exteusion of the frontal crest, and one on each side a little less than 

 half way between it and the outer edge of the supraorbital; foramen 

 above the middle of the eye on either side of this lateral crest extend- 

 ing backward into the honey-combed structure. A very high thin crest 

 extends forward from the insertion of scapula to the point of union be- 

 tween the frontal and horizontal crest; in the others this crest is joined 

 to the lateral (or horizontal) crest. Maxillary with a very large foramen 

 in front, the outer coating of the bone being very fragile, the bone much 

 smaller than in Archosargus and somewhat different in shape. Teeth 

 very long and evenly narrowed towards their base.

The specimen examined is from New Smyrna, Florida, where it was 

 obtained by Mr. P. Shannon. This is the only one yet recorded from 

 the United States. 



The account of Sargus argenteus Cuv. & Val. agrees well with our 

 specimen from New Smyrna, which is certainly the Sargus caudimacula 

 of Poey. We have therefore substituted the name S. argenteus for the 

 current name caudimacula. The types of 8. argenteus in the Museum 

 at Paris are also identified by Dr. Jordan as belonging to the same 

 species as the types of Sargus caudimacula which are in the National 

 Museum.
