In a former paper 21 we mentioned a form of Ashmunella from Miller 

 Canyon, Huachucas, which, so far as the shell is concerned, agrees 

 exactly with A. chiricahuana. 



Specimens collected in 1907 have now been dissected. The Huachu- 

 can form proves to be practically identical with A. levettei in the soft 

 anatomy, and abundantly distinct from A. chiricahuana in the pro- 

 portions of the organs, especially of the spermatheca and its duct, 

 as will be seen by the following table: 



A. chiricahuana, Huachuca Mt. 



Chiricahua Mts. form. 



Length of vagina 9 mm. 7.2 mm. 



" " spermatheca and duct 56 " 26 " 



" penis 4.5 " 7.3 " 



" epiph alius and flagellum 68.5 " 40 



The spermatheca in the Huachucan form has the long, cylindric, 

 weakly sacculate shape of that of A. levettei, wholly unlike that of 

 A. chiricahuana. This form has been fully described and figured in a 

 former paper. It is undoubtedly the shell indicated as A. chiri- 

 cahuana var. varicijera Ancey, and will now be called Ashmunella 

 varicifera.

The type locality is not in Barfoot Park proper, but in a small park 

 of yellow pine on the road from Paradise, about a mile before it crosses 

 the ridge or divide going to Barfoot. This Is the first grove of yellow 

 pine on the road up. The type locality is a small conical pile of earth 

 and rocks about ten feet to the left of the road. 22 It was covered 

 with snow at the time of our visit, but a small series of living specimens 

 was taken, No. 92,205 A. N. S. P. About a mile below this place, 

 toward Paradise, where a few yellow pines first appear among the oak 

 scrub, we found a few examples. It will probably be found in many 

 other suitable places in this immediate vicinity, reached by the road 

 from Paradise to Barfoot Park. Our work in this place was impeded 

 by a heavy snowfall, which lay knee-deep among the pines. 



In the topotypes (No. 92,205) the diameter varies from 14.5 to 16 

 mm., whorls 6 to 6^. The degree of elevation of the spire is quite

22 We would ask future collectors to preserve this small type colony by taking 

 only a moderate number of specimens there.
