The following species are believed to be new : 

 Vitrinella mooreana n. sp. Fig. i. 



Shell umbilicate, discoidal, with about 4^ whorls. The first whorl 

 is yellow and smooth, the remaining are white and sculptured with 

 heavy spiral cords, of which there are 5 on the 

 penultimate whorl and 7 on the body whorl above 

 the periphery. The granulate interstices are 

 about as wide as the spiral cords. The base is 

 sculptured with very faint spiral striae. The 

 aperture is oblique and suborbicular, with the 

 columella broadly thickened. 



Alt. 1.2, diam. 2.75; aperture alt. 1, diam. 1 

 mm. 



This species was collected by Mr. Clarence B. 

 Moore on the gulf side of Crooked Island, off 

 St. Andrew's Sound, Calhoun county, Florida. 

 The types are No. 84,611, A. N. S. P. It is named 

 in honor of its collector, Mr. Moore. The species 

 seems to be near V. multistriata Verr., but differs 

 in having 7 strong spiral cords above the 

 periphery and a nearly smooth base. It differs 

 in having a thickened columella.
