distinct teeth. Since the specimen agrees in all other details 

 with his description, and has a label 'Agonostomzis norfol- 

 censis' tied to it, which is in his own handwriting, there can 

 be no donbt of its authenticity. 



"Other smaller specimens in the Australian Museum 

 collection are labelled ' Agonostomus, sp./ and are doubtless 

 those upon which the record of this genus from Norfolk Island 

 is founded. They are also M. elongatus." 



The accompanying plate (xliv.) representing this species

 of the "Thetis" Trawling Expedition. 



Family APOGONICHTHYIDAE.

B. vi. ; D. vii. i. 9 ; A. ii. 13 ; P. 11 : V. i. 5 ; C. 17 + 6 ; 

 L. lat. 27; L. tr. 2 + 7. 



Length of head 2"76, height of body 2" 65, and length 

 •of caudal 3"63 in the length. Diameter of eye 2'5, inter- 

 orbital space 3"84, and length of snout 5'0 in the head. 



Head and body compressed, profile of head from snout 

 to the highest point, which is just in advance of the dorsal 

 tin, almost straight, slightly tumid above the eye. The profile 

 from the highest point to the origin of the soft dorsal is 

 slightly concave; it thence falls more rapidly. The ventral pro- 

 file is more even and convex; interorbital space nearly flat. 

 The snout is rather blunt, the jaws equal; the maxilla reaches 

 to below the middle of the eye, and its distal extremity is 

 pointed above and rounded below, its width being 3*3 in the 

 diameter of the eye ; opercles finely serrated. Gills four, a 

 slit behind the fourth ; gill-rakers long and thin, twenty-five 

 in number on the first arch, of which twenty are on the lower 

 limb. Pseudobranchiae present. Vent one-third nearer to 

 the anal than to the ventral fins. 



Teeth. — Villiform teeth in the jaws, on the vomer and 

 palatines ; none on the tongue. 



Fins. — The first dorsal originates a little in advance of 

 the opercular margin : the first spine is small and applied to 

 the second, which is shorter than the fourth : the third is 

 the longest, one-half the length of the head : the first ray is 

 one-half longer than the longest spine ; the anal has a long 

 oase arising in advance and continued posterior to the second 

 dorsal ; its second spine is higher than that of this fin : the 

 pectoral is long, extending to the fourteenth scale of the 

 lateral line : the ventral is placed almost wholly in advance 

 of the pectoral, it reaches to between the vent and the anal
