342 THE ZOOLOGIST. 



The Greenshank, Totanus glottis, is not included by Mark- 

 wick in his printed Catalogue, but a coloured drawing of it is 

 given in his MS., with the statement that he received the specimen 

 from which he drew the figure on the 9th May, 1786. The 

 drawing shows that the bird was an adult in partial summer 

 plumage. It had probably only just arrived, the 9th May 

 being, as I have observed, the average date of its arrival in 

 spring. 



Markwick's statement (MS. p. 43) that the Kedshank, Totanus 

 calidris, is a solitary bird, being usually seen alone by the sides 

 of marsh ditches, is not correct. In May and June it is to be 

 seen about the marshes in pairs, in autumn in small parties, the 

 old birds accompanied by their young, and in winter often in 

 considerable flocks. The specimen from which Markwick made 

 a drawing was " shot near the seaside on the 29th Dec. 1783." 



I have already pointed out that his Tringa glareola, of which 

 a figure and description are given (Trans. Linn. Soc. vol. i. 

 pp. 128—130) is not the Wood, but the Green Sandpiper, T.och- 

 ropus, and it is clear that he himself subsequently became aware of 

 his mistake. Referring to these two species (MS. p. 48) he says : — 



" A few are to be found in the summer season, such as the Green 

 Sandpiper (T. ochropus), Wood Sandpiper (T. glareola), and Common Sand- 

 piper (T. hypoleucus), which all frequent our fresh-water streams. Three 

 or four of the first of these species, T. ochropus, frequented the river at 

 Horsham, near Cheeseworth, for two years together, and probably bred 

 somewhere in the neighbourhood, though I was not so fortunate as to meet 

 with a proof of it. Their flight was high and swift, very much resembling 

 that of the Common Snipe. The next, or T. glareola, was also killed near 

 a fresh- water stream, and is supposed to be only a variety of the foregoing 

 species. See my description in the first volume of the ' Linnean Society's 

 Transactions ' (p. 128, tab. ii.)." 



Markwick's " Descriptions of three varieties of the Purre or 

 Stint," already referred to as communicated to the Linnean 

 Society on the 7th March, 1797, but not printed, are to be found, 

 with coloured sketches, in his MS. note-book, and it is evident 

 that his observations have reference to three seasonal phases of 

 plumage of the Dunlin, Tringa alplna. 



One of the most interesting of all Markwick's statements in 

 his printed Catalogue is that which relates to the former breeding 

 of the Avocet in Sussex. He remarks (p. 27) : —
