Scales rather small, regularly arranged; those above lateral line in 

 series, which are throughout parallel with the lateral line ; those below 

 in horizontal series. Temporal region with a band of one or two series 

 of large scales. Cheeks with about seven rows of scales. 



Dorsal si)ines rather low and strong, the fin somewhat deeply emar- 

 ginate. Soft dorsal high, angular, or pointed in outline, the last ray not 

 two-fifths the height of the middle ones, which are two in head. Caudal 

 short, feebly lunate, the upper lobe ] f in head. Anal high and pointed, 

 as in Luijanus analis, vivatws, and Colorado, the middle rays reaching 

 base of caudal, a little more than half length of head. Anal spines 

 strong, the second longer and stronger than third, 2| in head. Pectoral 

 long, 3 in head ; ventral 1^. 



Color in spirits, olive brown, the body with about six rather con- 

 spicuous narrow whitish cross-bands, extending a little obliquely back- 

 wards, and broadest below. These are irregular in number and in 

 width. A round, duskj' blotch rather faint on base of last rays of soft 

 dorsal. Fins mostly dusky olive, the pectorals pale, the ventrals and 

 anal darkest. Top of head with some small dark spots. 



This most remarkable species is a common food-fish of Mazatl^u, 

 where it is known as Pargo. 



Dr. Gill has very properly considered it the type of a distinct sub- 

 family, E.oplopagrina\ Its peculiarities are certainly stronger than 

 those of the other genera associated with Lufjanns.

analysis of SPECIES OF LUTJANUS.* 



a. Dorsal spiues, normally 10. 

 b. Anal rays III, 7 to III, 9. 

 c. Gill-rakers comparatively few, 7 to 15 developed on lower i)art of anterior arcb, 



sometimes preceded by 1 to 5 rudiments. 

 d. Anal fin rounded or but sligbtly angulated, its middle rays less than balf 



length of bead. 

 e. Lower jaw not projecting beyond upper. 

 /. Soft dorsal normally with 14 rays. 



g. Developed gill-rakers, 7 to 9, with but one or two rudiments, if any ; 



canines strong, no black lateral spot, preorbital, 

 deep, caudal lunate. 



* In this analysis we omit L. cyanopterus and L, lutjanoldes, species which we have 

 never seen, and of which little is known.
