 Scarus pavonius Gronow, Cat. Fish, ed. Gray, 1854, 63 (Surinam). 

 Crenicichla frenata Gill, Ann. Lye. Nat. Hist. N. Y., VI, 1858, 386 (Trinidad). 

 Crenicichla saxatilis albopunctata Pellegrin, "Cichlides," 338, in Mem. Soc. Zool 



France, XVI, 1903, 374 (French and British Guiana). 

 Crenicichla vaillanti Pellegrin, Bull. Mus. d'Hist. Nat., IX, 1903, 124; "Cich- 

 lides," 304, in Mem. Soc. Zool. France, XVI, 1903, 340 (Mana; British Guiana). 

 I secured two forms of Crenicichla resembling saxatilis. One is found along 

 the coast and inland to Rockstone, the other from Rockstone on upward. I never 

 secured both forms together except on Gluck Island at Rockstone, at the boundary 

 between the two areas. The coastal form is undoubtedly the saxatilis of Bloch 

 (of which I examined the originals in Berlin) and also of authors generally. 



The upper one may be one of the nominal Amazonian species. It will require 

 a larger series of Amazonian specimens than there are on hand at present to deter- 

 mine whether the Amazonian forms are all saxatilis, or whether one of them is the 

 species found in the upland of Guiana. I therefore give only that part of the 

 synonymy and bibliography which undoubtedly refers to saxatilis, and pro- 

 visionally describe the upland species as new.
