In the double nasal cilia, and connexion of the caudal with the 

 dorsal and anal fins, this little fish agrees with L. cornubicus (Flem.), 

 Yarr. 2. 264. The structure of the sucking disk is also similar to 

 the representation of the same part in that species, and not to that 

 of the " bimaculated Sucker," at p. 268. In this particular it per- 

 fectly agrees also with the former species indicated in my Synopsis, 

 p. 190; which is, however, perfectly distinct specifically, having 

 neither a nasal cilium nor the caudal fin united with the dorsal and 

 anal fins. Of this last-mentioned species no second example has 

 yet occurred. The present (L. zebrinus) is not by any means un- 

 common. It varies considerably in intensitj"^ of colour, and in the 

 distinctness of the darker stripes upon the nape and flanks. The 

 nasal ciliae are of the general dark brown or blackish tint.

The nearest ally of this very distinct species appears to be E. lu- 

 nata. Bancr. in Zool. Journ. V. 413. t. 18. But this, besides other 

 differences, has a lunate tail.
