The Birds of Pembrokeshire. 
birdstuffers. It is not in Mr. Mathias’ list. From its habit of 
running at the base of the cliffs among the rocks, with whose 
tints the colour of its plumage greatly corresponds, this bird may 
easily escape observation, and only a naturalist familiar with its 
habits would be competent to detect it. 
KNOT, Zvinga canutus——An autumn and winter visitor. Flocks of 
Knots appear on the sand flats and oozes at the end of August 
and beginning of September from their breeding station in the 
far north. Mr. Tracy states that they were to be seen 
commonly every autumn near Pembroke. Also on the sands at 
Goodwick, &c. The flocks are foolishly tame when they first 
arrive. 
RUFF, Machetes pugnax.—An occasional autumn visitor; rare. 
Not in any of the lists. This species, once common as a 
resident and nesting bird in the fen districts of England, seems 
to be very rarely obtained in Pembrokeshire, and we are only 
able to include it on the strength of a single specimen that we 
have seen at Cuffern, obtained by the late Mr. John Stokes, 
many years ago from the neighbourhood of Pembroke. It 
may very likely have been shot occasionally without being 
recorded. 
SANDERLING, Cadidris avenavia.—An autumn visitor; scarce ; 
also sometimes seen on its passage northin the spring. The 
Sanderling is occasionally to be seen on the sands in September 
in small flocks, and one or two are sometimes to be found in 
company with the Dunlin and Ring-Plovers. Sir Hugh Owen 
has shot it on the sands at Goodwick. It has been seen on the 
Newgale sands, where a female was shot on June rst, 1857, 
which, Mr. Tracy states, had the ovaries well developed. 
COMMON SANDPIPER, 7Z7ingotdes hypoleucus.—A summet visitor. 
This pretty species, which sometimes goes by the name of the 
“Summer Snipe,” arrives about the middle of April from the
