Cosiquiriachi, west of Chihuahua. This species has borne flower 
and fruit with me, and my notes and my recollections indicate that 
they were central: hence the mark of doubt above, as to the proper 
position of this species here, where all the other closely allied 
forms belong.

From the Gila to the eastern slope of the: California mountains. 
— The name originally given had to be altered, because very rarely, 
if ever, are 4 hooked spines seen. In the original mein Ae this 
and the next species were confounded. — Plant 2—4 inches high. 
Radial spines 4—6 lines, central ones 5-9 lines long. — Apparently 
. near M. ancistroides, Lem., which, however, has the radial spines 
all homogeneous.
