 FROM PORT JACKSON. 



By E. P. Ramsay, L.L.D., F.R.S.E., and J. Douglas-Ogilby. 



Chilodactylus morwong, sp. nov. 



B. VI. D. 19-18/27-29. A. 3/16-17. V. 1/5. P. 8/7. C. 17. 

 L. lat. 55 on body 6 on tail. L. trans. 7/18-19. 



Length of head 420, of caudal fin 4*70, height of body 3*20 in 

 the total length. Eyes — diameter 5 '00 in the length of the 

 head, 2*66 in that of the snout, and 1*20 in that of the interorbital 

 space, which is convex. The upper profile of the head is almost 

 straight to above the posterior margin of the eye, whence it rises 

 with a gentle convexity to the origin of the dorsal fin. The 

 abdominal profile forms a sharp keel as far as the ventral fins. 

 The upper jaw is rather the longer ; the lips fleshy. The maxilla 

 extends about two-thirds of the length of the snout. Teeth— in 

 villiform bands in both jaws, with an outer enlarged row, the 

 teeth composing which are of a conical shape and apart from 

 one another Fins — the dorsal fin is low, the fifth to eighth spines 

 being the longest, and equal to a third of the length of the head ; 

 the notch between the spinous and soft portions slight : the second 

 anal spine is rather longer, but equally as strong as the third : 

 the ventrals do not quite reach to the anus : the second undivided 

 pectoral ray is rather more than a third of the length of the body, 

 and reaches to the fourth anal ray : the caudal is deeply forked. 

 We were unable to detect any pyloric appendages. Colors — grey, 

 darker above, most of the scales having golden reflections, a broad
