scales. A black band bordering itoccupies the remaining half of tbe row 

 with the adjacent half of the next row. The remaining half of the next 

 row is occupied by a pale band. A black line passes along the adja- 

 cent edge of the next row, whose middle is white. The external edge 

 of the same row is involved in the superior edge of a wide band, which 

 covers two rows and two half rows. Thus there are three dark bands 

 on each side of the middle line, the inferior being the widest. Alto- 

 gether they cover only five and a half rows of scales on each side. 

 There are also no lateral light bauds, as in many species, but the color 

 of the abdomen extends to the lower dark baud. Size rather small; 

 length of head and body, 70 mm. 



This species is allied to the IJ. leptogrammus Baird. Most of the speci- 

 mens of that species have twenty-six rows of scales, but one of tliem 

 has twenty-four. In all the specimens of the latter the internasal is 

 relatively larger, equaling, or nearly equaling, a prefrontal; in E. epi- 

 pleurotus it is about half as large as a prefrontal. The rostral plate in 

 U. epipleurotns is more elevated and acuminate above, its lateral labial 

 border being about one-third the remainder, while in E. leptogrammus 

 it is more than half the length of the same. The anterior vental is 

 smaller. The appressed limbs of the E. leptogrammus touch each other. 

 It is possible, but very uncertain, that Boulenger is right in supposing 

 E. epipleurottis to be the adult of E. leptogrammus. 



I find but one specimen at present in the U. S. iSTational Museum 

 which is the original type.

Head short, rather broad, and with the lateral protile sloping con- 

 siderably^ or quite convex. Cephalic plates much as in (juhiquelineatus, 

 though the posterior postnasal sometimes entirely above the first, or 

 divided in two. Seven upper labials. Limbs short and weak. Hind 

 leg laid forward twice reaches midway between arm and ear, and 

 from foot is about one-third the head and body; from knee is contained 

 nearly four times. Fore leg from elbow is not equal to head from 

 snout to ear, which again is contained four and one-half times in head 

 and body. Tail one and one-fourth times the head and body; cylin- 

 drical. In one specimen twenty-four rows of scales around the body; 

 the median scarcely wider, and fifty-eight from head to tail; fifth hind 

 toe shorter than second, free portion two-fifths the size of head to ear.
