Hull: Acari from Birds’ Nests. 399 
Cillibano minor Berl. is a species not too clearly defined, 
but the present identification is, I think, reasonably certain. 
Its usual habitat is among dead leaves, and I have specimens 
from all the northern counties except Lancashire. 
ORIBATES BOOTHIANUS N. SP. 
Length, 530p; greatest breadth, 390p. 
Colour, dark chestnut brown. The cuticle is quite smooth 
and glossy without any hairs. Chaetotaxy of legs and cephal- 
othorax normal, but the bristles of the latter are shorter and 
weaker than usual. 
Cephalothorax rather short, with well-developed but not 
large lamellae, converging rapidly forward where they terminate 
in a very short but acute cusp. Translamella absent. First 
tectopedia normal, but the 
second comparatively large. 
Pseudostigmatic organs 
erect, short, gradually clav- 
ate, the clubbed extremity 
adorned with short straight 
bristles. The tarsus has one 
claw only. 
I have much _ pleasure 
in naming this species in 
y honour of Mr. Booth. It 
belongs to the monodactyle 
group of the genus Ovzbates 
Oribates boothianus. (Ovibata Michael). Its near- 
Body (without legs), and pseudo-stigmatic est ally is perhaps O. fur- 
organ: catus P.& W.., also described 
from Yorkshire types, by 
Messrs. Pearce and Warburton (P.Z.S., 1905). It is, however, 
much smaller than furcatus, of which I have examples from 
Cumberland and Westmorland, and is readily distinguished 
from all the rest of the group by the erect pectinate pseudo- 
stigmatic organs.

Vol. XV. of The Transactions of the Cumberland and Westmorland 
Antiquarian and Archaeological Society have just been received, and are 
largely occupied by reports of excavations of Roman sites, including a 
report of the ‘Exploration of the Roman Fort at Ambleside,’ by Prof. 
R. G. Collingwood. In this he figures an object described as ‘ of doubtful 
use, shaped at one end like a pair of forceps, and having a hole and slot at 
the other as if to hinge on a transverse metal bar like the beam of a pair 
of scales. It was found in the commandant’s house, room A, lower floor.’ 
We feel sure some mistake must have occurred here as the object is pre- 
cisely similar to a pastry maker’s implement in use in the early part of 
the last century, the ‘ hole and slot’ described in the Transactions being 
for the reception of a rivet for a wheel used to decorate the outside of the 
pastry.
