Shuttleworth thus describes this species : — 



" Helix uvulifera. — T. rimato-perforata, superne planiuscula, subtus 

 inflata, striata,' cinereo-albida, solidula, nitidula; anfr. 5, lente accres- 

 centes, angusti, ultimus ad aperturam subito deflexus, subtns devius, 

 scrobiculato-constrictus ; apertura valde obliqua, auriformis, ringens, 

 valde coarctata ; perist. acutum, reflexo-patnlum, marginihiis plica lingui- 

 formi oblonga medio excavata profunde intrante junctis, dextro lamella 

 profunde immersa in apicula filiformi reflexa desinente, basali tuberculo 

 'dentiformi obliquo et sinuoso instructo. 



"Diam. maj. 12, min, 11, Alt. 7 mill. 



" Hah. — In insulis parvis ' Long Keys' sinu dicto ' Sarazota,' Florida 

 Austr. (Rugel). 



" Ohs. — Specimina numerosissima examinavi. Proximo H. auricu- 

 latae affinis, sed textura, colore, ac apertura minus coarctata, peristo- 

 mateque minus producto satis distincta. H. Ariadna? Pfr. in Chemn., 

 ed. 2, tab. 65, f. 29-31, etiam affinis, at differt fignra testa tantum 

 rimata sine vestigio perforationis. Nomen specificum ah apicula lamella 

 marginis dextri peristomatis, Uvulae Humanse baud dissimili, assumptum. 

 :Sed character bio in omnibus speciebus afiinibus plus minusve obvius est." 



The annexed figure III. of the aperture o*f H. uvulifera 

 Fig III Shuttl., twice the natural size, is from a specimen 

 received direct from the author of the species. 



H. uvulifera may be distinguished from H. auri- 

 culata by the character of the labrum, which is 

 equally produced from the superior angle of the 

 Iff. xmM/era Shuttl. parietal proccss, to the base of the inferior tooth
