maxilla reaches to below the anterior portion of the eye instead of nearly 

 to the middle, and the first dorsal is not lower than the second. They 

 are similar in all details to an Indian example identified by Dr. Day as 

 6r. criniger, which is synonj^mous with B. nebidosus. 



Lors. — We have examined specimens from the following^ localities. 

 Shark Bay, West Australia. Port Darwin, North Australia. Sweers 

 Island, Gulf of Carpentaria ; coll. Hedley. Cape York, North Queensland ; 

 cotypes of (r. festivus. Thursday Island, Torres Strait ; coll. Hedley & 

 McCulloch. Darnley Island, Torres Strait; coll. Dr. J. R. Tosh. New 

 Hebrides. Madras, India ; Dr. Day's collection. 



Distribution. — Red Sea, Zanzibar, and Madagascar, through the 

 Malayan Aichipelago to the Pacific ; Northern Australia. Bleeker^'^ 

 identified a Tasmanian fish as (L criniijer, but this species does not occur 

 so far south.

D. vi/10 ; A. 10 ; P. 17 ; V. i/5 ; C. 13. 30 scales between the axil 

 and the liypural joint, and eleven between the anterior dorsal and anal 

 rays. 



Depth before the ventrals 4-4? in the length to the hypural joint ; 

 head 3'5 in the same. Eye equal to the length of the snout, 3'6 in the 

 head ; interorbital space 2'6 in the eye. Depth of the caudal peduncle 

 2'5 in the head. Breadth before the pectoral bases 1"4 in the depth. 



Head a little deeper than broad, entirely naked. Clieeks and oper- 

 culum with many rows of mucigerous pores, ari'anged as shown in the 

 figure ; large open pores are present on the interorbital space, along the 

 nuchal groove, and around the preopercular border. Ej'es smaller than 

 in li. uehulosus, separated by a narrow interorbital space. Snout obtuse, 

 and broadly rounded ; anterior nostril in a short tube near the upper lip, 

 the posterior a simple opening near the ej^e. Mouth oblique, the maxilla 

 reaching to below the anterior border of the eye ; the mandible slightl}- 

 longer than the upper jaw. A band of villiform teeth in each jaw, and 

 an outer row of enlaiged ones in the premaxillaries, which increase in size 

 backwards ; a small canine on each side of the mandible, between which 

 is an outer enlarged row of teeth. Tongue subtruncate, and free anteri- 

 orly. Gill-openings lateral, separated by a broad isthmus; exposed edge 

 of the shoulder-girdle smooth. 



Body rather stout, compressed, and covered with lai-ge ctenoid scales,
