Mesoprion candanotatus^ but its identity with L. huccanella is imques- 

 tionable. 



10. Lutjanus brachypteriis. 



LutjavHs hradujpierus, Cope, Trans. Am. Phil. Soc, 1871, 470 (New Provi- 

 dence). 



Ilahitaf. — Baliama Islands. 



nead, 23; dei)tb, 3. D. X, 12; A. Ill, 8. Scales (C), 8-51-x ; 47 

 l)ores. 



Form of Luijcmus griftens. Maxillary, 2i iu Lead, reaching to past 

 front of eye. Canines very small, developed in upper jaw only. Tongue 

 with an oval patch of teeth. Vomer with a A -shaped patch of teeth; 

 there being a short backward projection on the niediiin line. Eye rather 

 small, 4f in head. Gill-rakers few, arranged as in L. griseus. 



Scales above lateral Hue arranged in very oblique series. Two bands 

 of small scales on temporal region. 



Anal fin low, its longest rays 2f iu head. Second anal spine about 

 as long as third, 3-| in head. Caudal little forked, its longest rays li 

 iu head. Pectoral fin short, 1| in head. Color in spirits, olivaceous, 

 with silvery luster below ; rows of obscure dusky s^iots aloug the scales 

 on sides and yellowish oblique streaks above the lateral line. Fins 

 rather dark, the caudal not pale; no black lateral spot. 



The above account is taken from Professor Cope's original type iu the 

 Museum of the Academy at Philadelphia. The species is allied to 

 L. griseus, although apparently distinct from that species and from all 

 others known to us. In its technical characters it approaches most 

 closely to L. synagris, near which species it is convenient to place it in 

 our analytical key. If we suppose the type of X. amhiguus to be a hy- 

 brid, synagris-clirysurus^ we may suspect L. hrachyptcrus to represent 

 a hybrid of griseus and synagris. The evidence in the latter case is less 

 striking than in the former.
