black scale-borders, those of the inferior row the more distinct. A similar 

 row of black edges on the first row of scales. All of these spots become 

 distinct on the sides of the neck. Nuchal spot large, black, and with a 

 shallow notch behind ; no occipital or other spots on the head. The gas- 

 trosteges have black bases, a character not seen in any of the other species 

 here referred to. 



Gastrosteges, 151. Total length, M. .430; of tail, .135, or one-third the 

 total. 



This handsome species was obtained at Orizaba, Vera Cruz, by Dr. 

 Sumichrast. 



EtJTJENIA PULCHRILATTJS, sp. tiOV. 



At first sight this species looks like the E. flavilabris Cope, but it has 

 characters of the E. collaris, and adds some of its own. " 



The dorsal stripe, as in E. collaris, occupies but a single row of scales. 

 The lateral stripe, occupies the adjacent edges of the second and third 

 rows. The entire front row is covered by a broad brown band, which 

 defines the lateral light band very distinctly below. This is not seen in 

 either of the species above named. There are two rows of black spots 

 between the dorsal and lateral bands, but the keels of all the scales 

 involved in them are brown. There are no spots below the lateral light 

 line, either on the neck or elsewhere. A large nuchal black spot, which is 

 notched behind by the median band. No postoral crescent. Head above 

 brown ; lower surfaces uniform greenish, except tail, which is yellowish 

 below. Occipital spots very indistinct. 



The head is not very distinct from the neck. The frontal plate is wider 

 than the supraorbitals. Gastrosteges, 158 ; urosteges, 67. Total length, M. 

 .465; of tail, .105. 



One specimen from Dr. Duges ; locality uncertain, but probably Guana- 

 juato.

To the description already given, I add some notes taken from a third 

 specimen. The frontal plate is wider than the supraorbitals. There are 

 eight superior labials, and the orbit is bounded by the fourth and fifth. 

 Temporals, 1-2; orbitals, 1-3. There is a trace of a dorsal stripe on the 

 nape, which divides the nuchal spot in two. No postoral crescent. Below 

 the square lateral spots on the sides of the neck is a row of smaller, alter- 

 nating square spots, which serve to define a lateral stripe for a short dis- 

 tance. Superior labials brownish yellow, brown edged. Inferior surfaces 

 uniform dirty yellow. 



The keels of the scales are very strong, except those of the first row, 

 which are obsolete. Gastrosteges, 148; urosteges, 65. Total length, M. 

 .265 ; length of tail, .063, or one-fourth the total. 



The locality whence the typical specimens of this species were obtained 

 is Orizaba, Yera Cruz. The locality of a third specimen is uncertain. It
