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 Ashmunellas. 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.
