ANALYSIS OF GENERA 



o\ Areas before and below eyes ruoderate, so preorbital extent 

 equals eye. 

 &\ Scutes of lateral line each with 2 well developed spines which 



subequal or upper little larger Oplichthys 



b". Scutes of lateral line each with large single strong spine, di- 

 rected up and back, so only single row of spines formed along 

 each side of back ; sometimes auxiliary small spine in inter- 

 spaces between scutes and in line with lax'ger spines Monhoplichthys 



6'. Scales of lateral line each with large, erect, strong spine, be- 

 sides an inner smaller superior spine, these forming 2 series 

 of lateral spines, of which upper smaller and less 



conspicuous Pristhopliclithys 



a'. Areas before and below eyes large, smooth and elongate, 1 to 



1^4 times eye diameter Rhinhoplichthys 



MONHOPLICHTHYS, new genus 



Type. — Monhoplichthys gregoryi^ new species. 



Scutes of lateral line each with large single strong spine, directed 

 up and back, so only single row of spines formed along each side 

 of back. Sometimes auxiliary small spine in interspaces between 

 scutes and in line with larger spines.
