DESCRIPTION OF BALLIA. 191 
into account the very slight attention hitherto paid by travel- 
lers to the Cryptogamia, but especially the Algz, we may ex- 
pect that when these tribes come to be more carefully looked 
after, future observers will detect it, wherever there is land, at 
a latitude of from 40° to 50° south; and. we may, I trust, 
confidently look to receive it from the Southern Island of 
New Zealand, if not from South Shetland itself, on the return 
of the Antarctic expedition of Capt. Ross. 
The following are its generic and specific characters. ‘The 
generic name is bestowed in honour of Miss ANNE E. BALL* 
of Youghal, a most successful and zealous algologist, who has 
added numerous new species to the Irish Flora, among which 
is the rare Sporochnus Cabrere.
