and black dress of the juvenal stage, already well described. In the 

 next stage (represented by No. 9,339, Don Diego) the bird resembles 

 the adult in general, but the markings of the upper parts and neck 

 are coarser, and the lower breast and tibiae are more or less conspicu- 

 ously barred with black and buffy. It was an individual in this stage, 

 apparently, to which Mr. Ridgway gave the name Tigrisoma excellens 

 {Proceedings U. S. National Museum, X, "1887," 1888, 595). Fi- 

 nally, there is the fully adult bird, fitting the published descriptions. 



This species is found in the Tropical Zone of this region, from sea- 

 . level up to 3,000 feet, but is confined to the forest along the streams. 

 It is most numerous along the Cienaga Grande, in the mangroves and 

 inundated forest, but is rare in the hills.

One specimen: La Tigrera. 



Simons secured an adult of this tiger bittern at Minca on January 

 22, 1879, but when he speaks of the abundance of the bird on the 

 Magdalena River he probably refers to the other species, T. lineatum, 

 which seems to be more of a lowland form than T. salmoni. The only 

 specimen secured by the writer was shot at La Tigrera, May 10, 1913. 

 Mr. Smith's collector secured a single immature example at Valparaiso 

 (Cincinnati) in April, 1899. An individual was seen here also by the 

 writer in March, 1914, and another at Las Taguas (at 5,000 feet) in 

 June, 1919. They were on boulders in swift mountain streams running 

 through dense forest.

Seven specimens : Bonda and Mamatoco. 



A flock of about a dozen Black-crowned Night Herons was met with 

 in the marshes near the village of Mamatoco on May 22 and 23 and 

 August I and. 2, 191 3, when adults and young were secured. Mr. 

 Smith sent in two adults from Bonda, May i and. June 10, 1899. No. 

 42,612, a young bird in juvenal plumage (August 2) cannot be matched 

 in a considerable series, its back being much more deeply rufescent.
