150 DR. RICHARDSON'S DESCRIPTION OF AUSTRALIAN FISH. 



the mouth to the cheek. There are no configurations of colour on the body. A spe- 

 cimen since received from Port Arthur, preserved in brine, exhibits a dark purple 

 edging on the dorsal and anal fins, which are also marked by many very short, slender 

 oblique bars, regularly crossing the rays. The end of the caudal is dark. The colours 

 of the body are faded.

An example of another species having a dark stripe which is wanting in algensis, was 

 sent by Mr. Lempriere, but it is too much injured to admit of identification. It is pro- 

 bably the Odax balteatus of the ' Histoire des Poissons,' a fish discovered by Peron. 



A New Zealand Odax is described in Solander's MSS. ' Pisces Australia;,' which 

 differs from the Odax pullus of Forster and the ' Histoire des Poissons ' in colour. " Cal- 

 liodon vittatus. — Totus piscis castaneo-umbratus suhtus multo pallidior. Vitta ex incarnato- 

 argentea, utrinque sub basi mandibulce inferioris incipiens, sub oculis ducta, per basin pin- 

 narum pectoraliurn, media latera ad basin pinna analis extensa. Sape macula; in seriebus 

 longitudinalibus per dorsum et latera dispositw. Piscis adultus sesquipedalis a junioribus 

 valde variat et proportions et colore. Adulti crassi sunt, cum capite parvo, guld gibbosius- 

 culd, abdomine late rotundato. Vitta lateralis e maculis magnis sordide carneis interrupta, 

 non continuata. Pinnee dorsi et anipostice altiores. Br. 6; D.34; P. 14; V. 5; C. 14." 

 (Sol. 1. c.) The total number of dorsal rays in balteatus does not exceed twenty-eight, 

 while in pullus they are 23|11, being the same in amount as in vittatus. The native 

 place of balteatus is not mentioned in the ' Histoire des Poissons ' ; pullus was taken by
