Body slender, subfusiforin, little compressed. Head moderate, not 

 very blunt, the anterior profile somewhat evenly decurved, the snout not 

 very short, scarcely- shorter than the large eye. Mouth not very large, 

 horizontal, the lower jaw included, the maxillary extending slightly be- 

 yond front of pupil ; its length about 3 in head. Teeth small, slender, in 

 narrow bauds, those of the outer series longer than the others. Eyes 

 placed high, abont 4 in head ; iuterorbital space not wider than pupil. 



Scales moderate, ctenoid ; those on nape and belly not much reduced 

 in size. 



Gill openings not continued forward above opercle. 



First dorsal with the spines slender but rather firm, none of them 

 filamentous, the longest about three-fifths head. Second dorsal and 

 anal rather large. Caudal long, pointed, slightly longer than head. 

 Pectorals large, slightly longer than head, none of the upper rays 

 silk-like. Veutrals slightly shorter than head, inserted below axil of 

 pectorals. 



Many specimens of this species, the largest about 2 inches in length 

 were obtained in the Laguna Grande at Pensacola. It lurks in sea 

 wrack on muddy bottoms in very shallow water (G to 12 inches). In 

 form, size, coloration, and movements, this little fish bears a remarkable 

 resemblance to the percoid, Boleomma olmstedi.
