Head 3f in length of body ; depth 5^ ; D. I-IO ; A. 1-14 ; scales

 vent respectively). 



Body little compressed; snout short, obtuse,3Mnpremaxillary ; 

 mouth large, premaxillary If in head ; interorbital area concave, 

 about 6^ in head, upper surface of head rugose. Dorsal slightly 

 higher than long, its length H in head ; origin of dorsal fin mid- 

 Way between tip of snout and adipose fin, slightly behind last 

 fays of ventrals. Anal fin long, its base nearly equal to head ; 

 pectorals reaching root of ventrals, 2 in head ; tips of ventrals 

 almost reaching vent, ventrals 4^ in length of body ; caudal 

 forked ; teeth comparatively small ; lower jaw slightly projecting. 

 Color grayish, mottled with darker above ; body with eleven 

 cross-bars ; a black blotch on scapula ; a black streak extending 

 from eyes around s^^mphysis, forming a quadrated blotch on the 

 side of each jaw, and one on the median line of each jaw ; dorsal 

 fin faintly barred ; pectorals, ventrals and anal plain. 



This description is taken from a very young specimen, twenty 

 three inches in length, collected by Professor Jordan in Havana. 

 In the above synonymy we have omitted references from the 

 Pacific Ocean, thinking it not impossible that the Asiatic species 

 (limbatus) is a species distinct from S. myops. Trachinocephalus 

 hrevirostris Poey, known only from a drawing made in 185T, 

 seems to differ only in the presence of ten .instead of fifteen anal 

 rays. This is probably an error, or perhaps an accidental muti- 

 lation. I have little doubt that it is a synonym of S. myops.
