regard to the lower lip. In a note made from a living specimen, I find the 

 following : — " The flower is compressed, flattened, the upper lip prolonged 

 and projecting in front, the palate has four lines of hairs and four protuber- 

 ances, compressed, thickened, ragged, and covered by the four median lobes 

 of the lower lip." 



The above monstrosity was observed in the neighbourhood of Ghent in 

 1864. 



I have seen several plants of Linaria vulgaris in which the tube of the 

 corolla had thrown out narrow petalloid processes (fig. 1 — 3. J of from six to 

 ten millimetres (one-fifth to four-fifths of an inch) in length. 



V. Ornithogalum sulfureum, M. and K. 

 (Torsion.) 



A floriferous stem of this liliaceous plant, gathered last year near 

 Eochefort (Province de Namur) was affected by torsion for a length of 

 fifteen centimetres (five and three-quarter inches) . The torsion occupied the 

 middle portion of the stem and was also slightly perceptible just beneath 

 the fruit. At the two extremities of the twisted portion, the turns of the spire 

 were open, but for the length of a decimetre (four inches) they were close- 

 pressed.

At page 169 of the Naturalist appears a list of Norfolk Diurni and 

 Nocturni, by the Eev. T. H. Marsh, that are recorded as not being mentioned 

 in my previous notes on Norfolk Entomology. The list enumer- 

 ates forty-eight species, twenty-nine of which, however, will be found 

 included in my notes. (See NaturalistY o\. I. pages 338 and 373 and Vol. 

 II. page 126.) The Eev. T. H. Marsh mentions T. qiiercussmd L. ^gon as 

 common at Cawston, which I had mentioned as rare and uncommon ; my first 

 notes as I then explained were chiefly confined to the outskirts of Norwich.

Argynnis Lathonia. A most splendid example of this rare species was 

 captured by Mr. John Perry, at Plumstead, near Norwich, on the 2nd of
