POGONOCULIINAE, new subfamily 

 POGONOCULIUS, new genus 



Type. — Pogonoeulius zebra., new species. 



Body elongate, greatly compressed. Head small, short, com- 

 pressed. Snout short, obtuse. Eye moderate, well advanced and 

 high in head. Mouth terminally superior, subvertical. Mandibular 

 bones well separated, protrude before snout, interspace of chin deep, 

 with median free tentacle nearly long as combined snout and eye, 

 and followed by dermal ridge to isthmus. Teeth large, simple, 

 uniserial. Gill openings lateral. Body largely scaled, small irregu- 

 lar scales only distinct on tail posteriorly. Two dorsals, spines 6, 

 rays 28. Anal rays 26, fin like second dorsal and opposite. Caudal 

 peduncle short, free. Caudal moderate, truncate. Pectoral short, 

 rounded, with broad base. Ventrals close, distinctly separated and 

 much longer than pectorals. Vent close before anal. 



Unique in the mental tentacle and combination of structural char- 

 acters, such as the small head, long ventrals, strong dentition, long 

 second dorsal and anal, etc. It is perhaps related to Ptereleotris 

 Gill, differing sharply in the characters noted above, especially its 

 obsolete lepidosis, coloration, general appearance, and other 

 characters.
