616 ON THE GENERA AND SPECIES OF CYPSELIDZ. [June 27, 
2. O. leucopygia, from New Caledonia. 
3. C. linchi, from Java, Malacca, and the Nicobars. 
4. C. spodiopygia, from the Samoan and Fiji Islands, 
5. C. troglodytes, probably from the Philippines. 
6. C. fuciphaga, from ‘“ Bourbon and Mauritius (var. francica, 
Gm.) ; India and Ceylon ; the whole of the Malay Islands ; Louisiade 
Archipelago; New Caledonia; Tahiti (var. leucophea, Peale ; ct- 
nerea, Gm.); Marianne Islands.”’ 
Mr. Wallace states that the British Museum contains a seventh 
species, from the New Hebrides, as yet undescribed. 
Genus 4. DENDROCHELIDON. 
Macropteryx, Sw. Zool. Ill. (1832). 
Pallestre, Lesson, Compl. Buff. viii. p. 490 (1837). 
Dendrochelidon, Boie, Isis, 1844, p. 165. 
Chelidonia, Streubel, Isis, 1848, p. 370. 
This is likewise a purely Palzeogean form to the species of which 
I have paid little attention. Those I am acquainted with are the 
following :— 
1. DeENDROCHELIDON MYSTACEA. 
Cypselus mystaceus, Less. Ois. t. 22. 
Macropteryx mystaceus, Sw. 
Dendrochelidon mystaceus, Gould, B. Asia, pt. xi. pl. 5. 
Mr. Gould states that the habitat of this bird is the Aru Islands 
and New Guinea; but the truth is, its range is more extensive. 
The Leyden Museum contains specimens from Amboina, Ceram, 
Bouru, Morotai, Guebé, Batchian, Halmaheira, and Waigiou. 
2. DENDROCHELIDON WALLACII. 
Dendrochelidon wallacei, Gould, P. Z. 8. 1859, p. 100, et B. Asia, 
pt. xi. pl. 4. 
Hab. Celebes and Sula Islands (Mus. Lugd.). 
3. DENDROCHELIDON KLECHO, 
Hirundo klecho, Horsf. 
Dendrochelidon klecho, Gould, B. Asia, pt. xi. pl. 3. 
Hab. Java, Sumatra, and Malay peninsula ; Banca (Mus. Lugd.). 
The very remarkable mode of nidification of this Swift is described 
by Dr. Bernstein in the ‘ Journal fiir Ornithologie’ for 1859 (p. 183). 
Dr. Bernstein says that the nest resembles in form and materials 
that of Collocalia, but is still smaller and flatter! It is a semicir- 
cular structure, and is affixed to a small naked horizontal branch 
high up in a tree, the branch forming the flat side of the nest. The 
walls, scarcely thicker than parchment, are made of feathers, tree- 
mosses, and bits of bark, cemented together by the viscous saliva of 
the bird. The nest, which contains a single, perfectly oval, white egg, 
is so small that the bird (as repeatedly observed by Dr. Bernstein) 
sits upon the branch, and covers it with only the end of her belly.
