nence, and their number, about So, not 70. The lateral stripe is 

 nearly absent, and the dorsal quite indistinct. The lower row of 

 blotches is below and along the place of the lateral stripes. The oc- 

 cipital black patch is much larger than in. E. sirtalis, and the labials 

 more margined. 



From E. Marciana, which it resembles, the want of the light 

 patch behind the mouth, and the different number of dorsal rows will 

 always distinguish it.

11. Etltainia ordiuoides, B. & G. — A dorsal and two lateral 

 stripes. On each side two series of black spots, about 80 in number ; be- 

 tween the lower series reddish brown; between the upper olivaceous. Dor- 

 sal rows 19-21. Eody stouter than most species. Exterior row of dorsal 

 scales tlie larger, carinated. Remaining scales neai'ly equal. Caudal 

 scales strongly carinated.

A very strongly defined dorsal stripe of a yellowish color, occupy- 

 ing one and two half-scales. A second line less distinct along the 2d 

 and 3d rows from the abdomen. On each side^ between the dorsal 

 and lateral stripes, are two series of subquadrate black spots, 80 to 

 84 in number, arranged alternately, and occupying portions of seve- 

 ral scales; the spots in the lower series larger. Intervals between 

 the lower series of spots occupied by reddish brown scales, in shape 

 and color somewhat resembling the dead leaves of the hemlock, 

 (^Ahks canadensis). Intervals between the upper series olivaceous 

 brown, more or less blended with the black. Beneath uniform green- 

 ish white, with bases of the scales black, as they are also on the more 

 exterior dorsal rows ; this color, however, rarely shows beyond the 

 margin of the incumbent scales. 



In one specimen, which is much larger than the others, the dorsal 



spots form a rather narrow margin to the broad dorsal stripe, and are 



more or less confluent with the ground-color. Space between the 



lower row of spots pale reddish. Dorsal scales 19. Ninety spots 



from head to anus. 



The characters arc very strongly marked, and easily recognised.
