Total length, 13J inches. 



This fish was figured by mistake in the " Catalogue of the Fishes of New 

 Zealand," PI. YIL, No. 68, instead of L. hothryocosmus. 



70. Odax viffatuSj Sol. (Cat., p. 43.) 



The following description is taken from a stufifed and highly- varnished 

 specimen in the Otago Museum : — 



D. 34; A. 15; Y. | ; P. 15; C. 14; L. lat., 75? L. trans., 8/16? 



Length four and a half times that of the head, which is equal to the height 

 of the body ; length of the head nearly three times that of the snout ; least 

 depth of the tail less than half the distance between the dorsal and caudal ; 

 prseoperculum sharply serrated ; operculum with two points. 



71. Coridodax pullus, Forst. (Cat., p. 44.) 



Length four and two-thirds that of the head, or three and three-fifths that 

 of the body ; length of the head three and a half times that of the snout. 



Purplish grey, lighter below, often with a broad pale band on each side 

 from the mouth to the caudal ; mouth, prseoperculum, anal, and dorsal fins 

 variegated with bright french blue ; belly and under the pectorals sparingly 

 variegated with yellow ; lips purplish red ; ventrals and pectorals variegated 

 with the same colour. 



72. Gadus australis, Hutton. (Cat., p. 45.) 



In a letter to Dr. Hector, Dr. Giinther says that this fish should be 

 referred to the genus Merluccias, and that it is probably identical with 

 M. gayi, from Chile, an opinion with which I quite agree. 



74. Lotella rhacinus, Forst. (Cat., p. 46.) 



Mr. H. Travers brought specimens of this fish from the Chatham Islands. 

 They are of a pale uniform brown in spirits. 



Calloptilum, gen. nov. 



Body fusiform, compressed posteriorly ; scales cycloid ; three dorsal fins, 

 the first reduced to a single ray ; anal single, long ; ventrals long, composed 

 of two rays ; caudal separate ; teeth none ; gill openings wide, the gill mem- 

 brane united below the throat, but not attached to the isthmus ; pseudo- 

 branchisa none ; snout short and rounded. 



This genus comes next to Bregmaceros, Thompson, afterwards called 

 Calloptilum by Sir J. Richardson, which name I have now adopted for the 

 present genus.
