(syn. Todiramphus Ϯ Beach Kingfisher T. saurophagus) Gr. λευκος leukos white; genus Halcyon Swainson, 1821, kingfisher; "The Sauropatis series is characterised by the diastataxic condition of the wing. ... Halcyon saurophaga Gould is of this affinity, but its white head, large size, and huge bill indicate that it deserves subgeneric separation, and I therefore introduce for it and its allies the new subgeneric name LEUCALCYON. The wing-formula is not very dissimilar, the first primary being longer than the fifth, the second longer than the fourth, the third longest.. The long strong bill is almost half the length of the wing, a ratio not approached in any of the smaller species." (Mathews 1918).
