oval and blunt at both ends, 2g inches long, and about 1 inch 
through in the thickest part, chalky-white in colour, marked 
somewhat sparingly with underlying ash-grey, and overlying 
sienna. A living young bird from the nest was brought to me, 
but soon died. — H. N. R.~\ 
5. Gygis Candida ( Gm .) ; Sharpe, t. c. p. 465. 
One adult and two young birds. The latter are white like 
the old birds, but have much smaller bills. 
[This is a common bird in many parts of the island, nesting 
in trees, especially those of the Sapate, where there is a colony 
near that of the Anous. The bird is called “Viuva bianca.” —

Of this Tropic-bird two specimens were procured. It is 
common on the island, nesting on the Peak and on other rocks 
and cliffs. An egg was obtained on St. Michael’s Mount. The 
birds were taken in snares by the convicts. 
7. Sul a leucogastea. 
An adult and a young bird. This species of Gfannet, known 
as “ Mbebu,” is a common bird, nesting on cliffs on all the 
islands. The young are pure white. 
Besides these birds we saw several of which no specimens 
were procured. Tacliypetes a pail a was abundant, nesting on St. 
Michael’s Mount, and a small species of Albatros appeared several 
times round the island, but kept well out of gun-shot. Three 
species of Waders were seen : — One, a small Plover, of which we 
twice saw a flock at San Antonio Bay, and once or twice single 
birds flying along the coral-reefs ; a bird resembling a Yellow- 
shank, grey and white, of which a pair appeared at San Antonio 
at the end of our visit ; and a single specimen of a Sandpiper, at 
the same spot and time. These wading birds were all very shy, 
in marked contrast to the endemic species, which suggested that 
they were migrants, and had come from the mainland, where they 
are more cautious at the sight of man. The last two species 
appeared on the same day towards the end of our visit, which 
confirmed the view that they were migrating.
