872 NEW FISHES IN THE QUEENSLAND MUSEUM. 



Amphisile 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 

 length from the snout to the base of the caudal fin. Snout one- 

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

 pectoral from the operculum is thi'ice 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 witli 

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

 broader than high. The humeral does not nearly extend to thf; 

 base of the pectoral. There 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 

 u[)per 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 

 Noosa and not in good condition, but the absence of serrated 

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

 <fec., are in the present state of our knowledge of these remarkable 

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



Heptadecantiius brevipinnis. 

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



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

 times in the total length. Profile of head regulai-ly 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. Tlie 

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

 nearly uniform greenish brown, a little clouded with darker.
