Show 572 MESSRS. SCLATER AND SALVIN [June 20, Coues, and are therefore S. antillarum as understood by that and fully described I. c. Besides its black point, the bill is shorter and not so deep as in 8. superciliaris. So far as we know, this species does not go further south than the West-Indian seas. 10. STERNA EXILIS. Sterna exilis, Tsch. F. P. Aves, p. 306; Sclat. P. Z. S. 1867, p. 336 et p. 344. Sterna lorata, Ph. et Landb. Wiegm. Arch. 1863, pt. 1, p. 124. Hab. Coast of Peru, near Lima (Nation) ; Arica (Frobeen) ; coast of Chili (Mus. Brit.). Sclater has already expressed his doubts as to whether S. exilis of Tschudi is really applicable to the present species. Tschudi's description is manifestly taken from a young bird ; and all that can be said is that it is more probably applicable to this species than to any other. There can be no doubt that this Tern is the £. lorata of Messrs. Philippi and Landbeck, as their description accords in every respect with our specimen from Lima. Genus 5. GELOCHELIDON, Brehm. 1.
