1932. Cochlostyla (Cochlodryas) florida florida Bartsch, Journ. Washington Acad. 

 Sci., vol. 22, p. 336. 



Shell ovate, the last turn with a bright grass-green periostracum, 

 which gradually grows paler posteriorly and eventually passes into the 

 flesh-colored apex. In typically colored specimens there is a narrow 

 white thread at the summit followed by a brown band immediately 

 adjacent to this. There is also a brown spiral band of about equal width 

 at the periphery and another between the two. The columellar area 

 is surrounded by a bright chestnut-brown patch. The interior of the 

 aperture and peristome are white. The nucleus consists of 1.8 turns, 

 which are smooth, barring incremental lines and indications of fine 

 spiral striations on the last turn. The nuclear turns and the first 

 postnuclear turns form a blunt apex. The postnuclear whorls are 

 somewhat inflated, strongly rounded, appressed at the summit, and 

 marked by feebly retractively curved lines of growth and very fine 

 spiral striations on both spire and base. The periphery of the last 

 turn is well rounded. The base is short, somewhat inflated, well 

 rounded. The aperture is oblique, broadly oval. The peristome is 

 somewhat expanded and reflected and slightly thickened. The 

 columella is oblique, slightly excavated. 



The specimen described and figured (U.S.N.M. no. 313605) was 

 collected by Quadras at Baco in northeastern Mindoro. It has 5.2 

 whorls and measures: Length, 36.2 mm; greater diameter, 27.6 mm; 

 lesser diameter, 24.5 mm. 



A series of specimens (U.S.N.M. no. 313603), collected by the 

 Menage Expedition in northeastern Mindoro, collector's no. 45, yields 

 the following measurements:
