POTTER : SANDERLING IN YORKSHIRE IN JUNE. 143 
the list itself is a mere string of names. No localities being given, 
the reader has perforce to conjecture the precise habitat in the Tees 
basin of such forms as Zimax flavus, Helix pygmea, a lapicida, 
lamellata, and Limnara stagnalis var. albida, which are among the 
more interesting of the fifty-nine species enumerated. pak looks 
in vain for such characteristic shells as the large, trochoid 
H. arbustorum and the extremely small H. hortensis which occur in 
many places between Croft Spa and Gainford, and C. perversa var. 
dudia, which is plentiful on both banks of the river between Pierce- 
bridge and Barnard Castle. The list is so manifestly incomplete as 
to be quite useless for purposes of comparison. Had the authors 
taken the trouble to consult Dixon and Watson's ‘ Descriptive 
Manual of British Land and Freshwater Shells,’ which was published 
at Darlington in 1858, they would have found records of Pisidium 
nitidum (near Darlington), Helix cantiana (banks of the Tees), 
Hf. granulata (Middleton-One-Row), and Cecilioides acicula 
(Rejectamenta of Tees, Middlesbrough). No mention is made of 
the following species, which have been recorded in ‘The Naturalist’ 
during the last twelve years :—Arion subfuscus (Middleton in-Tees- 
dale), A. minimus (Rokeby), A. circumscripitus (Middleton-in- 
Teesdale), Amadia gagates and A. sowerbyi (Middlesbrough), Zimax 
marginatus (Middleton-in-Teesdale and Rokeby), Vitrina pellucida 
(Rokeby), Ayalinia pura and #H. crystallina (Rokeby), Helix 
«uleata (Barnard Castle), and Balea perversa (Rokeby). To these 
lington), Pisidium hensimvanum and P. fontinale (Cockerton), 
P. fontinale var. cinerea (Winston and Heighin 3 ton), P. pusillum 
(Cockerton, Barnard Castle, and Hell-kettles near Darlington), and 
P. milium ( Hell-kettles)—C. OLDHAM. 
NOTE—ORNITHOLOG Y. 
Sanderling in Yorkshire I think the occurrence of one of these birds 
on the English coast in summer is snfficient ¢ mie to be worth rec Pagan A friend 
be so f. mn? It may appear 
relevant and trivial to add that when I was at Spurn on June 7th, 1893, my 
iend met me there and said he would show me a nest of four small eggs which 
he had found a few ibed 
never seen any like them before or since.—
