Body rather slender, subterete, covered with moderate-sized 

 scales; head large; maxillary small, less than ^ head, scarcely 

 reaching orbit ; lower jaw bluntly conical, without fleshy tip ; 

 Eye rather large, 5| in head, a little exceeding interorbital area ; 

 interorbital area flat ; median groove very shallow, the median 

 longitudinal ridge very small, anterior ; supraocular ridge bony, 

 striate ; preocular ridge large. 



Premaxillary teeth small, 35-40 in number ; premaxillar}"^ 

 teeth present ; anterior palatine teeth larger and more compressed 

 than those on premaxillary, widely set, decreasing in length 

 gradually ; teeth in lateral series of lower jaw small and closely- 

 set anteriorly, larger and wide-set posteriorly, about 10 in number ; 

 a large compressed tooth at symphysis. 



Origin of first dorsal over above tip of pectoral, slightly behind 

 the ventrals ; distance between dorsals 5j in body ; distance from 

 tip of snout to spinous dorsal 2^11 body; scales moderate, almost 

 uniform in size ; cheeks and opercles scaly ; upper part of head 

 with small imbedded scales. 



Color light olive, yellowish on soft dorsal; anal and ventral tips 

 of caudal rays black ; top of head dark ; dark punctulations oh 

 upper part of body ; spinous dorsal with some dark punctulations. 



The description of this species is taken from three specimens 

 from Havana, Cuba, varying in length from six and one-half to 

 eight inches, and from one specimen collected by Mr. Stearns, 

 from Pensacola, Fla., nineteen inches in length. 



Below is given a table of measurements of specimens we have 

 examined. The proportions are given in hundredths of length 

 from tip of snout to the end of last vertebra.
