EUTAEXIA LEPTOCEPHALA. 



tion. The lores, labials, cheeks, and head beneath, are greenish-white, 

 gradually shading into the slate hue of the abdomen. 



In another specimen, with the general color very dark, the vertebral 

 line occupies one and two half-scales throughout. The black on each 

 side appears formed by the confluence above of about seventy-six spots 

 from head to anus, each spot from one and a half to two scales long. 

 The lateral stripe is on the second lateral row of scales, of a greenish- 

 white color, and confluent with the intervals of the spots, also of the 

 same color. The stripe is not well defined, but swells and narrows 

 like a knotted cord. The exterior row of dorsal scales and the sides 

 of the abdomen are deep blue-black, becoming greenish toward the 

 middle of the abdomen ; anteriorly, the color shows more white. 



Loc. This species was collected up Puget Sound, Oregon.
