The genus Pineria was established bj Poey in 1854 {Me- 

 morias, I., 428), and thns cliaracterized : — 



T. bulimiformis, imperforata, turrita, apertura rotundata, peris- 

 toma simplex, rectum, imdique acutum. Animal nudipes tentaculis 

 duobus retractilibvis iustructura, apice oculatis ; labrum rotundatum ; 

 reptatio sinuosa. 



Poey described two species, P. terebra and Beathiana, both 

 from the Isle of Pines, of which figures are given {Metnorias, 

 I. c, tab. 34, f. 12-18). 



He remarks that he had examined the living animal of P. 

 Beathiana with great care, but could detect no trace of " in- 

 ferior tentacles," and Dr. Gundlach had satisfied himself of 

 their absence in P. terebra. Observing that the form of siiell 

 (columella excepted) and sculpture of the former species was 

 somewhat like that of Macroceramus turricula, Pfr., Poey 

 studied its soft parts and found such tentacles existing. 



In 1856 Pfeitfer {Malak. Bl. III. p. 46) described Bxilimus 

 Vieque7isis, from Vieque, and suggested its alliance with 

 Pineria. The species is figured in Notit. Conch. Fasc. xxxi. t. 

 93, f. 39-41. 



The late Pev. II. Parkinson, in 1857, discovered P. Yiequen- 

 sis in Barbados. 



In 1858 Fischer {Journ. Conch, vii. 184, t. 7,f. 7-8) described 

 Helix Schrammi, from Guadaloupe. 



Pfeiffer (Mon. vi. 343) adopts the genus Pineria, for B. 

 Viequensls, H. Schranimi., and Poey''s two species, and re- 

 marking on the evident affinity of Fischer's species with Vie-
