It may be well to mention that when this handsome species is 
mounted in balsam, or prepared in any way which causes the thin 
chitin of the dorsal shield to become semi-transparent, the thick and 
elaborately formed supporting ridges situate on the inner (under) 
surface of the shield show through and give the creature a totally 
different appearance ; so that it might easily be mistaken for a different 
species. 
Found in mo3s, generally distributed in England and not un- 
common, but solitary.

The synonymy of this species is curious ; Canestrini and Fanzago 
in 1877 called it Trachynotus troguloides , considering it to be the 
Argas troguloides of Gervais.* Canestrini subsequently abandoned 
this idea and in July 1884 in the above-named joint paper by Canes- 
trini and Berlese it is named Uropoda lamellosa , a name which 
Canestrini adheres to in 1885 ; but Berlese in his 4 Acari &c. Ital./ 
July 1884, and again in 1892, calls it Uropoda laminosa without 
saying why he alters the name. 
This species was found by Canestrini under stones near Trent 
prior to 1877 ; the only existing specimens which I know of have, 
until lately, been his two or three type specimens. In the autumn of 
1892 I found a considerable number of specimens of a Uropoda closely 
resembling Canestrini’s and Berlese’s figures and descriptions in the 
nests of Formica fusca near the Land’s End, Cornwall. Prof. Canes- 
trini was kind enough to compare some of these with his type speci- 
mens, and he informs me that they are identical. I had not felt quite
