Genus SPHENOCERCUS

This genus much resembles Osmotreron in Coloration, but is distinguished by having a much longer and graduated tail, and by wanting the sinuation on the inner web of the third primary. The under tail-coverts are as long as the outer tail-feathers or longer. The rhamphotheca, or hard horny part of the bill, is shorter than the soft basal portion.

Eight species are enumerated in Salvadori's Catalogue ; of these two are Himalayan and Burmese, the others range through the greater part of the Oriental region east of India.

Key to the Species.

Middle tail-feathers acuminate and extending generally 2 to 3 in. beyond the next pair………………………S. apicicauda, p. 16.
Middle tail-feathers not acuminate, extending very little beyond next pair………………………S. sphenurus, p. 16.
