square and arranged in spiral rows (Philippic and specimens from 

 C'liiliiialuia), or more irregular and combined, sometimes at acute 

 angles (specimen Irom \'cntanas_). Jn a >pecimen from Chihuahua 

 tin 1 pale spots of the type are seen within some of the larger torowu 

 patches. The -culpture of this species is somewhat coarsely rugoso- 

 striate, hut it cannot he termed undulated, as in (>. h in^triitiis Pfr. 

 Mn.-t of the specimens I have M en show reinarkahle irregularities 

 and scars, r-onie even at the apex, caused hy previous fractures dur- 

 ing life. Probably they live on conspicuous objects during the wet 

 season, and often fall to the ground. (Mur/i'/is.)
