(5g4 REPORT OF NATIONAL MUSEUM, 1898. 



upper ones of opposite sides separated by a width of six scales There 

 is a faint trace in the typical specimen of a pale vertebral line with 

 a dark border on each side, and there is a black border above the 

 upper lateral line and another below the inferior lateral line. Ihese 

 lines extend to the orbit and ear respectively. The superior labials 

 are green, black bordered; the other head plates brown with black 



The elevated form of the loreals and undivided mental plate ally this 

 species to the E. anthracinus. The more numerous scales and labial 

 plates the wide interfrontonasal and different coloration distinguish it. 

 From K pachyurus its well-developed limbs separate it. In K brevih- 



neatus the loreal plates are differ- 

 ently formed and the coloration is 

 totally different. The size is rather 

 small. But one specimen of this 

 species is known. It was taken near 

 Mobile, Alabama, by Dr. Joseph Cor- 

 son, U. S. A., well known by his im- 

 portant additions to Eocene verte- 

 brate paleontology. It is preserved 

 in my private collection.

 Nat. Mus., No. 17, 1880, p.l8.— BoUL- 

 ENGER, Cat. Liz. Brit. Mus., Ill, 1887, 

 p. 376. 



No postnasal plate; anterior loreal 

 not elevated, reaching interfrontona- 

 sal, its posterior border striking the 

 middle of the second labial ; second 

 loreal longer than high; two preocu- 

 lars between fourth and fifth superior 

 labials. One large pentagonal men- 

 tal. Scales in twenty-six longitudinal rows. Hind leg two and one- 

 half times in length of head and body, and meeting the fore limbs when 

 both are appressed on the side. 



Color plumbeous above, light olive below. A light band extends 

 along the upper lip to a short distance behind the axilla, and another 

 from the end of the muzzle over the eye to the corresponding point on 

 the side, separated by two longitudinal rows of scales. 



Measurements.— The total length is 170 mm.; from muzzle to vent, 59 

 mm. ; length from muzzle to ear, 12 mm. 



This plainly colored skink is intermediate in characters between the 

 E. anthracinus and the E. tetragrammus of Professor Baird. It has the 

 single mental plate of those species, but the prefrenal is not high; 

 There are twenty-six rows of scales, and there are no lateral bands on 



Fi-. 137.
