MOLLUSOA — IIKDLKV. .'57D 



.similar small sjiincs. 'riic last whorl has one, the others two, 

 intervarioeal tubiMvles. The whole surfaee is overrun l>y close, 

 spiral, stjuairiose threails, whieh mulliply \)y intercalation, and 

 become Hner on the last whorl. I'rotoconch smooth, elevated, 

 two-whorled. Aperture round, posteriorly with a tubercle 

 followed by a deep notch, outer lip advanced beyond the varix, 

 crenulated with double denticules on the inner edge. Columella 

 broad, arched, its edge projecting. Canal long, upcurved, slit 

 narrow. Length, 5(3 mm. ; breadth (without the spines) 2'6 mm. 



Murex cerviconiis, Lamarck, was recorded by Brazier* as taken 

 by Messrs. H. Prince and T. Haylock oil" Sydney Heads in 90 

 fathoms. The specimen referred to is now in the Australian 

 Museum, and certainly belongs to M. damlcornis. The only 

 other mention of .\f. cerviconiis on our coastf no doubt refers also 

 to this species. Murex cerviconiis ought, thei'efore, to be erased 

 from the list of New South Wales Mollusca, and M. damicornis 

 substituted for it. 



The novelty may be classified as intermediate between M. 

 axicornis, Lamarck, and M. recticornis, Martens. 



Dredged in 49-50 fathoms off Coogee; in 19-20 fathoms in the 

 Shoalhaven Bight; and in 63-75 fathoms off Port Kembla.

Station 55. 



Mr. J. H. Gatliffi prefers to call this species Murex abortivus, 

 Perry. To my mind the figure of that indicates a .species of a 

 different group of Murex. 



One specimen from 11-15 fathoms off the Crookhaven River.
