THE NAUTILUS. 41 
Jose peak, where Sonorella mearnsi dwelt at the time of the 
Boundary Survey. 
Bound for the Huachucas to pick up better sets of former 
collections, we dropped down the Patagonia mesa through a 
thick grove of young oaks with cultivated ranches in the can- 
yons. Then out upon a Kansas prairie landscape where the 
highway crosses the head of the Santa Cruz running south and 
the Barbacomari running north. Here are a number of prairies, 
without brush or thorns as beautiful to the eye as any state can 
produce. The Canillo Hills for thirty miles or more are covered 
with a thick growth of oak and juniper. At the high peak east 
of our road we found Sonorella elizabethae in abundance, and in 
the limestone hills west were small colonies of Holospira for 
three miles under spawls close to the stratified terraces, but a 
foot or so in height. Also in the rocky hillsides. 
Across another beautiful prairie we were again in the Huachu- 
cas at the Manilla mine, at the northwestern end. Here we 
were comfortably housed at the property owned by some of my 
Joliet friends, and at the home of the typical Holospira ferrissi 
Pils. It seemed convenient to have lamps and a cook stove. 
Again we camped in Carr Canyon, near the home of our friend 
Biederman the entomologist and father of walnut grafting. Side 
trips were made to Garden, Brown, Miller and Ash Canyons. 
Around the southeast point of the range we went into new 
territory, Montezuma and Copper Canyons, and again gathered 
Ashmunella heterodonta at Ida Canyon. These are rich canyons 
and so extensive they have not been thoroughly explored. One 
of the smallest of Sonorellas turned up in Montezuma Canyon, 
Sonorella montezuma. It was found abundant in lime, granite 
and porphyry. Again we had splendid quarters, a stove and 
lamp, on the State of Texas mining property. These mountain 
ridges run into Mexico, and ranchmen obtain permits from the 
Mexicans, when they desire to journey into Tombstone, Naco 
and Douglas with a vehicle. 
From the Huachuca camps several raids were made on the 
Mustang and Whetstone ranges about twenty miles away. The 
first range, about 6,000 feet, has shells in every stone-pile, and 
the climbing is easy and clean. It is a model for collectors to
