188 NOTES AND NEWS. 
Forth area in the one direction, or for Yorkshire in the other, and 
not for Northumberland and Durham. The species which are repre- 
nted by actual local specimens in the Museum collection are 
panel by an asterisk, and—a most important point—their faunal 
status is always indicated by a letter—R, M, S, or C—the signification 
being as follows :— 
Resident ; truly native, and indigenous to the Coast or the 
adjacent Sea, or to the Burns and Rivers. 
Migrant; approaching the Coast or ascending Rivers 
periodically from deep water to spawn 
_ §. Straggler; occurring occasionally on the Coast, a wanderer 
from the North or South, but not resident. 
C. Colonist; introduced artificially, that is, by human agency, 
at an earlier or later period, into rivers, lakes, and ponds, and now 
fully acclimatized. 
otal number of species which Mr. Howse includes in the 
list is 142, as against 155 which are included by Messrs. Clarke and 
Roebuck in their Handbook of the Vertebrate Fauna of Yorkshire 
in 1881, and 125 included by Dr. Parnell, in his Natural History of 
the Fishes of the Firth of Forth, published in 1838. It would be 
interesting, but time forbids, to pursue the comparison further, so as 
to ascertain the relative numbers of resident, migrant, straggler, and 
egy = in each of the three areas in tion. 
ample index is furnished, after which is given the list of 
ede. already referred to. 
ltogether, it is but seldom that we meet with sixty-four pages of 
matter as useful and interesting as that which Mr. Howse has 
furnished, and it may be regarded as a model which cannot be too 
soon adopted by the ichthyologists of other counties within our 
northern area.
