aciituni, differing in the color, in the larger size of the scales, and the dif- 

 ferences in their arrangement, and in the longer snout and smaller 

 mouth. 



The synonymy of this species and the next is badly entangled, and 

 we are not sure that we have correctly distributed it all. Our fish seems 

 to correspond to Hwmulon canna of Giinther, and apparently to the 

 Hcemulon notatum^ continuum and retrocurrens of Poey. The other 

 names of Poey {acutuniy alhidum and serratum) seem to refer rather 

 to the next species. This species seems to be the one to which the name 

 Diabasis parrce and its synonym Hcemulon caudimacula were originally 

 given. It agrees much better than any of the other species with the 

 account of the type of parrce and caudimacula sent to us by Dr. H. E. 

 Sauvage, and published by us in the Bull. U. S. Fish Comm. 1881, 322. 

 If this identification is correct, the specific name jparrfp is the one to be 

 adopted, having clear priority over all others. 



NOTE ON THE Di^CADE ICHTHYOLOGIQUE OF DESMAREST.* 



We are indebted to Professor Poey for a copy of this rather rare work. 

 It is in some regards an imitation of the excellent Ichthyologia of 

 Broussonet (1782), and like that work was intended as one of a series 

 of publications which should give detailed descriptions and accurate 

 figures instead of the miserably brief diagnoses which prevailed in 

 zoological works at that time. The work of Desmarest compares very 

 favorably with most others published before Cuvier. The descriptions 

 are fair, and the figures, except for a certain uniform snuffy brownness 

 of the coloration, are well executed and characteristic. All the species 

 mentioned by him were collected in Havana by Marcellin Fournier. 



The following are the species mentioned with our identification of 



them : 



TrygonohatHS torpedivus, p. 6 (pi. 7)t = Urolo/ihiis torpedinus. 

 Priacanihus Cepedianns, p. 9 (pi. 1)^ Priaeanthus cepedianus.t 

 Luljanus aciitirostris, p. 13 (pi. 3, f. 1) = Lufjanus caxis, (Bl. & Schn,). 

 Luijanus Aubrieti, p. 17 (pi. 4, f. 1) = Lufjanus synagris, (L.). 

 Vmhrina Fiolurnieri, p. 22 (pi. 3, f. 2) = Micropogon fournieri . 

 Acanthurus Broussonetii, p. 26 (pi. 4, f. 2) ■= Acanthurus coeruleus, Bloch. 

 Diabasis Parra, p. 30 (pi. 2, f. 2) = Hcemulon parrw. 

 Genus Diabasis, p. 34 := Hwmulon Cuv. 



Diabasis flavoUneatus, p. 35 (pi. 22, f. 1) = Ha;mulon flavolineatum. 

 Eques punctatus Schueider, p. 40 (pi. 4) =^ Eques punctatus, Schn. 

 Holocanthus coronatus, p. 44 (pi. 6) = Holacanthus ciliaris, (L.).

 does not correspond with that intended by the author, who quotes, in the text for T. 

 torpedinus, " pi. 1, f. 1," and, for P. cepedianus, "pi. 1, f. 2." 



t A species distinct from P. catalufa, according to Poey.
