Queen's Park ; while there were forty-two species, and many 

 varieties, in bloom in the same month of last year. This striking 

 contrast may be accounted for by the continuance of severe frost 

 during the whole of December last, while the corresponding month 

 of 1873 was exceptionally mild, thus promoting the flow of sap 

 and stimulating what may be termed premature growth. During 

 February the weather was very cold and dry, consequently few 

 plants flowered. Snowdrops appeared about the 6th, Primulas, 

 Hepaticas, Daphnes, and Saxifraga o^jpositifolia, about the 20th. 

 Evergreen shrubs and grass had sufl'ered more during the previous 

 ten days than during the severe weather of December, when 21" 

 of frost were registered. 



The mean temperature in the Queen's Park in 



December was — Maximum, 34 Minimum, 25 



January, do., 44 do., 35 



February, do., 41 do., 32 



The rainfall in December was 1*77 inches ; January, 5*60 inches; 

 and February, 1*42 inches.

The genus Glauconome, established by Goldfuss, and revised by 

 Lonsdale, is thus characterised by M'Coy (Carb. Foss. Ireland, 

 p. 198):— 



" Stem elongate, oval, laterally branched; obverse bearing longi- 

 tudinal rows of pores; reverse striated." 



The oval form is not universal ; and the omission of any 

 reference to the form of the cells has led to the inclusion, under 

 one generic designation, of forms which should at least rank as 

 sub-genera. We have described (Q. J. Gr. S., vol. xxx., p. 682, 

 pi. 40, figs. 5-11) one species, Glauconome stellipora, characterised 

 by the remarkable regularity of the eight radial spines, which 

 guard the opening of the cells ; in a second group there is 

 invariably a minute orifice beneath each cell aperture, while 

 both spines and accessory orifice are wanting in a third group. 

 Before proceeding to the discussion of these forms, we would 

 remark that our comments, in so far as they alter the determina- 

 tions of our predecessors, are not so much corrections, as in reality
