238 Field Notes. 
the short list published in this journal (‘ Nat.’, January 1910, 
p- 29), I place them on record :—Chloroperla grammatica, 
Micromus paganus, Hemerobius nervosus, H. micans, H. mar- 
ginatus, H. stigma, H. subnebulosus, Nemoura meyert, Phry- 
ganea striata, P. obsoleta, Limnophilus nigriceps, L. auricula, 
L. centralis, L. sparsus, Stenophylax permistus, Lepidostoma 
hirtum, Ecclisopteryx guttulata, Drusus annulatus, Wormaldia 
subnigra, Plectrocnemia conspersa, Hydropsyche instabilis, and 
Rhyacophila dorsalis. Of these, perhaps the most interesting 
are Phryganea obsoleta and Limnophilus nigriceps, neither of 
which has as yet been recorded for Yorkshire.—GeEo. T.

MOSSES. 
Tortula vahlii (Schultz) Wiis. in North Lincolnshire.— 
I had the pleasure of gathering this rare English moss, the home 
of which is the Mediterranean region, at the beginning of this 
month, on the banks of the Waltham Beck, in the parish of 
Cleethorpes, a short distance before it emerges into the mouth 
of the Humber. It is confined to a narrow strip on the right 
bank, about a hundred yards long and six feet wide. It is 
growing on the mud dredged from the bottom of the beck. The 
water is here tidal, and an examination of the bank some dis- 
tance above the lock, failed to detect the moss. The left 
bank was also examined without success. Mr. G. Allison, of 
Grimsby, also searched the beck bank, for a mile and a half 
from its source, at the foot of the Lincolnshire Wolds, without 
meeting with it. Its previous distribution in the British 
Isles, so far as recorded, is West Sussex and Surrey in the south, 
West Gloucester and Hereford in the West, and Cambridgeshire. 
This discovery extends its range much further north. Mr. 
W. Ingham, of York, has confirmed my determination of it.—

REVIEWS AND BOOK NOTICES. 
Life of William MacGillivray, by W. MacGillivray (222 pp., John 
Murray, 10/6 net). 
MacGillivray was a grand example of the old type of ‘all round’ 
naturalist, and his name is still a household word, amongst ornithologists. 
He was born in 1796, and died fifty-six years later; consequently the 
present ‘life’ is somewhat tardy, but it is none the less welcome on that 
account. The narrative is a good one, and many besides naturalists will 
benefit from a perusal of these pages. Prof. J. Arthur Thomson con- 
tributes a charming chapter—‘ MacGillivray’s Scientific Work—an 
Appreciation.’ There are reproductions of several of MacGillivray’s 
careful drawings of birds, including that of the Great Auk. On page x. 
the name of Mr. W. P. Pycraft is wrongly spelt.
