Philoscia muscorum (Scopoli). 



Sedgefield (A. M. N.) ; Humbleton Hill, Cleadon, and 

 Carley Hill Quarry near Sunderland, Stocksfield, and Rat- 

 cheugh Crag (G. S. B.). Mr. Bagnall has taken it in a great 

 many localities in our two northern counties. He writes to us 

 " Generally common under stones in hedgerows, and amongst 

 dry grass, vegetable matter, etc. A very dark and almost 

 unicolorous form is found under stones in gardens ; a totally 

 yellow variety in damp moss of waterfalls (Gibside, Durham, 

 and Saltburn, Yorkshire). A number sent to me from the 

 south of England are of a beautiful pink colour, exhibiting no 

 trace of brown. All our Northumberland and Durham speci- 

 mens are much darker than the southern examples, with the 

 exception of the yellow variety ; and none of them exhibit the 

 slightest trace of pink or red in their coloration.'' N.D.

1908. Philoscia Patiencei, Bagnall (R. S.), Ann. and Mag. 

 Nat. Hist., ser. 8, vol. i., pp. 428-451, pi. xviii. 



After describing this small species of Philoscia, which was 

 discovered in large numbers in a hothouse at Kew, Mr. 

 Bagnall writes, " On examining the species something in its 

 general facies appealed to me as being familiar, and I remem- 

 bered a few examples of a puzzling form which I had found 

 with Trichoniscus pygniceus, Sars, in a garden at Winlaton, 

 Co. Durham. This form was entered in my diary for October, 

 1906, and February, 1907, as " Trichoniscus dilaticornis, sp. 

 nov.?" but, as the specimens were undoubtedly immature,
