Scales in iiiiieteeu rows ; no longitudinal bands. Olive brown, with 

 four series of small black s})ots, and a trace of two exterior anteriorly; 

 eight superioi- labials, all liigher than long except the seventh, no black 

 margin on the sixth or posterior margin of eighth, but a strong black 

 baud from eye across jjosterior margin of seventh to mouth. Sides of 

 head white, extending upward as two areas, margining each occipital; 

 behind each a black nuchal spot separated by a narrow white line from 

 its fellow and extending over occipital plates and half of frontal; pre- 

 frontals transverse. 



The markings of this species are entirely peculiar; it is also dis- 

 tinguished by the transverse or narrow prefrontals and internasals. 



To this description 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 ; orl)itals, 1-3. There is a trace of a dorsal stripe on the 

 nape, which divides the nuchal spot into two. iS"o postoral crescent. 

 Below the square lateral spots on the sides of the neck is a row of 

 smaller, alternating scpiare spots, which serve to define a lateral stripe 

 for a short distance. Su|)erior 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, one hundred and forty-eight; uro- 

 steges, sixty-five. 



MeasurementH. — Total length, 205 mm.; length of tail, (J."* mm., or one- 

 fourth of the total.

Bocourt reports this species as having been sent from C)oban, Vera 

 Paz, to the Museum of Paris. I have it also from Zacualtipan, in the 

 State of Hidalgo.
