Stokes' Sea Serpent. Hydrus stokesii.
REPTILES. PLATE 3.
Grey; white beneath; scales of the back, broad, ovate, cordate, keeled; of the sides larger, and of the belly largest, all keeled; of the two central series of the belly rather larger, more acute and smooth. Labial shields, 5, 1, 5, high band-like; the 4 and 5 the highest. 1, cheek scale; 1, anterior, and 3, posterior ocular, the lower hinder largest; the hinder labial shields behind the eye small, the hinder one smallest.
Inhabits Australian Seas.
This species is the giant of the genus, being very many times larger than the Hydrus major of Shaw (Pelamis shawi, Messem.) from the coast of India. The body is as thick as a man's thigh, and it must have been a most powerful and dangerous enemy to any person in the water.
