Species varietatibus certis Phys heterostrophe similis, sed habitu 
graciliore, anfractibus minus convexis, colore fusco-corneo et labro 
tenui satis diversa est. 
2. PLANORBIS REFULGENS, Dkr. P. testa solidiuscula, nitidis-

Species pulcherrimarum una sui generis. Anfractus fere sex 
rotundati, supra fusco-cornei, infra pallidiores, striis tenuissimis incre- 
menti instructi sunt ; sub microscopio anfractus priores strias spirales 
minutissimas ostendunt. Spira embryonalis in latere superiore, ut 
solet, infundibuliformis. Margo aperturalis superior acutissimus, 
parum productus. Hee species habitu Planorbi Guadaloupensi, Sow. 
haud dissimilis est.
