Small “Honey-eaters” (? Sun birds) with very long slender curved bills, long 
wings, long square tail, and short legs and small feet. The bill is gently curved, 
almost twice as long as the head, very slender and anteriorly attenuate while 
basally there is little expansion ; the culmen is scarcely keeled at its base and 
is rounded towards the delicate top, while the edges of the upper mandible seem 
to curve inwards and clasp the lower one, which is very slender, w ith the inter- 
ramal space ill defined and scarcely feathered, and the whole is decurved in 
agreement with the upper; the nasal groove is indistinctly separated, about 
one-sixth the length of the mandible, the operculum strong, the nostrils 
appearing as a long linear slit; nasal bristles prominent, but rictal bristles 
short and not very noticeable. 
The wing has the first primary short, about half the length of the second, 
which is about equal to the eighth and longer than the secondaries ; the third 
is longer than the seventh, the fourth, fifth and sixth subequal and longest. 
The tail is long and square, even slightly emarginate. 
The legs are short and obscurely scutellate in front, six scutes counted in 
the hnmature, but the adult appearing almost booted, bilaminate posteriorly. 
The toes are slender, the hind-toe and claw stouter, the middle toe and claw 
longest; the outer longer than the inner, and the claw rather long and slender. 
When the “ Honey-eaters ” of the Australasian Region are anatomically 
studied many of the puzzles will be elucidated, but the name seems bad when 
it is realised that the “ brush tongue ” is not for honey-eating, but minute 
insect catching, honey being a secondary article of food.
