a lengthy streak of black and yellow. I found it impossible to secure speci- 

 mens till I hit upon the expedient of shooting them with a small charge of 

 mustard seed shot out of an old fashioned pistol ; with which 1 could procure 

 any quantity ot them. They live chiefly in high dry open woods, among dry 

 leaves, at the feet of bushes, etc. They are emphatically ground lizards, not 

 tree or rock species." 



Plistodon o b s o 1 e t u s Bd. Gird , 1. c. 1852, 129. 



Plistodon guttulatus Hallowell, Proc. Acad. Phila,, 1852, 206. 

 Fort Whipple. 



OPHIDIA. 



Asinea. 



Contia i s o z o n a n. sp. nov. 



Char. Two postoculars ; six rows of gular scales. Rostral rounded, slightly 

 produced backwards. Scuta 158 1, 52. Twenty black half rings, separated 

 by equal spaces of pinkish ground color. 



Descr. Eye small, diameter twice in length of muzzle. Preorbital nar- 

 rower above, not extending above lower margin of superciliary ; loreal twice 

 as long as high. Prefrontals and internasals much broader than long; frontal 

 slightly angulate in front, longer than broad ; parietals rather elongate, sub- 

 truncate behind. Postorbitals subquadrate, temporals 1 2. Postgenials 

 minute. Superior labials seven, all higher than long, eye over third and 

 fourth. Scales in fifteen rows, all broader than long. Tail four and two-fifths 

 times in total length, which is 10-25 inches. Below immaculate; tail com- 

 pletely six-annulate. 



Another specimen from the Museum Smithsonian, from Rockville, Kane Co., 

 Utah, from A. L Siler, indicates a variety. The body is longer than in the type, 

 and is crossed by twenty-five black bars, between these and on top of muzzle 

 Vermillion, below yellow. Scuta 167 I 52. Both specimens resemble the 

 Sonora semiannulata B.&G., but that species has two nasals, three 

 postoculars, the superior reaching the frontal ; frontal wider behind than 

 before, and only 149 gastrosteges. 



Rhinochilus 1 e c o n t e i Bd. Gird., Catalogue 120. 



A well marked variety, having fewer (twenty) black half rings on the body 

 extending to the gastrosteges and separated by a narrow interval. Abdomen 

 with subquadrate black spots opposite the former and their intervals. Other- 

 wise as types. 



Phimothyra h e x al e p i s n. sp. nov. 



Resembles the P. grahamiae [Salvadora B. G ) 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 pre- 

 oculars ; two or three loreals largest higher than long; nostril 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 mar- 

 gius are ochriceous at base. Rostral plate well developed, higher than broad. 

 Nasals elongate, much depressed, anterior extending behind first labial; post- 

 oculars two ; two long narrow temporals. Width of occipitals nearly equal 

 common suture. Nine superior labials ; first pair inferior labials much dila- 

 ted medially, their common suture nearly equal that of pregeneials. Scales 

 seventeen rows. Gastrostages 176, urosteges 75. Tail and below uniform 

 yellowish.
