Pfeiffer thought this might be an immature shell. The 

 figures certainly have the appearance of a young Eucalodium 

 or Coelocentrum. It is obviously not an Obeliscus. 



17. 0. PEREGRINUS Pfeiffer. Unfigured. 



Shell perforate, subfusiforin-turrited, rather solid, striat- 

 ulate, waxen. Spire eonvex4urrited, the apex rather obtuse, 

 suture subcrenulate. Whorls 8%, a trifle convex, the last 

 subequal to one-third the length, sulbcompressed at base. 



Aperture oblique, oblong, 'angular ait both ends ; peristome 

 simple, unexpanded, the margins 'Converging, right margin 

 arcuate, <eolumellar margin nearly straight, dilated to the 

 base of the aperture, flat, wide. Alt. 18, diam. 5% mill.; 

 aperture, alt. scarcely 6, width 3 mill. (Pfr., from type in 

 Cuming coll.) . Habitat unknown.

An unfigured form, the systematic position of which can 

 only be ascertained by >an examination of the type. 



Antillean Obeliscus (Subgenus STENOGYRA Shuttlw.). 

 With the possible exception of 0. salleanus and rangianus, 

 the following Antillean Obelisks 1 belong to the subgenus 

 Stenogyra, the type being 0. terebraster (Lam.). The em- 

 bryonic shell is oblong, with an obliquely truncate columella 

 (pi. 37, fig. 103, terebraster from Loisa, Porto Eico). The 

 adult has a more or less developed callus on the columella, 

 such as we do not find in Protobeliscus. The group extends 

 over eastern Cuba, Haiti and Porto Riico, but is wanting in 

 Jamaica and western Cuba. The Cuban species are closely 

 related and difficult to distinguish.
