872 NEW FISHES IN THE QUEENSLAND MUSEUM. 



A.MPHISILE CRISTATA. 



D. 3?/9. A. 14. C. 10. V. 7. P. 11. 



The height of the body is 5, the length of the head l|d in. the 

 I h from the snout to the base of the caudal tin. Snout one- 

 fourth longer than the height of the body. The distance of the 

 pectoral from the operculum is thrice the distance of the latter 

 (i.e., its posterior edge) from the orbit. There are six vertebral 

 shields, the sutures indistinct, simple, and five lateral shields with 

 no suture along the vertebral line. The operculum is very little 

 broader than high. The humeral does not nearly extend to the 

 of the pectoral. Thei'e is no longitudinal groove on the 

 head, the sharp edge of the nostral is continued to the first 

 vertebral shield. The top of the root of the pectoral is on the 

 upper third of the body. The first and second super-abdominal 

 shields are equal in size and as high as broad. The cuirass covers 

 two-thirds of the height of the body and is equal in height to the 

 caudal peduncle. Profile regularly convex from the snout to the 

 caudal. There are three radiating dorsal spines, but the tip of the 

 cuirass being lost its appendages remain to the ascertained. 



Length, 11 inches. A dry specimen picked up on the beach at 

 JS'oosa and not in good condition, but the absence of serrated 

 sutures between the plates, length of the thorax, ridged crown, 

 &c, are in the present state of our knowledge of these remarkable 

 fish, sutiicient to separate it from A. scutata. Linn. 



Heptadecanthus brevi pinnis. 

 D. 17/15. A. 2/14. 



The height of the body is less than 2, the length of the head -i 

 times in the total length. Profile of head regularly subconvex, of 

 nape gibbous. Operculum entire, preoperculum serrated, preorbital 

 finely serrated. The pectorals reach the third scale row from the 

 anal. The lateral line reaches the middle of the soft dorsal. The 

 first ray of the ventral elongated, filiform. Caudal forked. Colour 

 nearly uniform greenish brown, a little clouded with darker.
