closely approximating in their anterior two-tliirds. Mouth arched' 

 teeth small, in about 90/80 rows ; lower jaw with a central 

 depression, on each side of which the teeth are much longer than 

 elsewhere. A row of short depressed spines along the median 

 line of the back, continued between the dorsals ; a few short 

 blunt spines on the shoulders, and at the upper anterior and 

 posterior angles of the orbits, and a pair on the tip of the snout 

 above. Skin of the lower surface of the rostrum with minute 

 spines pointing backwards ; a similar patch on the anterior angles 

 of the pectorals above and below ; remainder of the cuticle 

 smooth. 



Colors . Yellowish-brown above ; dirty-white below. 



This is the common Rhinohatus of the New South Wales coast, 

 and is found at least as far north as Cape York, where its range 

 overlaps that of R. granulatus, as is proved by a specimen of the 

 latter being contained in the same bottle with several of the 

 former in the Macleay Museum, and all labelled from the above- 

 mentioned locality. 



Rhynchobatus djbddensis. (Forsk). 



This fine species seems to be moderately common in the 

 neighbourhood of Port Jackson, but though differing so plainly 

 from Rhhiobatics, has nevertheless been somehow confounded with 

 the common shovel-nosed Eay, described above. The Australian 

 Museum possesses a stuffed specimen from the harbour, which 

 measures fully seven feet long. 



TiENIURA LYMMA. (Forsk). 



As mentioned previously there is in the Museum an authenti- 

 cated example from Cape York.
