The Adventure of the Speckled Band 1

"“It is a swamp adder!” cried Holmes; “the deadliest snake in India...."   (The Adventure of the Speckled Band)

Cursory research indicates that no such snake exists. Not only is the “swamp adder” an invented species, there are no adders native to India. Herpetologists have suggested that the species that most closely resembled Doyle’s snake is the Indian Cobra, which is adequately speckled and releases a fast-acting neurotoxin. It is unclear whether Doyle was mistaken or chose to have Holmes misidentify the snake.
