Carriker : List of the Birds of Costa Rica. 433 



feet, and in a few instances it has been taken even higher than that. It 

 seems to be resident wherever found, but I have never seen the nest. 

 Habits identical with those of the species in North America. 



101. Tigrisoma lineatum (Boddaert). 



Ardea lineatum Boddaert, Tabl. PL Enl., 1783, 52. 



Tigrisoma lineatum Sharpe, Cat. Birds Brit. Mus., XXVI, 1898, 195. — Salvin 



and Godman, Biol. Centr.-Am., Aves, III, 1901, 178 (Panama, southward). 

 Tigrisoma excellent R IDG WAY, Proc. U. S. Nat. Mus., X, 1887, 595 (type from 



Rio Segovia, Honduras, taken also in Talamanca [Jose Zeledon]). 



Carnegie Museum: El Hogar, Aug. 23, T906 — immature £ (Car- 

 riker). 



In the collection of the Carnegie Museum is a good 'series of skins of 

 T. lineatum, both adults and young, from Colombia. When these 

 specimens were carefully compared with Mr. Ridgway's description of 

 T. excellens, no differences could be detected, and it therefore seems 

 to me that T. excellens should be placed under the synonymy of the 

 present species. The single immature female taken at El Hogar is 

 identical with Colombian specimens in the same stage of plumage. 

 This bird was shot from a tree beside a small stream in the forest. 



102. Heterocnus cabanisi (Heine). 



Tigrisoma cabanisi Heine, Jour. fiirOrn., 1859, 407. — Lawrence, Ann. Lye. 

 N. Y. , IX, 1868, 142 (San Carlos [J. Carmiol]). — Frantzius, Jour, fiir 

 Orn., 1869, 376 (Rio Macho). — Nutting, Proc. U. S. Nat. Mus., V, 1882, 

 406 (La Palmade Nicoya). — Cherrie, Expl. Zool. en C. R., 1891-2, 1893, 

 52 (Boca Mala). — Underwood, Ibis, 1896, 450 (Miravalles). — Salvin 

 and Godman, Biol. Centr.-Am., Aves, III, 1901, 179. 



Heterornus cabanisi Sharpe, Cat. Birds Brit. Mus., XXVI, 1898, 198 (Costa 

 Rica [Carmiol]). 



Carnegie Museum: Guapiles, Miravalles, Coronado de Terraba (Car- 

 riker). Five skins. 



Restricted almost entirely to the lowlands of both coasts, up to about 

 1,200 feet. Frantzius records the taking of a specimen at the Rio 

 Macho which has an altitude of about 3,000 feet. If the bird was actu- 

 ally taken there (which I doubt) it is a very unusual occurrence. 

 They appear to be more abundant on the Pacific coast, are always met 

 with (during the day) in the trees along the edges of rivers and 

 lagoons, and are quite solitary in their habits. I found them particu- 

 larly abundant along the lower portion of the Rio Grande de Terraba, 

 especially in the delta.
