918 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 grey on the outer side and feet" (Australia — Gould 5). 

 Immature. Differs from the adult in having the chin, upper throat and cheeks white; the 



chestnut stripe on the head and neck imperfect (Kabruang, Nov. 1893 — C 13025). 

 Measurements (.'> adults from Talaut and 1 Sangi). Wing (over the arc) 100 — 112nmi, 



(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 wliich 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, Ramsay, etc. 1, III, 5, b 4, b 5, b 6); New 



Guinea (D'Albertis, Morton & Blunden 6'); Sangi Islands — Great Sangi (Nat. 



Coll. in Dresd. Mus.); Talaut Islands — Kabruang (Nat. Coll. do, 9); Java 



(Vorderman ci 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 will be found from Borneo to Tasmania. In Celebes, where P. tricolor 

 occurs, P. gularis is not yet known; on the other hand, P. tricolor has not been 

 sent to us from Sangi 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 brown, 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 lower 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.
