PSEUDOFICIMIA Bocourt. 

 Pseudoficimia Bocoukt, Miss. Sci. Mexique, Reptiles, 1883, p. 572. 



Grooving of posterior maxillary teeth obsolete. Nasal plate divided 

 below the nostril, which is below the internasal suture. Internasal 

 plates present; rostral prominent. Anal and subcaudals divided. 

 Pupil round. 



This genus is nearly allied to GhionacUs, but the teeth can not be 

 said to be grooved, and the nasal is partly divided. For these reasons 

 I formerly referred the typical species P. fronfaHs to Gcagras, but Dr. 

 Boulenger points out that that genus is characterized by the position 

 of the nostril at the junction of the nasals and internasal, which is not 

 the case in this species. But one species of this genus is known.

Muzzle prominent, acuminate, slightly recurved. Kostral separating 

 prefrontals very slightly. Nasal long, divided below the nostril; no 

 loreal; postfrontal in contact with second superior labial. One narrow 

 low preocular, two postoculars, the lower barely in contact with one 

 temj)oral; temporals 1-2-3. Seven superior labials; eye over third and 

 fourth. Occipitals longer than frontal, truncate, rounded behind; 

 anterior suture of frontal a little longer than straight, lateral. Seven- 

 teen rows of equal thin scales. Seven inferior labials; geneials very 

 short, posterior pair reduced to scales. Urosteges, forty-four; one 

 double anal; gastrosteges, one hundred and forty-one. 



Measurements. — End of muzzle to canthus oris, 15 mm.; to vent, 406 

 mm.; length of tail, OG mm.; total, 502 mm. 



Color below uniform pale yellow; above grayish brown, becoming 

 more rufous medially, with about thirty-six rhombic, dark-edged brown 

 spots, six scales wide and four long, whose angles are produced as 

 vertical lateral bars. Together they become nearly crossbands poste- 

 riorly, when they are separated by a pale spot on the vertebral line. 

 A brown cross-band across prefrontals and frontal; a longitudinal 

 band on each occipital and side of nape. 



This is one of the species which range from the Sierra Caliente at 

 Colima to the Austroccidental plateau at Guadalaxara.
