270 Field Notes. 



has made the first advances. A detail that I cannot explain 

 is that females taken in cop. are nearly always very wasted. 

 Possibly they are on the wing for some time before copulation 

 takes place, though this is not the custom with most moths. 

 In my experience one never sees the female except in cop. or 

 during the preliminary overtures. Perhaps she pairs more 

 than once and between times flies out of sight among the 

 bracken, while depositing the fertilized ova. Thus she would 

 come to subsequent pairings with damaged wings. I have 

 observed the pairing of no other species of Hepialus except 

 H. lupiilinns, the males of which seek the females in the normal 

 way, as described by Mr. Morley. Judging from character of 

 flight alone, I should say that H. sylvinus and //. fusco- 

 nehulosa follow the example of lupulinus ; H. hiimuli that of 

 hectus.—'U.. Douglas Smart, Major, R.A.M.C.

 AMPHIBIANS. 

 Palmated Newt {Aiolge palmata) in Westmorland — 

 Little seems to be known of the distribution of this Newt in the 

 Lake District, and it may be well to record its occurrence in 

 Patterdale. It was abundant last June in a shallow reservoir 

 choked with Myriophyllum on the wooded hill behind Patterdale 

 Hall. — Chas. Oldham, Berkhamsted, Herts.

FUNGI. 

 Polyporus Rostkovii in S E. Yorks. — I have just received 

 from Mr. John Foxton, Benningholme Hall, Hull, a tine specimen 

 of Polyporus Rostkovii, 12 ins. high and 10 ins. diam. across 

 top of pileus, this plant differs from P. squamosus in having 

 a central stem. The pileus usually infundibuliform, thin and 

 smooth [i.e., not covered with scales), larger spores (i6/a X ^p) 

 and the stem abruptly black. The spores measured I4-I5|W x 

 5/^., but as Mr. A. D. Cotton of Kew has recently pointed out, 

 the later shed spores in the basidiomycetes are slightly smaller 

 than the earlier ones, and this should be borne in mind when 

 spore measurement is a deciding factor. The spores of P. 

 squamosus measure ii-12{j. x 5/^. I do not think P. Rostkovii has 

 been previously recorded for vice-county S.E. — W. N. Cheesman. 



The Fisheries of the North Sea, by Neal Green. London : Methuen 

 & Co., 1 78 pp., 4/6 net. The publishers say : ' This Httle book is important 

 on account of the increasing value and potentialities of the fishing industry 

 in the North Sea. The author also describes the fisheries of Great Britain, 

 Scandinavia, Germany, France, Russia and America." The author is 

 practical and has made good use of the work of Sir John Murray, the Re- 

 ports of the Fishery Board of Scotland, the French work on Fisheries by 

 M. Herubel, and James Johnstone's Marine Biological Investigations. 

 There is an interesting chapter on ' The Migration of Fish,' and an ex- 

 cellent map.
