 foot in diameter. 



Monostyla sp. This was the most interesting animal 

 found, and may prove to be a new species. It is a small 

 animal, with flexible lorica, perfectly hyaline, and with a 

 clear, non-pigmented eye. Its most remarkable feature is 

 the very large toe, which is broad, tapering to an acute point, 

 and strongly curved towards the right side, at the same time 

 slightly spirally twisted, so that as it swims the whole animal 

 rotates round its long axis in the manner of a Mastigocerca. 



Echiniscus arctomys. The form of this extremely variable 

 species found in St. Kilda had the triangular median plates 

 rather more distinct than usual. 



The thread-worm and the Desmids could not be specific-

ALIEN PLANTS NEAR EDINBURGH. 

 By JAMES FRASER. 



IN pursuance of the plan projected in the late autumn of 

 1902 and begun in 1903 (the results for which year were 

 published in the " Annals " for April last), I have now to 

 record the result of the observations made by Mr James 

 M'Andrew and myself during 1904, on the "alien" flora of 

 the neighbourhood of Edinburgh. 



To enable the effect on our Flora caused by the intro- 

 duction of so many foreign plants to be easily determined at 

 some future time, the definite localities mentioned in my 

 first paper are closely adhered to and represented by the 

 same numbers in the following list. 



Thus all plants with the figure I attached were found in 

 the same definite, limited area as those with the same figure 

 in my first list ; and so on up to No. 5. But near locality 

 No. i (which may be called Slateford) are several spots ex- 

 tending from near Slateford Railway Station to Hailes 

 Quarry, where a number of new plants have been found. 

 These are marked IA. 



District No 2. (Granton) has this year produced nothing 

 additional, but near it also several new plants were seen : on
