[47] FLOUNDERS AND SOLES. 271 



Habitat. — West Indian fauua. Key West to Rio Janeiro. 



We have found in the Museum of Comparative Zoology specimens 

 purporting to be the types of Hemirliombus ocellatus Poey (No. 11144 ; 

 Poey's number, 88). These are female specimens, and they differ from 

 the types of Hemirliombus cethalion, also from Cuba, only in their greater 

 size. 



Numerous specimens (11373) from Rio Janeiro belong to the same 

 species. Among these are males, which have the interorbital space 

 much broader than in the types of ocellatus and cethalion. Besides 

 these specimens, we have examined others from Hayti, Cuba, and Key 

 West, and there can be no reasonable doubt of their identity, and that 

 all are identical with Giinther's Hemirliombus aramaca. 



This fish is described and fairly well figured by Rauzaui under the 

 name of Syacium micrurum. It is the type of his genus Syacium, a 

 generic name which, strangely enough, has received no notice from 

 subsequent authors until the present time. 



48. SYACIUM LATIFRONS. 



Citharichthys latifrons Jordan and Gilbert, Bull. U. S. Fish Comm., 1881, 334. (Pan- 

 ama. ) 



Habitat. — Pacific coast of tropical America. Panama. 



This species is known only from the original types, taken by Pro- 

 fessor Gilbert at Panama. The several variations in this species have 

 not been studied. 



49. SYACIUM OVALE. 



Hemirliombus oralis Giinther, Proc. Zool. Soc, 1864, p. 154. Giinther, Fish. Central 

 America, p. 472, 1869, plate lxxx, fig. 1. (Panama.) Jordan & Gilbert, 

 Bull. U. S. Fish Com., 1882, p. 108-111. (Mazatlan; Panama.) 



Citharichthys oralis Jordan, Proc. U. S. Nat. Mus., 1885; 391. (Mazatlan ; Panama.) 



Habitat. — Pacific coast of tropical America : Mazatlan to Panama. 



This well-marked species has been well figured by Dr. Giinther, from 

 whose account our analysis has been taken. Numerous specimens have 

 been collected at Mazatlan and Panama by Dr. Gilbert. The sexual 

 changes in this species have not been reported. 



Genus XX.— AZEVIA. 



Azevia Jordan (genus novum). (Panamensis.) 



Type : Citharichthys panamensis Steindachner. 



This genus is proposed to include a single species hitherto referred to 

 Citharichthys, but distinguished by its tubercular gill-rakers, as also by 

 its small, firm scales, and other characters of minor importance. 



A second species of this genus was obtained by Professor Gilbert at 

 Mazatlan, and at first recorded by us under the name of Citharicthys 

 panamensis. The specimens have, however, all been destroyed by fire. 



The name Azevia is a Portuguese name for the sole, used at Lisbon, 

 according to Brito-Oapello. It probably corresponds to the Cuban name 

 Acedia.
