EUTAINIA. 35 



ally to one and two half-rows, at which it continues to the tail. On 

 each side is a well-defined stripe of greenish yellow along the second 

 and part of the third outer row, and contrasting decidedly in color 

 with the vertebral line. The blackish brown color is strongly defined 

 between the stripes, below them the greenish white sides and abdo- 

 men are tinged with brown, (on the exterior dorsal and ends of ab- 

 dominal scutelltC.) The bases of the scales on the exterior dorsal 

 row are black, which sometimes shows when the scales are separated, 

 though usually covered by the incumbent edges. 



The species is readily distinguished from its nearest analogue, 

 E. in/ernalis, by the darker color of the sides, the ochraceous dorsal 

 stripe, smaller head, number of dorsal scales, &c. It has a strong 

 resemblance to U. proxima in distribution of color, but is stouter 

 and shorter, and has the lateral stripe on the 2d and 3d rows, not on 

 the 3d and 4th.

A second specimen, belonging to the Boston Natural History So- 

 ciety, has precisely the same markings, although with but 19 dorsal 

 rows. As usual in young individuals, it has black spots along the 

 sides upon an olivaceous ground, with which they are confluent. 

 Above the lateral stripe are seen from 80 to 90 black spots from 

 head to anus, as well as a series of small ones below the line.

14. E^utainia vagrailS, B. & G.— Above light brown, beneath 

 slate-color. Vertebral light line on a single row of scales. Two series of 

 small black spots, about 100 in number, on each side. 



Above light brown ; beneath slate-color, (sometimes black,) with 

 the margins of the scutellaj black. A dorsal line occupying a single 

 row of scales, of a dull yellowish color, the tint occasionally running 

 into the marginal row. On each side of this, two series of small 

 black spots occupying generally a single scale, and varying from 95 

 to 105, from occiput to anus. The upper series is in the 2d row 

 from the vertebral, the lower in the 7th. 



Compared with its nearest neighbor, E. leptocephala, it differs in 

 having the exterior row of dorsal scales large and carinated, the next
