suture. Sculpture, evidently irregularly punctate, no signs of 

 lirae. 



S. hinkleyi Walker. Apical whorls more or less elevated, 

 bluntly rounded. Apical whorl flatly rounded, not constricted 

 by the suture, apex immersed. Sculpture, very finely and 

 irregularly punctate above and more or less lirate below. 



S. hamerosus Walker. Apical whorl much elevated, everted, 

 rounded and constricted by the suture. Sculpture, punctate 

 above and lirate below. 



S. integer Say. Apical whorl not everted, flatter than in 

 subglobosns. Sculpture, scarcely more than wrinkled, no lirse. 



S. mexicanus Pilsbry. Apical whorls elevated, rather pyra- 

 midal, more so than in any other species, closely coiled, rather 

 acutely pointed. Apical whorl only slightly everted, not con-

THE NEW MEXICAN EXPEDITION OF 1914— ASHMUNELLA. 



BY H. A. PILSBRY AND JAS. H. FERRISS. 



( Concluded from page 35 ) . 



AsHMUNELLA DANIELSI DISPAR n. Subsp. PI. 2, fig. 2. 



Smaller than A. danielsi, composed of 5 whorls, and like that 

 in having no trace of a parietal tooth. The long tooth in the 

 outer lip is strongly developed. The two basal teeth are nearer 

 together, and more or less completely united or sometimes fused into 

 one. The umbilicus enlarges very little at the last whorl. 



Height 5.8, diam. 11.2 mm. 



Smallest adult, diam. 9.8, largest 11.25 mm. 



Locality. — Station 55 (1914), Little Whitewater Canyon, 

 Mogollon Mountains. 



One of the smallest Ashninnellas. It runs parallel to A. 

 duplicidens of the Chiricahua range in structure of the basal 

 teeth . 



One hundred examples were collected. No other shells were 

 found at this station except a few of the smaller families.
