Family HYBRIDAE.

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.

GONIONOTUS, Gray.

Head ovate, depressed, covered with small rather acute scales, with 2 small frontal plates just over the rostral in front; rostral small, triangular, concave in the centre.  Nostrils large, rather anterior, in the middle of a rather large plate, with a slight slit to the hinder edge; labial scales rather larger; the lower ones with a concavity in the middle of each scale.  Eyes convex, rather large, pupil oblong; throat with small acute scales.  Body elongate, compressed, subpentangular; back covered with very small semicircular scales, with a row of larger ovate keeled scales on each side, and 2 or 3 rows of similar larger keeled scales over the vertebral line; the sides covered with moderate ovate keeled scales, rather larger beneath the belly, covered with a series of transverse rounded plates.  Tail elongate, rather compressed, subpentangular, tapering, like the back above, and with a single series of rounded transverse plates beneath.

Gonionotus plumbeus.

REPTILES.  PLATE 4.

Bluish-grey, belly and beneath white.  Length of body 9, of tail 4, total 13 inches.

Inhabits —­

This animal is at once known from all the other Homalopsina, by the three keels on the back, by having only a single series of plates beneath, and in the lower labial shields being pitted.
