Museum and described iu the paper of Jordan «& Swain; the other, sent 

 by Poey to the Museum at Cambridge, is very simihir, with well-forked 

 caudal and numerous gill-rakers, Tlie lower jaw is, however, scarcely 

 projecting, and the pectoral short, If in head. 



20. LUTJANUS MAHOGONI. (Ojanco.) 



Mesoprion mahogoni Cuv. & Val., ii, 447, 1828 (Martinique) ; Giintlier, i, 208 (copied) ;

 Luijanus maliogoni, Jordan & Swain, 1. c. 



Mesoprion ricardlCnv. it Val., ii, 447, 1828 (Martinique) ; Jordan, 1. c. (exam, of type). 

 Meaoprio)! ojanco Foej, Momorias, ii, 150, tab. 1.3, f. 10, 1860 (Cuba); Poey, Synopsis, 



295, 1868. 

 Lntjanus ojanco Poey, Enumeratio, 1875, 28 (Cuba). 



Habitat: West Indies. 



Etymology: Mahogoni, the English mahogany, from the brown color- 

 ation. 



This species is rather common in the markets of Havana, where it is 

 known as ojanco, in allusion to the large eye. It does not reach a large 

 size. This is, of course, the species described by Poey under the name 

 of Lutjanus ojanco. The types of 31. mahogoni and M. ricardi, examined 

 by us in Paris, are the same as Poey's species. 



21. LUTJANUS INERMIS. 



Mesoprion inermis Peters, Berliner Monatsber., 1869, 705 (Mazatlan). 

 Lutjanus inermis Jordan, Proc. Ac. Nat. Sci. Phila. 1883, 285 (Mazatlan) ; Jordan & 

 Swain, 1. c, 459; Jordan & Bollman, 1. c, 1889, 181 (Panama). 



Habitat: Mazatlan to Panama. 



Etymology: Inermis, unarmed. 



Only two specimens known; one is iu tlie Museum at Berlin and is 

 said to have come from Mazatlan ; the other was taken by the Albatross 

 at Panama, It is quite unlike any otlier American species. It is per- 

 haps related to Lutjanus mitchilU, a species lately described by Dr. 

 GUnther, from Madras. 



22. LUTJANUS ARATUS. (Pargo Raizero.) 



Mesoprion araiws Giinther, Proc. Zool. Soc. Lon. 1864, 115 (Panama, Chiapas) ; Vaillant 

 &, Bocourt, Miss. Sci. au Mexique, 1881, 122 (Chonrra, near Panama). 



Lutjanus aratus, Jordan & Gilbert, Proc. U. 8. N. M. 1881, 355; Jordan & Gilbert, op. 

 cit., 1882, 025 (Panama) ; Jordan & Gilbert, Bull. U. S. F. C. 1882, 107, 110, 

 112 (Mazatlan, Panama, Punta Arenas); Jordan & Swain, 1. c, 460. 



Habitat: Pacific coast of tropical America. 



Etymology: Aratus, plowed, from its striped coloration. 



This species, the ^^pargo raizero''^ of the Mazatlan fishermen, is gen- 

 erally common on the Pacific coast and reaches a considerable size. It 

 bears little resemblance to any other American species, its scjuamation 

 resembling that of Ilamiulon maculicauda. Specimens from Panama 

 are in the museum at Cambridge.
