SqUATAROLA HELVETICA. 
Many observed near Husum feeding on a tidal marsh and 
mudbanks of the creek, mostly in pairs. A few seen on 
Sylt. 
iEGIALITIS HIATICULA. 
Common on Sudfall, but not so numerous as the next 
species, which is found all over the island, while this only 
frequents the sea-beach. On Sylt JEgialitis hiaticula was 
more numerous than JE. alexandrina; and on Amrum the 
proportion was about one to three. On the coast at Husum 
we reckoned the proportion of AS. hiaticula to JE. alexandrina 
at about one to ten. At Hoyer, the most northern point of 
the mainland we visited, the former was numerous; and we 
did not see AS. alexandrina there, probably owing to the 
nature of the ground, which was clothed with a scanty vege¬ 
tation. To sum up, JE. hiaticula is found more especially on 
shingle and where the vegetation is slight, as it often prefers 
nesting amongst a few blades of grass. It is much more de¬ 
monstrative when its nesting-ground is invaded than AS. alex¬ 
andrina ; and its note is much stronger than that bird's. 
iEGIALITIS ALEXANDRINA. 
Many observations on this species would only be a repetition 
of those on the preceding. We never saw it where there was 
any vegetation, as it prefers the most barren spots. The nests 
were generally on fine shingle or gravel in the most exposed 
places. On Sudfall we found a nest amongst clods of earth 
on the marsh, lined with a few fragments of roots of grass. 
Its note is much weaker than that of JE. hiaticula; and it 
never flies round one on approaching its nest, but contents 
itself with feigning lameness, or flying a short distance and 
then pitching again and running on in front of the observer, 
uttering a feeble whistle— twee, twee } twee. It appears a 
much more slender bird than JE. hiaticula , and, when flying, 
of a lighter colour on the back ; when standing on the ground 
and facing one, the two patches of black, one on each side of 
the breast, are very conspicuous. The nest seemed to be 
somewhat smaller than that of the other species ; it is
