Chissijication of the Blennioid Fishes.

in contact, narrow, especially the latter, wliieii is not deve- 

 loped below the base ot the pectoral fin ; radials elongate, 

 4 in number (tig. 1, A) ; pelvic bones short, firmly attached 

 at the cleithral symphysis. 



Principal genera : Ophioblennm.f, Blenmus^ Salarias, 

 Andamia, Chasmodes, Petroscirtes, Xiphasia, from tropical 

 and temperate seas. 



In Ophiobltnnius wehhii I find that the comb-like outer 

 series ot teeth is developed, although very small ; this genus 

 differs from other Blenniidge in tlie presence of symphysial 

 canines and of more than one lateral canine in the lower jaw. 

 Xiphasia has the head, mouth, teeth, gill-openings, &c. of 

 Pelroscirtes, but differs from that genus in the very long tail 

 and greatly increased number of fin-rays and vertebra.
