534 Mr Warburton, Tlie Geographical Distribution , etc. 
From the other localities the following British forms were 
obtained : 
Madagascar 
S. Nigeria 
Uganda... 
Madeira 
Canada... 
British Guiana... 
Hawaii. .. 
Oribata alula. 
Oribata alata, 0. lucasii, 0. cuspidata, Hoplo- 
derma magnum, Notaspis clavipectinata 
(or a variety of it). 
Oribata alata, Tegeocranus velatus, Scuto- 
vertex sculptus (or a variety of it). 
Hermannia nanus, H. bistriata, Notaspis 
exilis , N. clavipectinata, N. maculosa 1 
and others. 
Oribata alata, 0. quadricornuta, Garabodes 
marginatus, Tegeocranus velatus, Her- 
mannia arrecta. 
Oribata alata, 0. lucasii, 0. cuspidata, 
Tegeocranus velatus, and forms so close 
to the following species as to be at all 
events no more than varieties: 0. globula, 
Liacarus palmicinctus, Hoploderma mag- 
num, Nothrus monodactylus, Garabodes 
labyrinthicus. 
Oribata alata, 0. globula, 0. ovalis, Notaspis 
lucorum and Hoploderma dasypus (or a 
variety of it). 
Several of the consignments of moss contained disappointingly 
little life, being, perhaps, not very well selected. The richest was 
one of the parcels received from British Guiana, and here there were 
certainly many new species. Only very few, however, were at all 
striking, most of them differing from British species chiefly in 
being more highly chitinised and tending to develop excrescences. 
The resemblances, here as in the other cases, were more striking than 
the differences. 
Another point is worth remarking. The most cosmopolitan of 
the Oribatidae are neither the most primitive (to all appearance) 
nor the most active. The genus Oribata is apparently the most 
specialised of the Oribatidae, and seems also to be the most widely 
distributed, 0. alata being the most cosmopolitan of all. Nothrus 
has all the appearance of a primitive genus, as its adults often 
resemble the larvae of Oribata, but we have only obtained one 
British species from the localities in question. Hardly any repre- 
sentatives of the large, long-legged, active mites of the genus 
Damaeus have been received from abroad, and the only known 
jumping Oribatid, Zetorchestes, common on the Continent, has not 
even made its way to England. 
1 First described by Warburton and Pearce from Nine Wells, Cambridge. Since 
then a single specimen was received from Ireland, and now it appears from Madeira.
