152 " ENDEAVOUR " SCIENTIFIC results. 



Origin of the first dorsal just behind the end of the head : the 

 anterior spine is well developed and the third is the highest. The 

 rays are lower than the longest spine and are subequal in length. 

 Anal beginning and ending behind the soft dorsal ; its rays are 

 lower than those of that tin and gradnally increase in length to 

 the penultimate one. Caudal rounded. Ventrals reaching to the 

 base of the second anal ray ; the spine is weak and the inner ray 

 is simple. Pectoral broadly rounded and reaching to beyond the 

 middle of the first dorsal fin. 



Colour. — Upper surface blackish or brown, sharply separated 

 from the light colour of the lower surface on the sides of the head 

 and body. Seven rather distinct bands cross the back, of which 

 three correspond with the first dorsal, three with the second, 

 and one is on the caudal peduucle. The lower jaw, cheeks and 

 sides of the body are marked with striking brown spots of which 

 the most prominent forms a band below the eye. All the fins are 

 variegated with brown and white but the dorsal and caudal are 

 not crossed by fine black lines ; the basal half of the first dorsal 

 transparent, the outer portion blackish. 



It is with much hesitation that I venture to supply this species 

 with a new name. It is closely allied to several species including 

 1. japonicus, Tilesius, and I. qiioyi, Bleeker, but apparently differs 

 from all in the relative sizes of the eye and the snout, and in the 

 colour marking. It may be at once distinguished from 

 1. tentaculatus, Ruppell, of which I have a specimen for com- 

 parison, by its much larger eye, while it differs from I. nematoph- 

 thaliuus, Gunther, in having a longer snout, but no 

 orbital tentacle and in lacking the characteristic black lines of 

 the dorsal and caudal fins. 



Locs. — Described from three specimens 148-295 mm. long, 

 of which two are from Port Darwin, and the other is from 

 Mapoon, Gulf of Carpentaria. One of these is the specimen 

 which Macleay identified as Platycephalus japonicus.
