SOME NEW OR LITTLE-KNOWN AUSTRALIAN FISHES.— OGILBY. 121 



of the body and one fourth more than that of the head; least depth of caudal 

 peduncle a little less than its length and 3-5 in the depth of the body. Upper 

 profile of head and nape evenly rounded, with a scarcely perceptible emargina- 

 tion above the posterior half of the eye. The occiput and nape moderately 

 keeled; head a little longer than deep, 3-05 in the length of the body. Snout 

 blunt, with gently rounded profile, its length 2-5 in that of the head; nostrils 

 small and approximate, the posterior horizontally the anterior vertically oval, 

 the latter valvular, its distance from the eye 2-5 in that from the tip of the 

 snout. Eye moderate, its diameter 34 in the length of the head and 1-33 in 

 that of the snout ; interorbital region convex, its width a little less than the eye- 

 diameter and 3-6 in the length of the head. Upper jaw slightly the longer; 

 maxillary extending to below the anterior border of the eye, its length 3 in 

 that of the head. Depth of preorbital 145 in the eye-diameter, which is 1-3 

 in the depth of the cheek. Angle of preopercle broadly rounded and feebly 

 denticulate, the hinder limb more strongly, evenly, and closely armed, the 

 lower entire ; opercle with a short, stout, concealed spine ; post-temporal serrated. 



Scale formula 14/f§/26; 1.1. tubes 55. Many of the scales on the 

 tail, especially those near the lateral line, provided with several squamulae. 

 Head, except the snout in front of the nostrils, the lips, and the mandibles 

 scaly, the opercular scales largest; three pair of open pores on the lower jaw 

 inferiorly. Spinous dorsal with a low scaly sheath ; soft dorsal and anal with 

 a broad basal scaly band and the rays scaly nearly to the tip. 



Dorsal fin xii 20, originating above the latter half of the opercle ; spinous 

 dorsal with rounded outline; spines moderate, the first 1-6 in the second and 

 2-3 in the fourth and longest, which is 2-25 in the length of the head and but 

 little longer than the adjacent spines ; thence it decreases gradually to the 

 last, which is a little shorter than the penultimate and 1-25 in the fourth : 

 soft dorsal a little longer than the spinous, with gently rounded outline, the 

 middle rays longest, scarcely longer than the fourth spine. Caudal emar- 

 ginate, the middle rays 1-33 in the upper lobe, which is 3-85 in the body- 

 length. Anal iii 7, originating below the eighth dorsal ray, the second spine 

 stronger and slightly longer than the third, 245 in the length of the head and 

 14 in the second and longest ray, which considerably exceeds the height of 

 the soft dorsal. Pectoral short and pointed, extending to below the penulti- 

 mate dorsal spine, its length 1-5 in that of the head. Ventral pointed, longer 

 than the pectoral, 1-33 in the length of the head; outer ray longest, reaching 

 the vent. 



Gill-rakers short and stout, 12-J-20, the longest 4 in the eye-diameter, 

 and about one third of the longest fringes. Vent five sevenths of an eye- 

 diameter in advance of the anal fin.
