details I am able to supply are abundant to show how widely 
the new species differs from Benham’s type. It may be well 
to place the essential points side by side.

In the related genus Benhamia, we find species differing in 
length from 16 mm. (in B. curta) to 540 mm. (in B. rosea), and 
we may therefore expect Tvigaster to have a similar range. 
On account of the small size of the species here described, I 
propose to name it Tvigaster minima. Other species new to 
science will be described in a later contribution. Meanwhile 
I earnestly solicit the co-operation of collectors.

In the November Geological Magazine, Dr. Lewis Moysey describes 
and figures some arthropods from the Derbyshire and Nottinghamshire 
coalfield, including Leata trigonioides sp. nov. 
In The Mineralogical Magazine, No. 74, Mr. F. H. Butler has a paper 
on ‘ The Brecciation of Mineral-veins,’ in which he figures and describes 
examples from the Isle of Man, Grassington in Yorkshire, and ‘Allenheads 
in Northumberland. In the same journal the Rev. Mark Fletcher figures 
and describes some artificially produced crystals of Gypsum, from Burton- 
on-Trent. 
With the new volume the Annals of Scottish Natural History will appear 
monthly, instead of quarterly, and will be devoted exclusively to zoology. 
The last part of the old series (No. 80) contains a report on Scot- 
tish ornithology for 1910, the Hydroid Fauna of the West of Scotland, the 
Freshwater Rhizopoda and Heliozoa of Scotland, and the distribution of 
Goodyeva vepens. 
In the Jouyval of Botany, Major Wolley-Dod describes a rose to which 
he gives the name Rosa Margerisont. He writes: ‘ Reluctant though I 
have been to name any new form, especially one of which the parentage 
is doubtful, I think this form is sufficiently distinct to deserve a name, 
and its finder tells me there are several bushes.’ The finder was Mr. 
Samuel Margerison of Calverley, who obtained the plant in Upper Wharfe- 
dale. 
In The Zoologist (No. 844), Mr. F. J. Stubbs has some interesting 
observations on the Nocturnal Habits of the Redwing; Mr. J. M. Charlton 
describes the birds of the Northumberland coast; Mr. R. Fortune gives 
a spirited reply to the criticisms upon his observations of a variety of 
the Gannet, and adds ‘it seems nowadays to be perfectly useless recording 
any occurrence rare, or differing from the normal, unless one is prepared 
to exhibit the specimen “‘in the flesh ’’ and, although this course may be 
considered correct by “scientific ’’ naturalists, to me, as a “ field ’’ ob- 
server pure and simple, it does not appeal. Otherwise it would have been 
an easy matter to have secured the bird.” With these remarks we heartily 
agree, though we do not remember to have previously met with a ‘ pure ’ 
and ‘simple ’ ornithologist! Mr. R. Warren refers to his transactions with 
a Leeds dealer in birds’ eggs.
