Then follows the description of a small Odax, known at Port 



Arthur by the name of " Kelp fish." It agrees with Odax semifas- 



ciatus of the Histoire des Poissons in many of its details, but on a 



minute comparison with the description of that species it appears to 



be distinct. 



Odax algensis. Od. capite longiusculo ; prceoperculo denticulato ; 



facie utrinque sex-striatd.

Another species of kelp- fish common at Port Arthur, and of which 

 a specimen was sent by Mr. Lempriere, but too much decayed for 

 identification, is described by that gentleman as being marked with 

 a dark stripe. It is probably the Odax balteatus of the Histoire des 

 Poissons which was discovered by Peron. 



The author then describes a new scaroid fish which did not form 

 part of Mr. Lempriere's collection, but which there is reason to be- 

 lieve was taken either at Hobart Town or Sydney. It was presented 

 to the Museum of Haslar by Mr. Conway, formerly medical super- 

 intendent of a convict ship, and since deceased. The specimen 

 being a mounted one, no details of internal structure can be given, 

 and in so far the characters of the genus or sub -genus are incom- 

 plete ; but it differs from the ordinary Labri in the scaliness of the 

 vertical fins, and from Scarus in external aspect, the form of the fins, 

 the smallness of the scales, especially at the base of the caudal fin, 

 and in the manner in which the lips cover and move with the jaws. 

 It differs from Odax in the teeth and ventral fins. 



Or-LEGNATHUS, genus novum. 

 Corpus ellipticum, crassum, squamis parvis oblongis tectum. Man- 

 dibulce modo Scarorum dentes incorporates gerentes. Labium 



* The character of this species being rendered obscure in the abstract of 

 the former paper by the omission of a word in printing, is here repeated.
