SPAROID FISHES OF AMERICA AND EUROPE. A451 
Museum and described in the paper of Jordan & Swain; the other, sent 
by Poey to the Museum at Cambridge, is very similar, with well-forked 
caudal and numerous gill-rakers. The lower jaw is, however, scarcely 
projecting, and the pectoral short, 12 in head. 
20. LUTJANUS MAHOGONI. (Ojanco.) 
Mesoprion mahogoni Cuv. & Val., 11, 447, 1828 (Martinique); Giinther, 1, 203 (copied) ; 
Jordan, Proc. U. 8. N. M. 1886 (examination of type). 
Lutjanus mahogoni, Jordan & Swain, l.c. 
Mesoprion ricardi Cuv. & Val., 11, 447, 1828 (Martinique); Jordan, 1. c. (exam. of type). 
Mesoprion ojanco Poey, Memorias, 11, 150, tab. 13, f. 10, 1860 (Cuba); Poey, Synopsis, 
295, 1868. 
Lutjanus 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 M. 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, l.c.,459; Jordan & Bollman, 1. c., 1889, 181 (Panama). 
Habitat: Mazatlan to Panama. 
Etymology: Jnermis, unarmed. 
Only two specimens known; one is in the 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 other American species. It is per- 
haps related to Lutjanus mitchilli, a species lately described by Dr. 
Giinther, from Madras. 
22. LUTJANUS ARATUS. (Pargo Raizero.) 
Mesoprion aratus Giinther, Proc. Zo6l. Soc. Lon. 1864, 145 (Panama, Chiapas); Vaillant 
& Bocourt, Miss. Sci. au Mexique, 1881, 122 (Chorera, near Panama). 
Zutjanus aratus, Jordan & Gilbert, Proc. U. 8. N.M. 1881, 355; Jordan & Gilbert, op. 
cit., 1882, 625 (Panama); Jordan & Gilbert, Bull. U.S. F. C. 1882, 107, 110, 
112 (Mazatlan, Panama, Punta Arenas); Jordan & Swain, l. 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 squamation 
resembling that of Hamulon maculicauda. Specimens from Panama 
are in the museum at Cambridge.
