estimated 300-500 birds circled over the shore northeast of Tawau.

_=Ardea sumatrana sumatrana=_ Raffles: Dusky-gray Heron.--_Specimens_,
2. Karindingen Island: [Male] testis 12 x 23 mm., November 24, 1962, MCT
3308; [Male], November 24, 1962, MCT 3309.

The specimens were taken on the coral sand beach surrounding
Karindingen Island. At least 10 were seen feeding on the beach and
on a reef. One (MCT 3308) had testes of a size suggesting that it
was in breeding condition.

_=Casmerodius alba modestus=_ (Gray): Common Egret.--_Specimen_, 1.
Karindingen Island: [Female], November 24, 1962, MCT 3310.

This species was seen on three dates: August 17 at Karindingen
Island, where 30 were observed feeding along the mangroves
bordering the island; on November 24, on the same island, where a
specimen was taken from a flock of 30 birds that had been feeding
on the coral sand and reef; and on November 30 when a single bird
landed at the small reservoir at the Cocoa Research Station and
began to feed in the shallow water. Only four specimens appear to
have been recorded earlier (Smythies, 1957:561), although Smythies
(1963:270) lists additional sight records.

_=Egretta garzetta=_ (Linnaeus): Little Egret.--On November 24 at
Karindingen Island, I observed several mixing freely with individuals of
_E. sacra_ on the coral sand beaches and reefs.

_=Egretta eulophotes=_ (Swinhoe): Chinese Egret.--_Specimen_, 1:
Ka-Karis, Kinabatangan River, 200 feet: [Male], October 20, 1963, ADG
326.

This is the only record known to me of this species from North
Borneo. Smythies (1960:126) lists 11 specimens from other parts of
Borneo.

_=Egretta sacra=_ (Gmelin): Reef Egret.--The species was observed at
Karindingen Island on August 17 and November 24, 1962, and was the most
common egret on the island. One compact flock of 50 was seen at high
tide. No white-phased birds were in the flock.

_=Bubulcus ibis coromandus=_ (Boddaert): Cattle Egret.--_Specimen_, 1:
Tongod: [Female], October 21, 1963, ADG 328.

Individuals were observed daily at Tuaran with cattle at the
Agricultural Research Centre. I saw them on December 9 when I
arrived at Tuaran and again on January 13, when I departed.

_=Ardeola bacchus=_ (Bonaparte): Chinese Pond Heron.--_Specimen_, 1: 12
mi. N Kalabakan: [Female], October 26, 1962, MCT 3151.

The specimen was brought
