Dave 1942 Spilotes Lake Omega, Zoo; Ref: S. San Miguel, El Salvador Feb. 15, 1942. Scales of tail much clouded with black, forming definite black interfaces, alternating with rings of fine yellow, or slightly black- speckled yellow scales, the yellow rings showing up much more distinctly on the tail. Under- side of tail yellow, with much clouding of black on most of the scales, there being more clouding on the median sutures, forming a zig-zag black streak medially; interrupted over most of its length by absence of such black on the median sutures. Dorsal scales white at base, or with base lighter yellow than rest of scales. Feb. 16, 1942. Saw 2 more today, both in the dense jungle, but could not get a shot at either. This makes 4 seen or collected in two days. It seems odd that they should not have been seen until yesterday.
