294 ORNITHOLOGY. 



NIGHT-HERON. 



In the dark silent night the voyager is often startled by 

 the dolorous scream of the night-heron along the shores, 

 whose loud roar so much resembles the bellowing of a 

 cow, that the Burmese call it the " cow-bird," which re- 

 minds us of the " bull-of-the-bog," one of the names of 

 the bittern.

OTHER HERONS. 



There are other herons on the Coast which I have not 

 identified. Capt. Phayre found the following in Arracan. 

 Ardea malaccensis. 



Ardea purpurea. 



Ardea schist acta t {large, slate colour.) 



" fusca. (broivn.) 



u ardeziaca, (small, slate colour.)

Nycticorar* griseus (night-heron.) 



DEMI-EGRET. 



A demi-egret is met with in Arracan, but I have never 

 seen it in these Provinces. " Colour," says Mr. Blyth, 

 " uniform dark slaty throughout; some specimens having 

 a white line on the chin and throat. Adults have narrow 

 lengthened plumes on the back and breast, similar to those 

 of Ardea cinerea: the occipital plumes also are somewhat 

 lengthened, as in herons generally; but I have seen no 

 defined occipital crest, and doubt its ever possessing one. 

 Beak mingled dusky, and dull yellowish, and the legs ap- 

 pear to have been olive-green." 

 Demigretta concolor. 



Nyctiardea, Swainscn.
