I am doubtful if <strong>the</strong> typical race <strong>of</strong> this plover, for this<br />
form is not more than a subspecies, is ever found west <strong>of</strong> North<br />
Borneo. I have certainly, with one very doubtful exception,<br />
seen none from any part <strong>of</strong> <strong>the</strong> <strong>Malay</strong> Peninsula, all being<br />
referable to <strong>the</strong> present race which, as Sharpe points out, has<br />
a slightly longei tarsus.<br />

" Iris dark hazel, bill black, feet slate."<br />
Until Gyldenstolpe, Hoc. cit.) identified a pair <strong>of</strong> plovers<br />
obtained at Koh Lak in Peninsular Siam as this species I had<br />
hi<strong>the</strong>rto regarded our fairly considerable series as a tropical<br />
resident race <strong>of</strong> Ae. alexandrina, which indeed it is.<br />
Seven males from various part^ <strong>of</strong> <strong>the</strong> Peninsula have a<br />
wing <strong>of</strong> 93-99 mm. and eight females 93-100 mm.<br />
A eries from Borneo, <strong>the</strong> loan <strong>of</strong> which we owe to <strong>the</strong><br />
kindness <strong>of</strong> <strong>the</strong> Sarawak Museum authorities has <strong>the</strong> wing in<br />
four males 91-94 mm. and in three females (one very worn)<br />
88-94 mm. so 'hat <strong>the</strong> Peninsular race would appear to be<br />
slightly larger. In addition <strong>the</strong> Peninsular birds have <strong>the</strong><br />
dark loral streak much less strongly developed, while <strong>the</strong><br />
fea<strong>the</strong>rs <strong>of</strong> <strong>the</strong> mantle an somewhat paler with lighter<br />
edgings; <strong>the</strong> white at <strong>the</strong> base <strong>of</strong> <strong>the</strong> inner primaries is also<br />
more extensive. Material from Java and from Timor, which<br />
is probably <strong>the</strong> typical locality, is however required before <strong>the</strong><br />
mainland race can safely be separal
