NOTES AND QUERIES 433 



as I have seen them before, but this bird flew right up and perched on 

 the higher branches of the tree, and did so almost with the facility of 

 a Wagtail. The Bay's "Wagtail was very abundant in Chatsworth 

 Park. I also saw a Greater Spotted Woodpecker in the woods 

 behind Chatsworth House. Books this summer have established 

 a small colony of nests, and brought off their young successfully 

 near my residence. The oldest inhabitant does not remember the 

 Book nesting previously in this locality. The Greenshank, Oyster- 

 catcher, Pochard and Golden-Eye, have also been seen in one of the 

 adjoining dales. It is well known that much migratory movements 

 exist even among what are called our resident birds, so I have kept 

 my. eye on a Dunnock * which has one half of its tail quite white. It 

 was here all last winter, and has bred this summer, and still it is 

 here. Has the Yellow Bunting larger clutches in some parts of its 

 British range than here ? It is exceptional to find a clutch in this 

 neighbourhood of four eggs, the more usual number being three. I 

 am sure I have found larger clutches in other parts of England. —

CEUSTACEA. 

 Thia residuus, Herbst. (polita, Leach) in North Wales. — This 

 interesting crab was first taken by Dr. Melville in Galway, Ireland, 

 as recorded by Bell in 1853 — one male and two females with spawn. 

 A further specimen was recorded from Wales by Mr. A. O. Walker 

 in 1885, when one specimen was dredged near Llandudno, and again 

 in 1890. It therefore occasioned me great surprise to find one when 

 digging for shells with my nephew on a small sandbank at Abersoch 

 in August last. The tide was a very low one for that time of year 

 and just on the turn, so we had to work hard at that tide and 

 the following low tides, with the result that we found twenty-six 

 fairly large specimens, and some smaller ones which we did not 

 keep. The largest specimens measure just under three-quarters of 

 an inch in length and a full three-quarters in breadth. The colour 

 was ivory white in all cases, and the two spots when present bright 

 orange. The majority were females, but with no spawn. The 

 species is evidently gregarious, as twice we discovered - two close 

 together, but of the same sex, and though we worked the adjoining 

 sandbanks we failed to find any more. It is possible they came in 

 from deeper water to change their shells, as one was found with the 

 new carapace developed. — E. B. Nevinson (Morland, Cobham, Surrey)
