Two specimens 4| and drs inches long from Panama Bay. M. C. Z. 29451 

 (1 specimen). 



The larger specimen had the head 3.69 in length without caudal; depth 

 4.11; eye 4.14 in head; snout 2.90; maxillary 1.81; mandible 1.61; pectoral 

 2.23; soft dorsal 2.41; anal 2.41; dorsal XVII-I, 16-1-1-1-1-1-1-1-1; anal 

 II-16-l-l-l-l-l-l-l-l. The other specimen had the head 3.91 in length 

 without caudal; depth 4.94; eye 4.57 in head; snout 3.27; maxillary 1.77; 

 mandible 1.65; pectoral 2.40; soft dorsal 2.18; anal 2.18; dorsal XVIII-I,

Soft dorsal, in larger specimen, is separated by a slight space; in smaller 

 specimen there seems to be no separation. The insertion of the dorsal in both 

 is somewhat in advance of the origin of the anal.

 on sides ; a small dusky area on lower posterior margin of orbit ; spinous dorsal

 are too small for certain identification.
