ever seen. The ground color of Nos. 1, 2, and 3 is light sea green, almost 
malachite-green. The markings are large and irregular in shape, more 
properly called blotches. No. 1. The markings are numerous and 
evenly distributed over the entire surface, except a large blotch at the 
larger end, crescentic in shape and measuring about .80 in length. These 
markings are of clove-brown, with smaller markings of olive-green or 
olive-brown. No. 2. Similar to No. 1, but the blotches are not so large, 
yet almost blending in one large blotch at larger end. There are some 
longitudinal markings resembling pencil lines, of a li£ht olive. No. 3. 
Same as the above with the addition of a circular blotch, .45 in diameter, 
at larger end. The pencil-like markings are more numerous than on No 
2. No. 4. Sage-green, sprinkled sparsely with small blotches of olive- 
green, underlying this are spots and blotches of cinereous, more numerous
