south, and it is apparently not so abundant 

 anywhere on the mainhind as the other species. 



Virtually nothing has been published about its 

 life history, and the few individuals taken during 

 the seining program of the Biological Laboratory 

 at Brunswick on the Georgia beaches do little 

 to augment present knowledge. Twelve individ- 

 uals, 19.4-61.0 mm., have been taken. All were 

 collected from August to November. 



Size and Food 



As with the other species, the maximum size 

 of T. glaucus is uncertain. Beebe and Tee-Van 

 (1933: p. 108) said that it grows to about a foot. 

 Carvalho (1941: p. 55) stated that its food con- 

 sists of crustaceans and small fish. Examination 

 of stomachs of the Laboratory specimens pro- 

 duced amphipods, bivalve mollusks, diptera, 

 stomatopods, hymenoptera, crabs, fish, and iso- 

 pods, in that order of significance.
