36 THE SCOTTISH NATURALIST 



1916, p. 64). So far as I am aware, the present is the first 

 record of it from Scotland. 



I may add that I found Trichoniscus pygmczus in cracks in 

 weathered rocks at Gullane Point, East Lothian, on 5th June 

 191 3. Specimens taken by Mr Bagnall and myself in 

 Edinburgh and its immediate vicinity were recorded by him 

 in the February 1913 number of this magazine. 



The Spawn of the Lug worm. In spite of the fact that 

 Lugworms occur in hundreds, and often in thousands, on almost 

 every stretch of muddy sand on the coasts of Europe, and of the 

 fact that time and again search has been made by the most 

 competent observers, the confession has to be made that the 

 egg-masses of the Lugworm have never been recognised. Hence 

 much interest attaches to the observations of Dr H. C. Williamson 

 (Journal of Zoological Research, October 191 6) on what he takes 

 to be the spawning of specimens of Arenicola kept in confinement. 

 After the Lugworms had been retained in their box of sand, supplied 

 with running sea-water for a fortnight, a green gelatinous capsule 

 containing green eggs was found attached to the glass. Three other 

 similar capsules were laid in the course of a month. The experi- 

 ment, unfortunately, was not kept entirely free from chances of 

 error, so that it can hardly be accepted as conclusively showing that 

 any of those green gooseberry-like masses of ova which have so long 

 been a puzzle to the shore-naturalist are the egg-capsules of the 

 common Lugworm.

Hellicella caperata at Inverugie. In May 1892 the Rev. 

 Dr George Gordon sent me three small specimens from Inverugie, 

 in Elginshire, which I placed on record for Aberdeenshire North 

 in a note in the Annals of Scottish Natural History for October 

 1892, p. 238, but it was the Elginshire, not the Aberdeenshire, 

 place of that name. W. Denison Roebuck. 



Leucochloridium macrostomum (Rud.),a Trematode new 

 to Britain. In the Glasgow Naturalist, vol. viii. p. 43, three 

 specimens of this Trematode are recorded by Mr J. Ritchie, jun., 

 from the intestine of a Great Grey Shrike {Lanius excubitor) taken 

 in Ayrshire in Dec. 19 15. This parasite is stated to have hitherto 

 been recorded only from Germany, but Mr Ritchie is of opinion that 

 it may have been overlooked in this country, as he obtained five 

 examples in the rectum of the Starling (Sturnus vulgaris) in 

 November 1915.
