Birds of Celebes: Podicipedidae. 
of the feathers white on the jugulum; sides and flanks browner; lower breast and 
abdomen silky white (ad., Kabruang, Talaut Is., Nov. 1893: Nat. Coll. C 13024. 
“Bill greenish grey, with a light ash-coloured spot at the extreme tip of the 
upper mandible; sides of the upper mandible from the tip to near the nostrils, and 
the tip of the lower mandible bluish grey ; base of both mandibles yellowish grey , 
gape primrose-yellow; irides lemon-yellow; inner side of the tarsi yellowish grey, passing 
into greenish gi-ey on the outer side and feet” (Australia — Gould 5). 
Immature. Differs from the adult in havhig the chin, upper throat and cheeks white; the 
chestnut stripe on the head and neck hnperfect (Kabruang, Nov. 1893 — 0 13025). 
Measurements (5 adults from Talaut and 1 Sangi). Wing (over the arc) 100-11 2 mm, 
^straight) ca. 94—104; tarsus ca. 34; middle toe with claw ca. 50; exposed culmen 
18 — 22 mm. 
Eggs. 5, occasionally 6; bluish white when first laid, thinly coated with lime, but quickly 
becoming soiled with the wet and decaying weeds of which the nest is formed 
(North b 6'). 
Nest. Of sedges and other aquatic herbage, attached to a few reeds in the water (North b 6). 
Distribution. Australia and Tasmania (Gould, Bamsay, etc. 1, HI, 5, h 4, b 5, b 6); New 
Guinea (D’Albertis, Morton & Blunden d); Sangi Islands — Great Sangi (Nat. 
Coll, in Dresd. Mus.); Talaut Islands — Kabruang (Nat. Coll, do, 9); Java 
(Vorderman d 1]; ? Borneo (Vorderman d 3, d 4). 
Until quite recently this little Grebe was known only from Australia and 
New Guinea, but in August, 1893, a specimen was sent to the Dresden Museum 
from Great Sangi, to be followed by a nice series shot in November the same 
year on Kabruang in the Talaut Islands. It was not included in two sub- 
sequent collections from that group. Previously to this Dr. Vorderman had 
described a bird from Java as P. tricolor, which is, however, obviously the present 
species; and we suppose his subsequent record under this name of a bird from 
Banjermassing, Borneo, must be P. gularis also. If so, it is probable that 
P. gularis Avill be found from Borneo to Tasmania. In Celebes, where P tricolor 
occurs, P. gularis is not yet knowm; on the other hand, P. tricolor has not been 
sent to us from vSangi and Talaut, though P. gularis appears to be plentiful in 
the latter group. 
This species is easily distinguishable from P. tricolor by its black chin, 
cheeks and upper throat, by a stripe, simply, of chestnut on the head and neck, 
by its white secondaries with only the part of the outer webs exposed on the 
closed wing browm, by its shorter bill, and its white belly. It has nearer affinities 
with P. minor, the Little Grebe of Europe, Africa and Asia, which has, how- 
ever, the fore neck (except the low^er part), the ear-coverts and sides of neck 
chestnut, as compared with the chestnut stripe starting narrowly from the corner 
of the eye and widening on the sides of the neck in the Australian or Black- 
throated Little Grebe, Podiceps gularis.
