620 ZOOLOGY REPTILES AND BATRACHIANS 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 ; annnlus 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 boi/lii)." Cope.

"Resembles the P. graham-iac (Salvadora graliam'm, 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 Onemidophoms wrl'meatm.
