In consequence of the bad state of preservation of the single spe- 

 cimen in the Paris Museum, Valenciennes has not recognized the 

 close affinity of this species with those from the East Indies ; and the 

 description given by the French naturalist, and still more the figure, 

 are incorrect in several respects. The dentition does not differ from 

 that of the Indian species, the teeth of the outer series being rather 

 smaller and more numerous. The eye, so distinctly represented by 

 Valenciennes, is small and indistinct. The situation of the six dorsal 

 spines is exactly the same as in the East Indian species, the sixth 

 being placed at some distance from the fifth and from the first ray 

 belonging to the soft portion. The vertical fins are contiguous, and 

 the dorsal and anal are separated from the caudal only by a slight 

 notch, 



I have preserved the name of Amhlyopus for the whole genus 

 because it is generally used, and also because such names as Gohioides, 

 Tfenioides, &c., should always be avoided.
