for about 35 miles, then directly north 16 miles on Eagle Creek to 
the southern rim of the Blue Mountains. Pupas and Vallonias were 
found at Honeymoon Ranger Station, and Oreohelix a mile or two 
farther on, fifty miles from Clifton. 
The rim of the Blue has a wall of broken granite. We found 
Ashmunella mogollonensis and a grayish form of Oreohelix cooper, 
the latter also in the quaking asp and cork-bark fir groves of the 
vicinity. 
The route lay northwesterly again, across the KX. P. cienaga, 
down Corduroy and Fish Creeks and across Black River, to Reser- 
vation Creek in Apache Co. This high plateau has a continuous 
forest of the largest yellow pine, blue spruce, Douglas spruce, thickets 
of quaking asp and alder. Pupwe and Oreohelix were the prin- 
cipal snails. Few were found on the dome-like summit of Mt. 
Thomas. 
Along Black river Oreohelices, from pale to nearly black, from high 
to low, were in every rock pile. 
On the return trip the Raspberry trail from the rim of the Blue 
Mountain to Cosper’s ranch on the Blue river was taken. Down the 
Blue and San Francisco rivers Ashmunella, Sonorella and Oreohelix 
were found in the slides investigated, but the journey was a hurried 
one. This ground was thoroughly covered in the journey of 1914. 
An account of the journey of 1913 may be found in. Nautilus for 
January, 1919. 
On the expedition of 1914, Ferriss was accompanied by Mr. L. E. 
Daniels.» Part of the route taken in 1913 was retraced—from 
Clifton, Graham Co., Arizona, up the San Francisco and Blue 
Rivers to Cosper’s ranch, a distance of about 50 miles. From this 
point they continued up the Blue River, northeast, to its head, and 
to Luna, Socorro Co., New Mexico. From Luna the party turned 
southeast, across the San Francisco Mountains (which lie south of 
Luna), and by way of Alma to the Mogollon Mountains. Some 
account of this trip was given in Nautilus XXVIII, February, 1915, 
pp. 109-113. The Ashmunellas collected were described and figured 
in Nautilus X XIX, June, July and August, 1915, to which the reader 
is referred for these matters. A map showing the collecting stations 
in the Mogollons may be found on page 331. 
5 We have to record the death of Mr. Daniels, October 23, 1918. He was 
a companion of both authors on collecting trips of some months’ duration, and it 
is a real sorrow that he will no longer share the labors of the trail or the cheer of 
the evening camp fire.
