABBREVIATA, Sowb. Fig. 27. 



Shorter and thicker, the lamellae aculeate at the top of the 

 whorls, the margin crenated. Length, 1 in. 



Mauritius. 

 S. COCHLEA, Sowb. PL 17, figs. 24, 25. 



White, spirally striate, fimbriating the numerous rather thin, 

 sharp longitudinal lamellae, with occasional thick tubercular 

 lamellae ; whorls 8, with flattened shoulder and deep suture, basal 

 rib fimbriated. Length, 1'5 inch. 



Mediterranean Sea, Madeira, W. Coast of Africa, West Indies. 



Distinguished from the preceding species by its flattened shoulder 

 and general corkscrew-like appearance. The name of varicosa has 

 been applied to this species but the figure in the Encyc. Meth. cited 

 by Lamarck, although very poor, could never be mistaken for 

 coehlea. Brocchi, in 1814, described an Italian fossil under the 

 name of S. pumieea (fig. 25) which has been identified by several 

 good naturalists with the present species ; if this identification be 

 correct, Brocchi's name should have precedence, but I am not sat-
