The Key to Scientific Names
(Apodidae; † Cassin's Spine-tail Swift N. cassini) Gr. νεος neos new; L. Afra African; genus Apus Scopoli, 1777, swift; "The second, C. cassini, differs entirely in coloration, being black above with a smoky throat, white upper tail-coverts and abdomen white, the shafts of the feathers dark. Structurally, it has very long wings with a very short tail with stiff short spines. The tail is less than one-fifth the length of the wings. No close relationship between this and the preceding group is apparent, and I here introduce for it the new name NEAFRAPUS which may, as above, be considered of generic value. Type Neafrapus cassini (Sclater)." (Mathews 1918); "Neafrapus Mathews, Bds. Australia, vii, p. 264, 1918. Type by original designation, Chætura cassini P. Scl." (W. Sclater, 1924, Syst. Av. Aethiop., I, p. 263) (see Alterapus and Telacanthura).
