_Remarks._--In his diagnosis of _C. l. lineatus_, Smith (1941:122) states: "lateral dark stripe ... very narrow posterior to nape, extending along fourth scale row; posteriorly a stripe along third and eighth (farther posteriorly the seventh) scale rows; a narrow dark stripe along sixth scale row, continuous throughout length of body...." I fail to find a dark stripe on the 6th row throughout the length of the body. In all specimens that I have seen, there is a dark stripe on the 7th row anteriorly and on the 6th row posteriorly. In many specimens the stripes on the 3rd and 8th (posteriorly the 7th) scale-rows are absent or present so far posteriorly that the 8th row is never involved. The dark brown on the first scale-row and the presence of a lateral dark stripe on the 4th row of dorsal scales only, in combination with the characteristics of the genus, distinguish _C. l. lineatus_ from all other snakes in México. _Distribution._--Semi-arid habitats on the coastal plain of Veracruz, México, from Tecolutla to Lerdo de Tejada and Piedras Negras (fig. 2). _Specimens examined._--Total of 27, as follows: MÉXICO: _no specific locality_, AMNH 19614-15, 19621-24, 19642-43, NMW 16827. _Veracruz: no specific locality_, AMNH 19618-20, CAS 73640, NMW 16829; _4 km.
