Order InIOMI 



Synodontidae 



Determinations of the material in this family were made with the 

 aid of a manuscript key to the family made available to us by William 

 W. Anderson and Jack W. Gehringer of the United States Bureau of 

 Commercial Fisheries. Their key will appear in a section of a forthcoming 

 volume of the Sears Foundation series. Fishes of the Western North 

 Atlantic. 



Saurida sp. 



Material: A 52-39, 1 (43.1 mm.), AHF 2836, from Caledonia Bay, 

 Panama. 

 Remarks: The condition of the material precluded specific de- 

 termination, 



Trachinocephalus myops (Forster) ? 



Material: A 7-39, 1 (anterior portion only), AHF 2837, from Cale- 

 donia Bay, Panama. 

 Remarks: This poor specimen, cut off shortly behind the pelvic fin 

 insertions, had no vomer and possessed eight rays in each pelvic fin. It 

 was clearly of this genus and is almost certainly T. myops. 



Order APODES 



Moringuidae 



Aphthalmichthys caribbeus Gill and Smith 



Material: A 57-39, 1 (295 mm. T. L.), AHF 3041, from Caledonia 

 Bay, Panama. 

 Remarks: We did not see this specimen. Dr. James E. Bohlke, 

 who is studying it at this writing, wrote that it is currently recognized 

 as this genus and species, but that a future change in both names is 

 likely.
