 line; pectoral ly in head ; caudal If in head ; back somewhat elevated, 

 the form of the body much as in Scicvva scicra and related species;

 tirely below level of eye ; maxillary 2§ iu head ; teeth of outer series

40. BAIRDIELLA ARCHIDIUM. 



Odontoscion archidium Jordan & Gilbert, Bull. U. S. Fish Com., 1881, 317 (Panama). 

 Jordan & Gilbert, Bull. U. S. Fish Com., 1882, lit (Panama). 



Habitat. — Pacific coast of tropical America, Panama. 



This species is not very common about Panama, where three speci- 

 mens were taken by Dr. Gilbert. Although it bears a very strong re- 

 semblance to Odontoscion dentex, it should, we think, rather be placed 

 iu Bairdiella thau in Odontoscion. It has the very small anal of Odon- 

 toscion and the spur-like preopercular spine of Bairdiella, while in its 

 dentition it is intermediate.
