1022 DESCRIPTIONS OF TWO NEW FISHES FROM PORT JACKSON, 



second by an appreciable interspace. In the first and second 

 dorsal fins the rays are simple, but in the third all are ai'ticulated, 

 as also are those of the anal fin with the exception of the first, 

 which is simple : the middle pectoral rays are the longest, slightly 

 longer than the head : caudal fin rounded. The lateral line is 

 interrupted opposite the termination of the second dorsal fin. 

 Colors — red; the head is much darker than the body; Ijase of 

 the pectoral fin dark bluish-black; many of the scales, especially 

 those above the lateral line, with a transverse dusky streak. A 

 conspicuous black band round the free part of the tail. Dorsal 

 fins, especially the first and second, dusky. 



Two examples of this pretty little fish, the larger of which is 

 jnst an inch and a half in length, were obtained early in the 

 present month beneath stones between tidemarks at Yaucluse by 

 Mr. Edward Mcintosh, who brought them in a fresh state to the 

 Museum. 



CONGROMURiENA LONGICAUDA, Sp.nOV. 



D. 178. A. IIG. C. 10. 



Length of the head two and a half in the distance between the 

 end of the snout and the vent; length of the trunk five-eighths of 

 that of the tail. The cleft of the mouth is slightly oblique, it 

 extends backwards to beneath the anterior third of the orbit, and 

 the distance between it and the tip of the snout is two and four- 

 fifths of the length of the head. The eye is of moderate size, its 

 diameter being contained five and a quarter times in the length of 

 the head, and one and a half in that of the snout; the boiiy intei- 

 orbital space is flat and narrow, three-eighths of the diameter of 

 the eye; the upper jaw extends considerably beyond the lower, 

 and its upper profile is slightly convex. The lips are thin. Teeth 

 in the jaws in several rows, the outer one of which is acute, those 

 behind them being obtuse or even granulose; vomerine teeth 

 extending backwards fully two-thirds of the length of the maxil- 

 lary band, in about six rows and granulose. The dorsal fin com- 

 mences opposite the middle of the pectoral, which is one-third of
