HalD. — On rocks in shallow tide-pools, in the shade, at 

 a little above half- tide level. March to July. Spores 

 escape in June. Joppa, near Edinburgh. G. AV. Traill. 



This species belongs to the section Spcirogonicce, in 

 which the fertile cells at first are scattered, solitary, or two 

 or three together, of Kjellman's sub-genus Mclanartlirum, 

 which is characterised by the fertile cells containing very 

 numerous motile bodies, about 2-5 /a. in diameter, so closely 

 packed as to render the cells which contain them opaque. 



Although very closely related to A. albescens, Kjellm., 

 A. Traillii appears to be a fairly well marked species. 



Named in honour of Mr. G. W. Traill, its discoverer, to 

 whom alone is due the credit of having noted that it was 

 different from A. centralis.

I. Effort on Te:\iperature and Vegetation during 

 March 1894. By Robert Lindsay, Curator, 



During the month of March the thermometer was at or 

 below the freezing point on nineteen mornings, indicating 

 collectively for the month 63° of frost, as against 64° for 

 the corresponding month last year. The lowest tempera- 

 tures were registered on the mornings of the 12th, 27° ; 

 16th, 25°; 17th, 24°; 26th, 26°; 27th, 25°. The day 

 temperatures were high, the lowest being 46°, on the 5 th, 

 and the highest 65°, on the 30th. There was a fair 

 amount of bright sunshine, and on the whole the month 

 was a most favourable one. Vegetation generally has 

 made good progress. The leaf-buds of deciduous trees and 

 shrubs are well advanced. Early flowering varieties of 

 Rhododendron, Andromeda, and Bibes are flowering freely.
