60 ON NEW OR INSUFFICIENTLY DESCRIBED FISHES 



indistinct and ceasing altogether before the middle of the 

 tail, the posterior half of which is adorned mth numerous 

 small blue spots ; the dark band behind the eye is usually 

 broken up in two oval or lunate spots ; all the fins are 

 uniform gray except the spinous dorsal, which has a basal 

 series of dusky spots. 



This pretty little blenny is an inhabitant of the East 

 Coast of Australia from Port Jackson to the Wide Bay 

 District, beyond which points it has not yet been traced 

 though it doubtless occurs. It is exceedingly abundant 

 on all the rocky sections of the foreshores and islands of 

 Moreton Bay, where it is one of the most common objects 

 of the rock-pool fauna. In the Great Sandy Strait I found 

 it scarce, the environment probably being unsuitable to its 

 habits. 



Described from 10 specimens, 45 to 85 millim. long, 

 in the A.F.A.Q. Museum ; Cat. Nos. 71 and 1145.

* The author cannot, without demur, admit the accuracy of some of 

 Mr. De Vis' earlier descriptions, and finds himself compelled to class most 

 of the species of Salarias described by Mr. De Vis, as belonging to the 

 genus Petroskirtes.
