534 TYPES OF FISHES IN PARIS MUSEUM. 



29. Mesoprion cyanopterus. (Cnv. and V;il., ii, 472, 1828.) 



One specirueu iu fair condition, .-7'" ionj-'; Brazil: Delalande. 



This agrees with Lu*janus cubera Poey, in all respects except that 

 the axil of the pectoral is black ou one side of the specimen and faintly 

 brownish on tlie other. This color mark may perhaps be fallacious, or 

 disappearing with age, as we have seen no cnbera so small as the type 

 of cyanopterus, 1 was unable to find the dried skin which was the type 

 oi Mesoprion paryus^ but it is probably identical with the present si)e- 

 cies. As the name cyanopterus is prior to pfirgns^ canina, cubera, or clenta- 

 ttis, this species may stand as Lutjakus cyanopterus. 



30. Mesoprion litura. (Cnv. & V;xl.,ii,467. ) 

 Cayenne: Poiteau. 



As already supposed by Jordan & Swain, this is Lutjanus JOCU.s 



31. Mesoprion flavescens. (Cuv. & Val.,ii,472.) 

 Martinique: Plee. 



This is Lutjanus caxis. 



82. Mesoprion linea. (Cuv. & Val.,ii,468.) 

 Havana: Poey. 

 This is also Lutjanus caxis. 



33. Mesoprion niahogoni. (Cuv. &. VaL, ii,447.) 



Young specimens in rather poor condition. Martinique: Plee. Also 

 similar specimens from Cuba : Desmarest. 



These are, as supposed by Jordan & Swain, identical with Lutjanus 

 ojanco Poey, which species should stand as Lutjanus mahogoni. 



34. Mesoprion ricardi. (Cuv. & Val.,ii,448.) 



This specimen is also the young of Lutjanus mahogoni. 



35. Mesoprion cynodon. (Cuv. & VaL, 11, 465.) 

 3Iartinique : P16e. 



This is a large example of Lutjanus caxis. 



36. Lutjanus dentatus Dnai^ril. ("A Dnmt^ril, Archlv. du Mus., T. 10, 245.") 

 Brazil : Delalande. S])ecimen .35"^ long. 



This is the young of Lutjanus cubera. Axil dusky. It should stand 

 as Lutjanus cyanopterus. 



37. Mesoprion vivanus. (Cuv. & VaL, 11, 454.) 



Three specimens: the largest, .19"' long; the others, .10™. 



The largest of these specimens has the dark lateral spot obscure ; 

 the depth 2| in length, equal to length of head. Maxillary 2J in head. 

 Dorsal rays X, 13 (not X, 14, as usual in L. aya). Anal fin lower than 

 usual in L. aya, its longest rays about half head. Iu spite of certain 

 small differences, I still hold my opinion that these specimens are the 

 young of our common lied Snapper, which 1 call Lutjanus aya.
