137.  XEMA JAMESONII.—­Jameson’s Gull.

This bird was seen only on Cooper’s Creek in lat. 27 degrees, long. 102 degrees; where three or four were sitting on some rocks in the middle of the water, and far out of gun’s reach.  They appeared to be similar to the English gull, with a slate-coloured back and wings, and white breast.  On firing a shot, they rose and followed the ducks which rose at the same time up the creek, and when flying they seemed exactly to resemble the common gull.  The only swan we saw was on this sheet of water, with eight or ten cormorants.

138.  HYDROCHEDIDON FLUVIATILIS, Gould.—­The Marsh Tern.

The only specimen seen during the Expedition, was shot by Mr. Stuart on Strzelecki’s Creek.  It was flying up and down the creek, plunging into the water every now and then.  This light and airy bird had a slate-coloured back, with black neck and breast; the crown of the head was black, delicately spotted white.

139.  PHALACROCORAX SULCIROSTRIS.—­Groove-billed Cormorant.

Of a fine dark glossy green plumage; common on all the creeks and rivers of the interior.  These birds were very numerous at the Depot, and were constantly coming in from, and flying to the N.W.  But although we afterwards penetrated some hundreds of miles in that direction, we never discovered any waters to which they might have gone.

140.  PELECANUS CONSPICILLATUS, TEMM.—­The Pelican.

Like the swans, these birds frequently passed over us, coming from, and going to that point to which all the aquatic, as well as many of the ordinary birds winged their way.  We sometimes saw them low down, sweeping over the ground in circles, as if they had just risen from the water; but in neither instance could such have been the case.  On several occasions we might have shot them, but they were useless, and would have encumbered us much.

141.  PODICEPS GULARIS.—­Grebe.

The common Diver; frequenting the pools and rivers of the interior:  of dark brown plumage and silver-white belly.  There are two or three varieties of this bird, that I have seen on other occasions; but none, with the exception of the present specimen, during the recent Expedition.
