preorbital, and being unable to satisfactorily divide up those I have 
examined into the two genera, I prefer to regard Gill’s genus as a 
synonym of Scorpaena. 
The following is a key to the Australian species available to me. 
a. 50-55 rows of scales just below the lateral line. A more or 
less prominent median keel on the anterior portion of 
the interorbital space. cardinalis. 
aa. 45 or fewer rows of scales. 
b. Transverse hollow behind the eyes, distinct but shallow. 
c. Two prominent interorbital ridges ending in spines. 
Third dorsal spine generally longest. cruenta. 
cc. Inteiorbital ridges low, without spines. Fifth dorsal spine 
generally longest. 
d. Head and body with numerous tentacles. hynoensis. 
dd. Flead and body with but few tentacles. var. laotale. 
bb. Transverse hollow very deep. Interorbital ridges almost 
obsolete. sumpttwsa.

This .species, and not S. crnenta, Richardson, is apparently the 
common Red Rock Cod of the Sydney fishermen. I have exam- 
ined the specimens identified by Ogilby, Waite, and Stead as crnenta, 
and regard almost all of them as being cardinalis ; only two small 
ones from Port Jackson being the former species. Mr. Stead in- 
forms me that there is but one common species in the Sydney 
Markets, of which his specimens are representative, so that S. crnenta 
will probably prove to be a rare species here. Besides the two Port 
Jackson specimens, I hav'e examined several others from Tasmania, 
and find that they differ from cardinalis in having much larger 
scales, and in having the interorbital ridges ending in acute spines. 
Gunther' has united S', jacksoniensts, Steindachner, with 
S’, hynoensis, Richardson, but Klunzinger'^ has shown that this is
