foreheads, black crowns and hiiid-,iiiescks, grey upper and white 
lower siu iaces. About two i>er cent, of the llock will 1)e " Black 
Terns," (which I take to be H. iu(jra), about the same size as 
the others, Init gl'ey above and below and with black heads and 
faces. Both these have practically square tails and black beaks ind 
leg's. The remainder, some thirty per cent, of the whole, are much 
larger and have deeply forked tails. Their beaks and legs aro 
are red, their wing's a lovely French-grey, and the rest of the body 
pure wliite. These, which are also the commonest Tern to be seen 
along the Ijcach in Bathurst, must, I think, he SHcrn,% fluviaiilis,, 
while the other two with square tails must belong to the gienus, 
Hifdrochclidon, and are prohably //. hy'rida and nigra in young* 
or non-lireeding plumagie. On the river's five mile broad estuary 
and for some fifty miles up, a fourth species, a larger and more 
heavily built Tern is common. This in full plumage is grey above, 
and white below, hut mottled with brownish when young; it has 
the foreliead white, the top of the head grey, and the hinder part 
of the crown black and h'eariuig la slight crest. The biil yellow, and, 
tho legs black with olive-yellow plantar surfaces to the toes. These 
I take to be .S'. vwxima or jiossihly. cnspia, though from somei 1 
shot at AUireda, in June, 1907, I iaft-line to the first diagnosis, las 
on all of them a white line down the inner wiebs of the primaries 
was very mai'ked. Prohably both species occur here. These Terns 
are very stiong on the wing, and fly backwards and forwards at some 
height above the water, at which their yellow beaks are always 
pointing vertically downwards at right an(gles to their course, and 
into which they frequently hurl themselves headlong after their finnj'- 
prey. Both gulls and Terns are all known here by the general 
names BATANANA (sea-swallow) in Mandingo, and DOR in Joloff.
