In the " Recorder's Report " published in the Proceedings of the Conchological 

 Society {Journal of Conchology, April 1912, p. 317), many new county records are 

 given, the only Scottish one being Clausilia bidentata, taken in Orkney in 1907. 



A note is published by K. H. Jones in the April number of the Journal of 

 Conchology (p. 293) on the occurrence of Pisidium lilljeborgi, Clessin, in the island 

 of Arran. Numerous specimens, some of which were of an unusually large size, 

 were taken in September 191 1. 



In a further short instalment of the late G. H. Verrall's paper on "Another 

 Hundred New British Species of Diptera," published in the June number of the 

 Ent. Mo. Mag. (p. 144), Thrypticus polhnosus is described as a new species, and 

 recorded from Aviemore and Nairn, T. fellus is noted as occurring as far north as 

 Nethy Bridge, and Medeterus infumalus, Lw., is mentioned as having been taken 

 by Col. Yerbury in the same locality. 



A. E. J. Carter, in the Ent. Mo. Mag. for June (p. 139), records the occurrence 

 of the Tipulid fly Triogma trisulcata, Schum., in Perthshire. Five specimens were 

 taken on the 8th May, on marshy ground near Blairgowrie. The species was only 

 added to the British list in April, on the evidence of an English specimen. Its 

 occurrence in Scotland is therefore of interest. 



In the conclusion of his paper on " British Odonata in 191 1 " {Entomologist, 

 June 1912, pp. 171-173) W. J. Lucas records several interesting captures made by 

 Col. Yerbury in the north of Scotland. In all some ten species were obtained, the 

 most important being a new race, or perhaps species, of Sympetrum, which is 

 described under the name of nigrescens. A pair were taken at Lochinver in June 

 and July 1911, and it is stated that they exactly resemble two females taken at 

 Stornoway by H. S. Tremlin in 1899. 



Dr Sig Thor (Norway) describes at some length, in the Zoologischer Anzeiger 

 (Bd. xxxix., pp. 529-533, and figs. 95-98), the larva of a Scottish Hydracarid, 

 Lebertia porosa, Sig Thor. The larva of an Irish species, L.insignis, Neuman, is 

 also described in detail. 



In a letter to Nature of 6th June, Dr Thomas J. Jehu, of The University, St 

 Andrews, announces the discovery of fossils (after many months' search) in the 

 Chert and Black Shale Series at Aberfoyle. The specimens have been submitted 

 to Dr Peach, who has recognised among them the casts of Brachiopods apparently 

 belonging to the genera Lingulella and Obolus, also the jaw of an annelid. ,l The 

 evidence, so far as it goes, which is afforded by these fossils, as to the age of the 

 Boundary Fault Series, tends to confirm the view that it is Upper Cambrian, or at 

 any rate Lower Palaeozoic."
