 ever seen. The ground color of Nos. i, 2, and 3 is light sea green, almost 

 malachite-green. The markings are large and irregular in shape, more 

 properly called blotches. No. i. 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. i, 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 light 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.
