FISHES. MCCULLOCH. 135 



Anterior dorsal and anal rays greatly produced, the former 

 reaching the end of the fin or beyond the tips of the middle 

 caudal rays, and the latter extending to or beyond the base 

 of the caudal. Pectoral reaching across the curve of the 

 lateral line. 



Colour. Silvery, with traces of four or five broad darker 

 cross-bars. A dark opercular spot. Anterior margins of 

 dorsal spines and the first ray black ; the remaining fins 

 colourless. 



Two specimens 130-137 mm. long from the premaxillary 

 symphyses to the end of the middle caudal rays, only differ 

 in the relative lengths of the dorsal and anal rays ; the 

 anterior profile is also slightly more arched in one than in 

 the other. 



These specimens do not quite agree with the description 

 of C. altissimus, but it must be noted that Jordan and Seale's 

 description and figure differ in several details. They count 

 twenty-one anal rays, but their figure only shows nineteen ; 

 the maxillary only reaches the anterior orbital margin 

 according to the description, but in the figure it extends to 

 below the pupil. The ventral fins are somewhat longer than 

 in my specimens, and the anterior dorsal and anal rays were 

 damaged in the types, so that it is not known whether they 

 were produced as in the specimens described above. 1 



The fish figured by Cuvier and Valenciennes as C. cirrhosus 

 was evidently very similar to the specimens referred to here ; 

 the figure shows the preorbital bone as somewhat narrower 

 and the anterior profile less rounded than in my specimens, 

 but in all other details it agrees very well with them. C. 

 altissimus differs from the closely allied C. aurochs, Ogilby, 

 in having the preorbital bone broader, and the straight 

 portion of the lateral line much shorter ; the anterior anal 

 ray is also more produced and filamentous. 



Loc. Southern Queensland ; the exact locality is un- 

 known. 



1. C. altissimus has been recorded from Manila by Jordan and Richardson 

 (Check-list Fish. Philippine Is., 1910, p. 20). A local specimen is in the 

 collection of the Bureau of Science, Marila, which Dr. Alvin Scale has 

 examined for me. He counts ii. i. 19 rays in the anal fin; the longest 

 dorsal ray is less than a fifth of the total length of the fish, and that of the 

 anal is still shorter.
