Lake Omega, Zoo; left to San Miguel, El Salvador Feb. 15, 1942. Are two names indicate two well-marked phases. A brief description of color follows: 1255 - Snout & sides of head yellow, with black sutures. Top of head black. Anterior 1/2 of body variegated with yellow, but with no definite stripe. There are eleven definite yellow stripes over the posterior 1/2 of the body, the first 5 about 20-25 mm. in width, the last 6 about 15 mm. The scales between the stripes are irregularly speckled & blotched with yellow. The tail has 14 yellow annuli, some of them incomplete. The gastrosteges have black laterally, although this is lacking in some. Most of them have a median path of black. Otherwise the underparts are yellow. The tail is primarily black underneath, with large splotches of yellow. Scales above are black at the base, & beeked, except for the row above the gastrosteges. 1251 - Head so badly mutilated to see anything. Body color primarily yellow, but point of scale edged with black. Over posterior 1/2 of body there are rings of pure yellow scales alternating with interspaces of black-tipped scales, thus showing a faint resemblance to the striping of yellow on black of the other specimen. Under-side pure yellow with no black of any kind.
