104 MEMOIBS OF THE QUEENSLAND MUSEUM. 



The above definition is based on two siDecimens 95 and 103 mm. long from 

 Manila, Philippine Islands. The species has been recorded from Torres Strait by- 

 Mac loay as T. trilineatus, and from the Queensland coast by de Vis under the name 

 Autisthes argenteus. The specimen on which the latter name is based is preserved in 

 the Queensland Museum (No. 11/176), and, though stuffed and painted silver, leaves 

 no doubt as to its identity with Therapon puta.

CRESCENT PEPvCH. 



D. xi i 10 ; A. iii 8-9 ; P. 13 ; V. i 5; C. 17. 91-99 scales above the lateral line 

 ))etween its origin and the hypural joint, and 85-95 below it ; 14-15 scales between the 

 lateral line and the middle of the spinous dorsal fin. Cheek-scales in 8-10 rows. 



Proportions of two specimens 108 and 183 mm. long : — Depth 2.6-2.9 in the 

 length to the hypural joint ; head 303-3- 1 in the same. Eye 3-7-4 in the head, subequal 

 to the length of the snout and the interorbital width, Avhich are 3-7-3-8 and 3-5-4 in 

 the head. Fifth dorsal spine 1-5, first dorsal ray 1-7-2-08, and tliird anal spuie 2-7 in 

 the head. 



Body ovate, compressed. Cranium with a few obscure bony ridges posteriorly. 

 Preorbital serrated. Preoperculum denticulate on its hinder and lower margins, \Aith 

 short spines on the roimded angle. Lower opercular spine enlarged, produced beyond 

 the opercular lobe. Suprascapular bone exj^osed, smooth or serrated ; coracoid denti- 

 culate. Fifth dorsal spine longest, much higher than the anterior rays ; the last spine 

 is much longer than the penultimate one. Second and third anal spines subequal. 



Body with three dark longitudinal bands which are curved doA^Tiward ; the 

 first extends from the origin of the spinous dorsal to that of the soft ; the second from 

 the nape to the upper surface of the caudal peduncle, and touching the lateral hne ; 

 the third from the occiput to the middle of the caudal peduncle. Ihe latter extends 

 along the median caudal rays, and there are two oblique bars on either side of it ; the 

 upper lobe of the caudal is also tipped with black. A very large black blotch on the 

 spinous dorsal between the fourth and eighth spines, and a small one may be present on 

 the posterior sjDines ; soft dorsal with two black spots. 



This diagnosis is based on four Australian specimens, 108-183 mm. long. 



Jordan & Thompson {loc. cit.) have recorded differences between specimens 

 from various locahties of the widely distributed T. jarbua, which, they suggest, may 

 represent distinct species. Such material as is available to us beais out their obser- 

 vations, the Austialian specimens having smaller and more numerous scales than 

 (Others from the Pliilippine Islands and Samoa, but in the absence of a good series from 

 several locahties we are unable to add anything to their remarks. As noted by them.
