220 British Oribatidce : Notes on New and Critical Species. 
and bounded on either side by a long narrow very acute 
process of the pteromorpha, half the length of the cephalo- 
thorax. This process tapers evenly to the extremity, and 
is not deflected ; the front margin of the pteromorphae 
beyond it is on a level with the median point of the pro- 
dorsum. Dorsal hairs none. 
Lamellae pale brown, triangular, very long and narrow, 
horizontal, inner margins contiguous except at the very 
extremity where they are slightly divergent ; outer margins 
also quite straight with a thickened rim. A serrate seta 
projects from beneath the extremity ; the pair of setae are 
thus close together, projecting half their visible length 
beyond the rostrum. Rostral hairs incurved, running 
parallel to the sides of the rostrum. Interlamellar setae none. 
In moss and under stones in grassy places. West Allendale 
and Cullercoats. 
O. redux sp. n. (Plate A, fig. i). 
Length about 520 p.. 
Dorsum black brown ; quite smooth but not very glossy, 
with a clearly outlined yellow spot in front ; outline oval, 
dorsal hairs none. Pteromorphae extending beyond the 
middle of the dorsum. The prodorsal margin is evenly 
curved, not running forward to a point as in ovalis and 
hasticeps ; the front margin of the pteromorphae (the lobe 
excluded) is on a level with it. Lobe of the pteromorpha 
not deflected, its extremity obliquely truncate. 
Lamellae yellowish, broad, horizontal, enclosing an 
equilateral space, fore margins concave, forming with the 
doubly curved lateral margins acute inward-pointing cusps. 
I should have taken this to be the ovalis of Nicolet ( non 
Koch!), only in that species the lamellae are said to be 
inclined at an angle of 45 degrees, and the fore margin of the 
dorsum is figured of the same form as that of ovalis Koch. 
It has occurred at Wooler ; Ninebanks, West Allendale ; 
and elsewhere in Northumberland, but never very freely.

6d. net. The object of this little volume of ‘ The People’s Books ’ series 
is to enable beginners to identify some of the commoner wild flowers likely 
to be met with in a country walk. A brief introduction gives an ex- 
planation of the more useful descriptive terms, and is followed by ten 
chapters dealing with 200 species which are grouped according to the 
colours of the flowers — white, yellow, red, purple, blue, brown, green, etc., 
and each group is further sub-divided according to leaf shape, inflorescence 
and flower characters. The descriptions of the species are very simply 
worded and identification is further aided by an illustration of each species. 
The figures are evidently from the well-known ‘ Illustrations of the 
British Flora,’ by Fitch and Smith.
