FAMILY, XXX— BLENNIID^. 329 



Some of these fishes have been constituted into a distinct Genus, AJticus, Cotn.^^Eiipiscartes, Swains, the 

 differences between which and Salarias is thus characterized by Bleeker: — Lateral-line absent. Body 

 elongated, anteriorly loider than high. No tentacles at nostrils or najpe. Ventral with four rays : caudal rays simple. 

 But Salarias Andersonii. is unquestionably an Alticus, with the lateral-line present. Andamia is an AUicus, 

 possessing a sucker, whilst its nostril is a little tubular and prolonged. Altic^is, as at present known, would 

 consist of S. Kirkii, S. tridactylus, S. monochrous, S. aspilus, S. Andersonii, and S. heteropterus.
