190 George: Trombidium parcum, n.sp. 
figure gives a good idea of its shape, which, however, is possibly 
somewhat different from that of a mature female. The whole 
body is covered with hairs, or papillae (which are beautifully 
plumose) with the exception of the upper surface of the ros- 
trum, which is bare of hairs ; this is quite unusual, but possibly 
they have been rubbed off, otherwise this may be a very 
important point. The crista is about 0’26mm. long and differs 
somewhat from any I have before seen ; near the upper, and 
thicker part on each side, there is a stigma, and another in the 
skin, about half way down; no stigmatic hairs were observed, 
they were probably rubbed off. 
The palpi have each a secondary small claw on the fourth 
segment. The first leg, which is the longest, is about 0.62 mm. 
long, the terminal article of which is remarkably broad and 
strong. The second leg is about 0.45 mm. long, the third 
0.46 mm. and the fourth 0.56 mm. They are all supplied with 
short hairs. 
It is to be hoped that more mature specimens will hereafter 
be discovered in which the important parts, as the eyes, etc., 
may be investigated; of course a living specimen would be 
invaluable for identification.. There are, I believe, a good 
many varieties of Trombidium, which have not yet been des- 
cribed. They are most beautiful creatures for microscopic 
observation. This specimen was mentioned on page 41 of 
The Naturalist for January, 1916, under the name of ‘ Smaridia 
papillosa’ Herm. This isa mistake, as proved by dissection. 
[Dr. George has kindly presented two slides illustrating 
the anatomical details of this mite, to the Hull Museum, 
where, with the various other specimens he has described 
from time to time, they can be consulted by students.—ED. | 

7O: 

BIRDS. 
Black Terns near Knaresborough.—Lord Mowbray, 
this morning, told me that he had seen two Black Terns flying 
about the bottom lake at Allerton, on Sunday, May 7th. 
They were not there on Monday.—R. FORTUNE. 10/5/16. 
Local Names for Birds.—On May 6th, 1916, I conducted 
the Maltby Rambling Club to Roche Abbey, and learnt that 
the Maltby children speak of a bird called a “ Banky Feather 
Poke.” I do not find this name in the “ Birds of Yorkshire.” 
At Doncaster, the Willow Warbler is named “ Ground Feather 
Poke,” and at Maltby, both Willow Warblers and Chiff-Chaffs 
are common. Probably the name “ Banky Feather Poke ”’ 
is applied to one of those species, and possibly to both of them.—
