Terrestrial Mollusca from Trinidad. 441 



diminuta and H. perspectiva ; but it is much more conical 

 than those species or any of their allies that I am acquainted 

 with, having in this respect more of the shape of H. lahy- 

 riiithica^ Saj. 



8. Bulimulus tenuissiniuSj F6v. 



A species not hitherto distinguished by me from B. /rater- 

 cuius. If the Trinidad form now recorded is really B. tenms- 

 simusj it differs from Antillian examples in having a narrower 

 mouth. 



9, Pupa uvulifera^ n. sp. 

 Testa umbilicata, cylindrica, paiilum ovata, leviter striatiila, corneo- 



brunnea, parum nitens ; anfr. 5-6, convex! ; apertura semi- 



ovata, plieis munita, plica parietalis verticalis, lamelliformis ; 



margo extenius incrassatus, refiexus, margo cohimellaris late 



reflexus ; umbilicus apertus, baud profundus. 

 Long. 3 millim,, lat. 1. 



Allied, probably, to P. Jamaicensis. It is of somewhat stouter 

 figure than that species. 



10. Pujya aurijormis, n. sp. 



Testa subperforata, ovata, brunnea, subpellucida, leviter striata, vix 

 nitens ; anfr. 4|-5, convexi, ultimus dimidiam longitudinem su- 

 perans ; spira brevis, convexa, apex obtusus ; apertura semi- 

 ovalis, auriformis, plica parietali munita ; peristoma incrassatum, 

 reflexum, margine externo valde sinuato, margine columellari late 

 reflexo. 



Long. 2 millim., lat, 1|. 



Distinguished from the last by its shorter and more ovate 



figure. 



11. Helicina ignicoma^ n. sp. 



Testa orbiculato-conoidalis, radiatim sinuato eostellata, tenuis, sub- 

 diapbana, nitens, subrufa ; spira brevis, conoidalis ; apertura 

 oblique semiovata ; columella brevissima, simplex ; peristoma 

 anguste expansum et reflexum, margine basali parum sinuato ; 

 callus basalis tenuis, albidus. 



Alt. 3 millim., lat. maj. 4|, lat. min. 4. 



Operculum tenue, diaphauum. 



An orbiculate conoidal Helicina^ sculptured with numerous 

 fine, oblique, somewhat sinuate riblets ; with five whorls, the 

 last somewhat carinate ; aperture oblique, semiovate ; peri- 

 stome narrowly expanded and reflected ; basal margin slightly 

 sinuate. 



Very closely allied to li. rvgosa^ Pf. (Cuba), and scarcely 

 less so to H. pUcatida (Martinique, Dominica, &c.). One 

 character gives a ready distinction : in the two species men-
