which (see p. 203) is new to science, and another — a species of 
Chondrosteus (see pp. 197-8 and 203) is noteworthy as having 
never before been discovered in any part of the world except Lyme 
Kegis ; and it is indeed owing to the time expended upon such 
matters and to the correct determination of the various species, 
that I have to apologise to my subscribers for having delayed, for 
more than a year, the publication of this work. I hope, however, 
the contents will shew that the time has not been wasted. 
It is probable, from the small number of copies (300 only) 
now issued, that a second edition may ultimately be called for. 
I would therefore ask Zoologists to favour me, from time to 
time, with any further information which they may consider of 
interest.
