22 ON THE ZOOLOGICAL. POSITION OF TEXAS. 



It is evident that these varieties pass into each other completely. 



Tropidoclonium Uneatum Hallow. Obtained near Dallas by Mr. Boll. 



Storeria dekayi Holbr. From Dallas, Houston, and Helotes. 



Tropidonotus clarld Baird and Girard. From Dallas and Houston. 



Tropidonotus rliombifer Hallow. From Dallas and Helotes. This 

 large species, heretofore only known from the Lower Mississippi, may 

 now be regarded as a resident of the entire low country of Texas. I 

 did not see it in the plateau region. 



Tropidonotus sipedon tvoodhousei B. & G. From Fort Worth west to 

 Fort Mason, and to Helotes. A specimen from the first locality- has the 

 abdomen uniform light yellow. In the young the spots are much more 

 distinct than in the adult. 



Tropidonotus fasciatus L. From Mr. Boll's collection made near 

 Dallas. 



Eutcenia marciana B, & G. Abundant near Helotes and San Antonio, 

 but not procured by Mr. Boll near Dallas. 



Uutccnia cyrtopsis, subsp. ocellata. Scales in nineteen longitudinal 

 rows, the inferior smooth anteriorly but keeled x)osteriorly. Eight supe- 

 rior labials; loreal higher than long; temporals 1-2-3, the anterior 

 large. The lateral band on the second and third rows of scales cream 

 colored; dorsal band, extending to the end of the tail, orange-red. The 

 usual alternating square black spots between the two bands ; the scales 

 in the light interspaces black or deep brown. Anteriorly the lateral 

 black spots unite into a single series of subquadrate spots. The lower 

 borders of the lower series of spots invade the lateral band, sometimes 

 cutting it entirely off into sections of regular length. Below the middle 

 of each section, and therefore alternating with the inferior lateral spots, 

 is another black spot, relating to the arched light bar above it, as i^upil 

 to eyebrow. The superior lateral spots in like manner invade the me- 

 dian dorsal baud, either cutting it oft" entirely or giving it a laterally 

 uudulatory course. Its width is alternately one and one and a half rows 

 of scales. A dark gray shade connects the lateral inferior spots. In- 

 ferior surfaces olive-lead colored; the gastrosteges with blackish bases 

 at the extremities. A large black spot behind the occipital plates, ex- 

 tending to below the angles of the mouth, which is deeply notched 

 behind by the dorsal band. No occipital spots. Labial plates yellow, 

 all equally black-edged. No yellow crescents on the side of the head 

 or neck. Total length, m. .GOO; length of rictus oris, .020; of tail, .035. 

 This handsome subspecies of the genus was discovered near Helotes,
