Diagnosis. — Similar to £^. skiltonianus, but tail salmon 

 color instead of blue, and with interparietal smaller than 

 either frontoparietal instead of larger.

Description of the Type. — The nasal is small, in contact 

 with the internasal, postnasal, first labial, and rostral plates. 

 The postnasal touches the nasal, internasal, anterior loreal, 

 and the first and second labials. The anterior loreal forms 

 sutures with the postnasal, internasal, frontonasal, pre- 

 frontal, second loreal, and second and third labials. The 

 three anterior of the four supraoculars are in contact with 

 the frontal. The interparietal is smaller than either of 

 the frontoparietals. The parietals are in contact poste- 

 riorly. The last of the seven labials is largest. There 

 are two azygos postmentals. The limbs overlap when 

 pressed against the body. There are twenty -four long- 

 itudinal rows of scales. The dorsal scales are larger 

 than the laterals and ventrals. There is a median series 

 of transversely enlarged subcaudals, on each side of which 

 the other caudals become gradually smaller dorsally. 



The ground color above and on the sides is dark olive. 

 There are two bluish gray lines on each side. The up- 

 per of these lines originates on the internasal plate, crosses 

 the anterior loreal, prefrontal, supraocular, and parietal 

 plates, and runs along the dorsal scales (second and third 

 rows from the median line) to the tail. The lower trav- 

 erses the labial plates, crosses the ear opening, and runs 

 along the side of the neck and body to the hind limb, 

 -forming the lower boundary of the olive ground color.
