620 ZOOLOGY— REPTILES AND BATKACHIANS OF ARIZONA. 



pletely divided, those on the following third of the length being divided by 

 red on the sides ; the remaining annuli black, three scales wide ; white an- 

 nuli one and one-half scales; anterior or nuchal red; annulus widest, its 

 anterior black margin attaining parietals ; an ochraceous band from gular 

 region, not quite completed across parietals. Muzzle, prefontal plates, and 

 labial margin ochraceous ; remainder of top and sides of head black. Total 

 length, 30.5 inches. 



"This species has a longer body than the known red-ringed species, 

 and is, indeed, most closely related to the 0. boylii. It will always be dis- 

 tinguished for the latter by the much more numerous annuli (twenty-eight 

 in boylii)." — Cope.

"Resembles the 7'. grahamice (Salvadora graJiamice, B. & Gr.), but differs 

 in having a shorter tail, five and one-third times in length, instead of four 

 times; eye resting on sixth supralabial, on account of the presence of three 

 narrow preoculars, two or three loreals — largest higher than long; nos- 

 tril on suture between nasals and internasals ; dorsal stripe narrow — one 

 and two half scales, and lateral brown band wide, four and a half to five 

 scales, whose superior margins are ochraceous at base. Rostral plate well 

 developed, higher than broad; nasals elongate, much depressed, anterior 

 extending behind first labial; postoculars two; two long narrow temporals. 

 Width of occipitals nearly equal common suture. Nine superior labials; 

 first pair inferior labials much dilated medially, their common suture nearly 

 equal that of pregeneials ; scales seventeen rows. Gastrosteges, 176 ; uro- 

 steges, 75. Tail and below uniform yellowish." — Cope. 



Fort Whipple. The stomach contained a Qnemidophorus sexlineatus.
