 the vertebral line occupies cue 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 oue and one-half 

 to two scales long. In other words, there is a stri})e of black three and 

 one-half scales wide on each side of the vertebral line, confluent with 

 which is a series of black spots on each side, as indicated. The lateral 

 stripe is ou 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. Exterior row of dorsal scales and sides of abdomen deep blue- 

 black, becoming greenish toward the middle of the abdomen; anteriorly 

 the color shows more white. The intervals between the lateral spots 

 are very narrow, and anteriorly are wanting, producing the coloration 

 of the E. s. trilmeata. Scuta, 170-1-80.

Four specimens, two from Tacoma, and one each from Hatzig and 

 Sicamoos, British Columbia, were obtained by Mr. S. N. Bhoads. 

 The last two specimens are typical E. s. trilincatK, but in the two from 

 Tacoma the dorsal stripe marks only a single row of scales, and the
