margins and are larger than the body scales ; there are sixteen rows in 

 front of the first dorsal. A mucigerous canal is present above the eye, 

 which defines a patch of sapraciliary scales ; two others extend across the 

 cheek, but the remainder, including the parietal groove, are hidden beneath 

 the scales. Preopercular mai'gin not free, almost completely hidden by 

 the scales ; an open pore near its angle. Eye rather small,- lateral, and 

 situated Avithin the anterior third of the head ; it is close to the upper 

 profile. Interorbital space very broad and flat. Snout broadly rounded, 

 with a knob formed by the posterior premaxillary processes ; mandible 

 projecting, the symphysis angular. Mouth oblique, the maxilla reaching 

 to below the anterior third of the eye. Nostrils well separated, the 

 anterior in a low tube near the lip, the posterior a simple opening 

 near the eye. Each jaw with a band of villiform teeth, and an outer 

 row of stronger ones. Tongue broad, subtruncate and free anteriorly. 

 Gill-openings extending forward almost to below the middle of the 

 preoperculum, the space separating them wider than the eye. Exposed 

 edge of the shoulder-girdle forming a smooth curved ridge ; a sharp 

 angle at its junction with the lower margin of the gill-opening. 



Body robust, subcylindrical anteriorly, compressed posteriorly. The 

 scales are large and mostly ctenoid, but are cycloid on the breast and base 

 of the pectoral ; they extend up between the bases of the pectoral and 

 caudal rays. Genital papilla large and broadly rounded, with fimbriate 

 edges. 



First dorsal commencing above the hinder half of the pectoral, its 

 margin rounded ; the third spine is longest but does not reach the second 

 dorsal when adpressed. Second dorsal somewhat rounded, the seventh 

 ray longest, and reaching about two-thirds of its distance from the hypural 

 joint. Anal of similar form to the second dorsal, its origin and termination 

 a little behind those of that fin. Pectoral rounded, the median raj's 

 almost reaching the vertical of the interspace between the two dorsals. 

 Ventrals widely separated, the fourth I'ays longest, and reaching about 

 three-fourths of their distance from the vent. Caudal broadly rounded. 



Colour. — Brown above, after long preservation, white below. Two 

 .dark bars extend obliquely downward from the eye to the operculum, and 

 a third crosses the operculum to the pectoral base ; this last has a light 

 patch on its upper portion, and there is a dark bar, followed by a lighter 

 one, at the bases of the rays. The sides of the body have indications of 

 several longitudinal stripes. The fins are dark in colour, and the dorsals, 

 anal, and ventrals have each a broad light margin. 



Described from a specimen 284 mm. long, which is one of the cotypes 

 of Eleutn's plaiiiccps, Macleay (=2?. ajjordcepltaliiti, Macleay). It clearly 

 shows the cephalic coloui'-markings which were said to be wanting by 

 Macleay, but it seems that tliese dark bars are sometimes more pronounced 

 in old preserved specimens than in those which are fresher. 



Idriititji. — We have compared this example with a specimen from the 

 Malay Archipelago, which was leceived from Dr. F. Day as 0. ujioi-uc, and 

 find the two similar in all details.
