the specimen figured by Benoit. The parietal lamella is de- 

 veloped only in fully adult shells, is sometimes very small, 

 and in some apparently adult shells is wanting. The palatal 

 region shows a more or less conspicuous ridge corresponding 

 to the external furrow. Very often a small white fold stands 

 upon this ridge, though not in all adult shells ; and the type 

 of Benoit was without it. Specimens of full size and in the 

 same lot may therefore be found with one, two or three teeth. 



Length 5.5, diam. 2 mm. ; 6^ whorls. 



Length 4.5, diam. 2.1 mm. ; 5% whorls. 



P. gibUfunnensis, which I have net seen, does not appear to 

 differ from the more fully toothed examples of scalaris, yet it 

 may be a distinguishable race. Sowerby's Pupa scalarina, 

 which he got tangled up with a Cuban Cerion, is the triden- 

 tate form of scalaris. Westerlund's diagnosis of occulta (Nbl. 

 d. in. Gcs., 1892, 193) reads a good deal like scalaris. 



Var. (?) gibilfunnensis (De Greg.). --"A small, elegant, 

 very characteristic species. It is of an earthy color, orna- 

 mented with marked, laminar, oblique riblets. That which 

 characterizes and distinguishes it from other related forms is : 

 (1) the shape of the whorls, which are (especially the penult) 

 extremely convex in the middle, constricted anteriorly and 

 posteriorly, in such manner that they are carinate. (2) The 

 arrangement of teeth in the aperture, of which there are two 

 rather large on the columellar side, one rather slender on the 

 outer lip. This last tooth is much less conspicuous, situated 

 within, and sometimes transformed into a fold, or a slight 

 protuberance ; it corresponds to a concavity of the outer side 

 of the whorl, which is continued spirally to the outer lip, in 

 which it frequently produces a sinuosity. 



"This species is related to scalaris Ben. (111. Sist., pi. 5, f. 

 37; Nuovo Cat., p. 96) and also philippii Cantr. (Ben., 111. 

 Sist., pi. 5, f. 38), but is quite distinct from both by the shape 

 of the whorls and by the tooth of the outer lip" (Pupa gibil- 

 finmensis De Gregorio, II Naturalista Siciliano, xiv, Sept. 

 1895, p. 204).

17. GRANOPUPA REFUGA (West.). 



Very similar to Pupa rupestris Phil., but the shell is more 

 slender, more distantly and more strongly ribbed, the riblets
