[47] FLOUNDERS AND SOLES. 271 
Habitat.—West Indian fauna. Key West to Rio Janeiro. 
We have found in the Museum of Comparative Zoology specimens 
purporting to be the types of Hemirhombus ocellatus Poey (No. 11144; 
Poey’s number, 88). These are female specimens, and they differ from 
the types of Hemirhombus ethalion, 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 ethalion. 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 Hemirhombus aramaca.. 
This fish is described and fairly well figured by Ranzani 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. 8. 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 1n this species have 
not been studied. 
49. SYACIUM OVALE. 
Hemirhombus ovalis Giinther, Proc. Zool. Soc., 1864, p. 154. Giinther, Fish. Central 
America, p. 472, 1869, plate Ixxx, fig. 1. (Panama.:) Jordan & Gilbert, 
Bull. U.S. Fish Com., 1882, p. 108-111. (Mazatlan; Panama.) 
Citharichthys ovalis 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 bave 
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-Capello. It probably corresponds to the Cuban name 
Acedia.
