NOTICES OF NEW SPECIES AND VARIETIES OF AMERICAN LAND 



SHELLS. 



BY HENRY A. PILSBRY. 



The following forms were included by name in the recently pub-

 been described. 



Epiphragmophora arrosa var. expansilabris n. v. 



Compact and globose-turbinate, imperforate or nearly so, wrinkle 

 striate, malleated in places ; band above periphery broad and dark ; 

 spire conic, whorls 5f ; lip very broadly expanded, reflexed below, 

 thickened within, white. Alt. 19-20, diam. 23-25 mm.

 Academy by Mr. John Ford. 



Polygyra lawse var. tallulahensis n. var. 



Very small, shaped like P. jejuna Say, the peristome expanded, 

 subreflexed, thickened within, no teeth or lamellae; umbilicus 

 minute. Whorls 4, the last with a slight ridge or crest and then
