the — ys the upper lip. The lobe of the lower lip is rarely 
notched as in bifida. The corolla is so short and so inwardly re- 
flexed that it stands well ‘nti the calyx-teeth, which are stiff and 
very sharp- pointed when dry. In har arvesting in ‘‘the good old 
times”’ before the advent of the “self-binder,’”’ this form of ‘ the 
swcstedl nettle” was locally known as ‘‘the venom-nettle,” from 
poisoning the hands of ‘the sheaf-tiers.”’ It is not easily dis- 
fingtiahed in the herbarium. The flowers of various species of 
Galeopsis are much eaten by the larve of an insect in Lincolnshire, 
and it is no easy matter to obtain perfect herbarium specimens, 
The nymph or imago, however, I have never been able to obtain 
for identification. Thinking that ‘‘the venom-nettle’’ forms were 
galled plants, unable properly to develop, I did not take more than 
passing notice of them for years. I now find, when every specimen 
of the type is ruined by larve in drying, the form referred to here 
is quite free from insect pests. 
other form of G. Tetrahit, from arable blown sand, I men- 
tioned in The Naturalist, 1896, p.181. It was sent to me as Nepeta 
Cataria, and yee the flowers were wonderfully like a large 
orm of t species; being white, with the upper lip tinged with 
yellow on the outer surface, and pink spots on the inner surface o 
the lower lip. Flowers nearer the shape of G. versicolor, but not 
quite so large. Though there was some quantity found of it at the 
time, it has never been seen since, apa frequently hunted for 
on the old spot. Can it have been a me e floral monstrosity? It 
certainly was a thing of beauty, and scientifically of interest, " 
it seemed a half-way form between Tetrahit and versicolor, Has 
ever been met with elsewhere ?

By Grorce Murray, F.R.S. 
The fine collection of Diatoms of the late Thomas Comber, of 
Parkgate, Cheshire, was presented to the Department by his widow. 
It consists of 2926 microscope-slides, 2225 photographic negatives 
and lantern-slides, and upwards of 500 photographic prints ; 
28 
MS. notes, and 88 tracts. This carefully elaborated collection forms 
an important addition to the already immense series of Diatomaces 
in the possession of the Department. |
