Herein, we report the first observation of two different coloration patterns in Chilean snakes. Based on the alteration of wild coloration patterns, a juvenile specimen of Tachymenis chilensis coronellina Werner, 1898 was diagnosed with albinism and a juvenile specimen of Tachymenis chilensis chilensis (Schlegel, 1837) was diagnosed with leucism. The existence of color variations in wild snake populations and the implications of these for fitness are discussed.

在此，我们报告了对智利蛇两种不同颜色模式的首次观察。根据野生着色模式的改变，1898 年的智利速食草幼体被诊断为白化病，智利速食者的幼年标本 (Schlegel, 1837) 被诊断为白化病。讨论了野生蛇种群颜色变化的存在及其对健康的影响。
