470 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



exiunples. This is true uotably of sciurus, carhonarium, andjicirra. The 

 l)ale form of sciurus has even received a different specific name [multi- 

 Uneatum)^ but we have no doubt that these differences depend on the 

 character of the water or the bottom, and not on difference of species. 

 This is evidently tlie Ihvmidon album of Cuvier and Vak'nciennes. 

 0\mthev''s IT. mierojMlialtti urn belonj;s to the same species. Tlie mar- 

 gate-fish of Catesby, erroneously referred by Linna*us to his Perca 

 chryHoptera {PristipoinafidvomaculaUou), and by Cuvier tohis JTrtw?^/o« 

 chrysopternm (rimator), evidently belon<;s here. The diUlodim gibhosns 

 of Blodi and Schneider is based on the figure of Catesby, which, to- 

 gether with the Perca chrysoptcra L., is quoted in the synonymy. Still 

 older is the name Perca gibhosus of Walbaum, likewise based on 

 Catesby's margate-tish. But the name Perca (jihbosa is iDreoccupied, 

 having been used by Linnaeus for the common sunfish, Lepomis gibbosus. 

 The name H(emulon album sliould therefore be retained.

Besides the specimens examined by Jordan & Swain (Clearwater 

 Harboi», Key West, Jamaica) we have examined specimens in the 

 museum at Cambridge from Florida and St. Thomas. The large speci- 

 men from St. Thomas, a foot in length, is ])erfectly unicolor, only some 

 of the upper scales having darker centers. After carefnl consideration 

 we have decided that H. macrostoma Giinther and H.fremebundum 

 Goode «& Bean must be identical, although ther«^ are one or two slight 

 discrepancies in (iiintlier's description.
