Guppy,' from Triniclatl, said to be synonymous -with this species, is 

 probably distinct.

Testa minuta, umbilicata, depressa, orbiculata, pellucida, lincis 

 incremeuti tenuissimis striata ; spii'a brevis, ad apicera obtusa ; 

 anfraetus quatuor, convexi, lento accrescentes, sutura profunda sc- 

 juncti, ultimus ad peripheriam rotuudatus; apertura parva, oblique 

 lunata ; peristoma tenue, margine columellari ad insertionem vix 

 expanse vel reflexo. Diam. niaj. 1*6, min. 1*5 mm. ; alt. 1mm. 



Hab. — St. Vincent (H. H. S.). One dead specimen. 



A single live example of this minute species was also obtained by 

 Mr. Smith at Grenada. 



6. YiTEEA (CoNULTjs) siMULAXS (C. B. Adams). 



Helix simulans, C. B. Adams. — Contrib. Conch., vol. i, p. 35; PfeifFer, 

 Mon. Hel., vol. iii, p. 51 ; Conch.-Cab., ed. 2, p. 320, 

 pi. cxxix, figs. 13-15; Reeve, Conch. Icon., sp. 351. 



Zonites {Co7iuIus) simulans. — Tryon, Man. Conch., ser. II, vol. ii, p. 174, 

 pi. liii, figs. 49, 50. 

 iZai. —Jamaica (Adams); "open allmdal land near the sea; rare 



under stones" (H. H. S.). 



The specimens from St. Vincent agree precisely with this -Jamaican 



species. " Helix Gictidlachi,^' Pfr., is probably the same as this species. 



It occurs in Cuba, Jamaica, St. Thomas, Nicaragua, etc. 



7. Thysanophoea fuscula (C. B. Adams). 



Helix fuscula, C. B. Adams. — Contrib. Conch., vol. i, p. 35; Pfeiffer, 

 Mon. Hel., vol. iii, p. 82 ; Conch.-Cab., ed. 2, p. 357, 

 pi. cxxxvi, figs. 21-23; Tryon, Man, Conch., ser. II, 

 vol. iii, p. 98, pi. xix, fig. 24. 



Thysanoiyliora fmcula. — Pilsbry, Man. Conch., ser. II, vol, ix, p. 58. 

 hah. — Jamaica (C. B. Adams); "Leeward, dry forest, above 



Chateaubelair, 1000 feet, in rubbish, crevices of rocks, very rare" 



(H. H. S.). 



It is possible that this species and Vitrea simulans may have been 



introduced into St. Vincent with vegetation. One specimen was also 



found by Mr. Smith at Grenada.

Ifab. — It abounds in rainy weather in the underwood about Fort 

 Charlotte and other parts of the island (Guilding) ; " common locally, 

 principally on the leeward side, in rather damp forest hillsides, below 

 1,500 feet. In damp weather is found on leaves or tree-trunks; 

 conceals itself at roots of trees in dry weather " (H. H. Smith),
