OpMchthys cdebicus was founded on two very young examples, 

 said to have the maxillary and vomerine teeth in three series. One 

 of these typical examples, which I have examined, has the max- 

 illary teeth distinctly enough in two series on one side, whilst on 

 the other the two series are a little more irregular. The vomerine 

 teeth are biserial. The representation of the dentition in Bleeker's 

 atlas is a schematic figure, like many others in the plates contain- 

 ing the Muroenidae, and very different from the real arrangement of 

 the teeth.
