cleft of mouth extending to below the anterior border of 



28 to 36* '> 



the eye. Dentition— I. -^^^-^—-^; C. t; lower canines 



much the longer. Lateral line incomplete, consisting of 

 about 6 tubes, and ceasing nearly above the tip of the 

 appressed pectoral. 



Dorsal fin originating above the base of the pectoral, 

 the rays increasing in length to the 3rd, beyond Avhich 

 they are subequal, ; longest articulated rays behind the 

 middle of the soft fin and 1-5 time the height of the last 

 spinous ray ; membrane of last dorsal ray extending slightly 

 beyond the base of the cftudal. Anal fin originating below 

 the 2nd dorsal ray. Caudal fin rounded. Pectoral 

 rounded, the 8th ray longest, not nearly reaching to the 

 vertical from the vent. Ventral short, the inner ray 

 slightly the longer. 



Gill-opening in front of and above the base ot the 

 pectoral, its width 5-5 in the head. Vertebrae 11+29=40. 



Olive-green, darkest anteriorly, the lower surface 

 tinged with yellow ; trunk with 3 to 5 horizontal bars, 

 which disappear above the vent ; the upper, however, 

 is continued as a series of distant spots to below the middle 

 of the soft dorsal, and along the middle of the tail there 

 is a series of spots or vertical bars extending to the caudal 

 fin. Head with 3 faint vertical bands, which meet across 

 the under surface, where they show distinctly on the lighter 

 ground. Fins violaceous, the tips of the anal rays white. 



This blenny has been recorded from the coasts of 

 Eastern Australia and Southern Japan, and attains a length 

 of 110 millim. The remarks under the preceding species 

 apply with equal force to this, which is not, however, so 

 numerous. I obtained one specimen only in Great Sandy 

 Strait, and one, an exceptionally fine example, at Woody 

 Point, Moreton Bay. 



Described from 6 specimens measuring from 62 to 110 

 millim., among these being Mr. De Vis.' types. Cat. Nos. 

 in A.F.A.Q., 907 and 1123.

* The incisors increase in number with the age of the fish ; Jordan 

 and Snyder give " 26 to 28 " as the formula of P. daston, Bleeker "36 to 

 40 " as that of P. japonicut.
