above the angle and on lower limb below the angle ; the serrre above the 

 angle are very fine; at the angle stronger, the lower limb entire. 



Nostrils not very near together. Distance between them 8 in longer 

 diameter of eye. The anterior with a flap, circular. Posterior elliptical 

 and not more than twice the diameter of the anterior. 



Gill-rakers of anterior arch rather short, the longest about 2 in eye. 

 Breadth of base about 2.5 in length. About 9 developed and 2 rudi- 

 mentary ones on lower branch, one in the angle, 2 well developed ou 

 upper branch, with a few others rudimentary ; on succeeding arches, 

 all very short, being but knobs, or hardly developed. 



Teeth on lower jaw in about two series, strong. On upper jaw sev- 

 eral strong ones intermingled with many small ones. Two prominent 

 canines in each jaw. 



Caudal fin very slightly lunate. The outer rays scarcely longer than 

 inner, 2 in head ; pectorals reaching beyond the tip of ventrals, being 

 5 in the body and 1.9 in the head ; ventral fin shorter than the pectoral, 

 G.25 in the body, its spine 4 in head. 



The first three spines of the dorsal are graduated. The first 8.8, the 

 second 4.2G, the third 3.3, in head. The tenth spine is 4, and the eleventh 

 is 3.8, in head. The longest soft ray, the sixth, is 2.3 in head. The 

 origin of the dorsal is a little less than the leugtu of the head from the 

 tip of the snout. 



The anal spines are graduated, the first 14.4, the second 6.4, the third 

 5.2 in the head. The fin is evenly rounded, the longest soft ray is 2.3 f 

 and the last 4.8 in the head. 



Color in alcohol, much as in E. bonaci Poey, brown with irregular 

 darker mottlings of considerable size, but varying much; belly paler; 

 dorsal and anal fins of the general color of the body, the anal having 

 the lower edge pale, the outer margin not evidently darker; ventrals 

 black with the tip white; pectorals paler. 



This species is nearly allied to E. microlepis Goode & Beau, from 

 which it differs in the shorter maxillary, in the form of the caudal, which 

 in this species is less lunate, iu the smaller eye, in the wider interorbital 

 space, and iu the smaller number of gill-rakers. 



It is also allied to E. bonaci Poey, from which it differs in the shorter 

 maxillary, iu the less robust body, smaller eye, wider interorbital space, 

 and iu the smaller number of gill-rakers. 



We follow Dr. Jordan's manuscript in using the name Epinepliehts, 

 instead of Mycteropcrca or Tristropis. The original type of Epincphelus 

 was E. ruber Bloch, which is probably identical with Mycteroperca, 

 acutirostris. 



This species is dedicated to Dr. David S. Jordan. This fish is rather 

 common in the bay at Guaymas, where we obtained several specimens, 

 and at which place it is in great favor as a food-fish.
