134 ' ENDEAVOUR " SCIENTIFIC RESULTS. 



Two co-type", of Caranx compressus are in the Australian 

 Museum collection, but the types appear to have been lost. 

 They are quite similar to the specimen described above, but 

 they differ from Macleay's description in having fewer anal 

 rays, which, together with those of the dorsal, are elongate 

 in both examples ; the sharp ridge on the head referred to 

 by Macleay is only caused by the flesh drying upon the 

 cranial crest, and is not evident in the well-preserved Western 

 Australian specimen. 



Loc. Port Hedland, north-western Australia. The type 

 of C. radiatus was taken at Rockingham Bay, Queensland, 

 and Kent has recognised the species both in Queensland and 

 Western Australia. The specimens identified as C. com- 

 pressus were taken in the lower portion of the Burdekin 

 River, Queensland.

D. viii., i./18-19 ; A. ii., i./18 ; P. 19 ; V. i. 5 ; C. 17. 

 Height before the second dorsal fin almost half the length 

 from the premaxillary symphysis to the end of the middle 

 caudal rays ; head 3-5 in the same. Eye almost three in 

 the head. 



Body elevated, compressed, covered with minute scales 

 which extend forward below to a line from behind the ventrals 

 to the pectorals, leaving the breast naked. Lateral line 

 arched anteriorly, becoming straight below the middle of 

 the soft dorsal fin ; straight portion 1|-1J in the length of 

 the curve. There are thirty-four to thirty-eight scales on 

 the straight portion of the lateral line, of which about 

 twenty-five are more or less keeled and acute ; they are 

 broadest on the caudal peduncle, though their greatest 

 breadth is less than half its depth. Maxillary reaching to or 

 just beyond the anterior margin of the pupil ; it is dilated 

 distally, being almost half as wide as the eye. Preorbital 

 rather broad, about two-thirds the width of the eye. Lower 

 jaw longer than the upper, the chin prominent.
