Schlumberger and Lucki — Tumors in Fishes 



707 



The last of the snake tumors on record is a papil- 

 lary carcinoma of the bile duct in an East Indian 

 watersnake Homalopsis buccata. It was the only 

 tumor found by Bergman in 2200 wild snakes ex- 

 amined (11). He suggests that the apparent rarity 

 of neoplasms in wild snakes may be attributed to the 

 fact that a tumor-bearing individual living under 

 natural conditions would probably be so handi- 

 capped that it would fall an easy prey to its enemies. 

 The tumor was a small mass which projected into the 

 lumen of the duct, partly occluding it and infiltrating 

 the wall and the neighboring tissues. Histologically 

 it consisted of atypical pleomorphic epithelial cells. 

 It is of interest that a trematode was found in close 

 proximity to this tumor, because in the gall bladders 

 of other reptiles, green turtles, trematodes have been 

 found associated with papillomatous growths (193).
