摘要

Two preserved museum specimens of the colubrid snake, Oligodon formosanus, possessed both collapsed and uncollapsed small reptilian eggs in their digestive tracts. This suggests that the species, previously known to slit the shell of a reptilian egg and ingest the insides , occasionally swallow small eggs whole with or without slitting the shell. Nutritional significance in the shell-cutting by the reptile-egg eating snakes is brie fly discussed.

檢視博物館內保存的兩條赤背松柏根（Oligodon formosanus），消化道內含有完整及破裂的小型爬蟲類的蛋。由此印證了本種蛇類會劃破爬蟲類的蛋殼以攝取內合物，但偶而也會整個吞下而沒有有弄破蛋殼的記錄。本文並且簡短的描述了劃破蛋殼的動作對攝食爬蟲蛋的蛇在營養攝取上的重要意義。
