RIVER BIRDS. 
1. The Sea Pie or Oyster Catcher. Appearing with Lapwing in 
February and March. 
2. The Black-headed Gull. Almost same date. 
3. The Tern. Not appearing till April or May. 
4. The Ring Plover. A few rest on the shingle about Dalmarnock. 
5. The Sandpiper. April; begins to arrive up the river. 
A few of the Lesser Black-backed Gulls are to be seen along the 
banks of the Tay all winter. It is almost certain that they have been 
attracted and kept by the number of salmon that have died from the 
effects of the salmon disease. During the season, I noticed one pair 
that left, but which returned with two more with immature plumage. 
Last year while the volunteers were encamped on a park at the river 
side, gulls of all kinds congregated there, several of which I failed to 
identify. 
The Little Auk, The Guillemot, The Razor Bill, and The Stormy 
Petrel have been found occasionally in the district. 
XXIII.— A Preliminary List of Perthshire Mosses. 
By Robert H. Meldrum. 
(Read loth February, 1898.) 
Lists of Mosses from particular localities in the County of Perth 
have been published on various occasions, but no list for the County 
as a whole has yet appeared. An attempt at such a list is subjoined 
for the purpose of showing what species have been found, and so 
directing attention to those which one would expect to occur, but 
which have not, so far as I know, been yet detected here. 
That I have omitted several species which do occur is certain, 
and I hope that any one possessing information about the occurrence 
of such species will kindly notify me of the fact, and if possible send 
a specimen for the Museum Herbarium. 
That some of the records here given are errors is also certain, but 
this is a more difficult matter to rectify, especially when one has not had 
an opportunity of examining the specimens on which the record was
