Birds of Celebes: Psittacidae. 
2. Tanygnathus megalorhynchus sumbensis (Meyer). 
f. Tanygnathus megalorhynchus var. sumbensis (1) Meyer, Verb. z.-b. G-es. Wien 1881, 
XXI, 762. 
g. Tanygnathus megalorhynchus (1) Salvaclori, Cat. B. XX, 1891, 428 footnote. 
h. Tanygnathus megalorhynchus sumbensis (1) Hartert, Xov. Zool. 1896, 588. 
Diagnosis. Under wing-coverts greenish yellow, instead of deep yellow; under surface greener 
than in the typical form. , 
Distribution. Sumba (Eiedel f 1, Doherty h i). 
3. Tanygnathus megalorhynchus — sumbensis. 
i. Tanygnathus megalorhynchus (1) Hartert, Xov. Zool. 1896, 176. 
Diagnosis. Intermediate (C 15857 — 58). 
Distribution. Djainpea Island (Everett). 
Observation. Mi’. Hartert [h 1] considers these specimens more like the typical form, we 
more like sumbensis-, probably an intermediate position will not be far wrong. 
The first notice of the occurence of this Parrot in Celebes was made in 1821 
by Rein war dt, who simply mentions that Psittacus ornatus, Ps. macrorhynchos 
(i. e. meyalorhynchiis) and Ps. leucorhynchus were the three species of Parrot met 
with by him at Lake Tondano, hut he may have perhaps misnamed the red-billed 
muelleri: macrorhynchos. In 1871 it was found by Meyer on Mantehage, a 
small' island north of Mauado about 8 V 2 miles off the coast, — not in the Togian 
Islands as stated by Count Salvador! (d 12). Again in 1879 two specimens 
were sent to the Dresden Museum from van Musschenbroek with the locality 
“Menado” attached in that gentleman’s writing. In the Sangi Islands the species 
abounds (d 5)-, it is also, according to Dr. Hickson, not uncommon in the Ta- 
laut Islands. As was remarked by Meyer in 1879, T. megalorhynchus appears 
to be a species which is extending its range. 
The Sumba birds have all greenish yellow under wing-coverts, instead of 
deep yellow, by which means the two forms may most readily be distinguished; 
also the under surface is greener — not so decidedly yellow-green, as in speci- 
mens of the typical form. Seen from above the two forms are not to be 
distinguished. 
T. megalorhynchus with its allies, T. afjinis (Ceram group) and suhaffinis 
(Timorlaut) forms a very well marked section of the genus Tanygnathus, with 
great bloated-looking red bills, inhabiting the Moluccas, some of the Pajju-an 
Islands, etc. T. megalorhynchus with its blue wings and strongly contrasted colours 
on the wing-coverts appears to be the most highly differentiated form of the 
three. The connection of this section with the other members of the genus 
appears to be tbrough T. affinis of Buru etc. and T. luconensis of the Philijjpines. 
T. luconensis, though much smaller, has like the megalorhynchus group its bill 
red in both sexes and in the young (upper mandible red, lower orange in adult, 
according to Salvadori), and the coloration of the Avings shows much similarity 
to T. affinis -, the head of the adult T. luconensis is, however, blue or g-reyish
