CROCODILIANS, LIZARDS, AND SNAKES.

little bent dowu laterally. Frontal three to four times as long as least 

 width; lateral outlines not straight. Supraoculars broad; occipitals 

 rather short; longer than broad, the length equal that of the frontal; 

 two unequal postoculars in contact with one temporal. One preocular 

 just touching frontal ; one longitudinal loreal, higher behind, frequently 

 wanting. One elongate nasal, the nostril anterior to its nuddle and 

 frequently connected by a suture to the margin below. Superior labials, 

 eight; third, fourth, and fifth entering orbit; inferior, ten; five in con- 

 tact with pregenials, which are longer than postgenials. Anterior 

 maxillary and mandibular teeth longer than median. Pupil round. 

 Scales broad, thin, poreless, in nineteen rows. Tail rather slender. 

 Gastrosteges, 173-9^; one divided anal; urosteges, 69-73. 



Measurements. — End of muzzle to rictus oris, 13 mm.: total length, 

 582 mm.; tail, 112 mm. 



General color light brown, punctulate with dark brown, especially 

 thickly on head and sides. A darker brown band three and two half 

 scales wide, from occiput to end of tail, which is nearly broken into 

 spots on the nape. Ends of scuta and first two rows of scales darker, 

 especially anteriorly where the band is sooty and spreads over the lips 

 and chin; a faint longitudinal band above the shade; a short yellow, 

 dark bordered streak from postorbitals to penultimate labial. Abdomen 

 with many short punctulate streaks. With age the bands become more 

 indistinct, so that nothing remains of the one on the dorsal region but 

 its external borders. 



Of the seven specimens at my disposal three have a loreal plate and 

 four have none, its place being taken by the decurved prefrontal. In 

 one specimen there are eight superior labials, the excess appearing in 

 front of the line of the orbit. 



In all of my specimens the frontal plate is relatively narrower than 

 in the specimens figured by Jan, and described by Boulenger. Its least 

 width enters the length from three to four times, while those authors 

 give it as entering two and a half times.

According to Boulenger, the British Museum has received this spe- 

 cies from La Cumbre de los Arrastrados, in the State of Jalisco, Mexico, 

 from an elevation of 8,500 feet. This habitat brings it within the Medi- 



' My original description gives the gastrosteges as one hundred and eighty-six, but 

 in none of the five specimens at my disposal does the number exceed one hundred 

 and seventy-nine. The former number is probably a misprint for one hundred and 

 seventy-six.
