Snout short and obtuse, not projecting beyond mouth. Length 

 nearly six times that of the head, which latter is longer than the 

 greatest depth of body, and measures three times the length of 

 snout. Diameter of eye scarcely equal to length of snout. Barbel 

 rudimentaiy. Scales small, smooth, without ridges or spines. 

 There are eight series .of scales between anterior dorsal and the 

 lateral line. The lateral line is composed of about 133 series of 

 scales, the pierced scales being interrupted. The first dorsal is 

 composed of 15 feeble jointed rays, the length about twice the 

 diameter of the eye. The second dorsal commences near to the 

 termination of the first dorsal. The anus is situated under the 

 17th ray of the second dorsal, and neai'er to the snout than to the 

 tail by twice the length of the snout. Uniform silvery plumbous. 

 with a purplish shade. (Johnston.) 



Seen in shoals at some seasons between Port Davey and 

 Macquarie Harbour, known as the " Tasmanian Whiptail."

Species 780. Pseudorhombus Russellii. 



Klunzinger makes the P. polyspilus Bleek, regarded by 

 Gunther as a synonym of Russellii, as a different species. He 

 is probably right, the markings and the dentition are certainly 

 a little different. He gives King George's Sound as its locality.
