14. Oleacina (Laevoleacina) oleacea straminea (Deshayes). 



Achatina slraminea Deshayes, in Ferussac, Hist. Nat. Moll. Terr. & Fluv., Vol. 

 II, 1851, p. 172, PI. 123, figs. 11-12. — Oleacina oleacea straminea Pfeiffer', 

 Nov. Conch., p. 318, PI. 77, figs. 3-4; Pilsbry, Manual of Conchology, Vol. 

 XIX, 1907, p. 138, PI. 33. figs. 5. 9- 



Habitat. — Casas Mountains; probably also Caballos Mountains and 

 Punta del Colombo. 



Not distinguishable from forms found about Havana and Matanzas. 

 One specimen taken by Dr. Nicholas (exact locality not given) 

 measures only 19 mm. by 8 mm., though fully adult. It is of very 

 dark color. 



15. Oleacina (Laevoleacina) solidula (Pfeiffer). 



Polyphe?nus solidulus Pfeiffer, Wiegm. Archiv, Vol. I, 1840, p. 252. — Oleacina 

 solidula Pilsbry, Manual of Conchology, Vol. XIX, 1907, p. 140, PI. 33, figs. 

 3-4- 



Habitat. — Casas and Caballos Mountains; Punta del Colombo. 



Taking the form found about Matanzas as the true species, none of 

 those from the Isle of Pines are wholly typical. 



16. Oleacina (Laevoleacina) follicularis (Morelet). 



Glandina follicularis Morelet, Test. Nov. Ins. Cub., 1849, p. 14. 



Habitat. — Casas Mountains. 



The extremes of this and the preceding species ai^e readily dis- 

 tinguishable, but a number of intermediates connect, so that it is 

 difficult to determine where one begins and the other ends. Typical 

 O.follictdaris has a shorter antepenult whorl, a less sharply descending 

 last whorl, a narrower and longer aperture and the columella is 

 straighter. Specimens from the Caballos Mountains and Punta del 

 Colombo generally belong to the intermediate forms. Morelet's type 

 evidently came from the Casas Mountains. 



17. Oleacina (Laevoleacina) subulata (Pfeiffer). 

 Polyphemus subulalus Pfeiffer, Wiegm. Archiv, Vol. I, 1839, p. 352. 

 Habitat. — Casas and Caballos Mountains; Punta del Colombo. 

 The inadequate Latin descriptions applied to these small Cuban 



Oleacinas by their authors has made critical identification extremely 

 difficult. Assuming Matanzas to be the type-locality, the shells 

 from the Isle of Pines certainly belong to this species.
