DurinG the recent examination of some old algal material from 
Penyghent, W. Yorkshire, I came across a dilapidated specimen 
of a Tardigrade, the like of which I had no recollection of having 
seen before. Further search through the material fortunately 
resulted in the finding of several individuals in a much better 
state of preservation. 
The animal appears to be a variety of Afacrobiotus papillifer 
MAGCROBICTUS PAPILLIFER }-Manray , VAR. 
A.—Animal seen from the side, x 500. 
B.—Single dorsal process showing the two minute apical spines, x 1000. 
C.—Pair of claws, x 1000. 
James Murray (‘The Tardigrada of the Scottish Lochs,’ Zvazs. 
Royal Soctety, Edinburgh, vol. xli., part ili., No. 27, 1905, 
p- 692, t. iii., f. 15 a-c). The specific name ‘ papillifer’ is in 
reference to the conical papillae or processes along the dorsal 
surface and sides of the body. These projections are disposed 
in transverse and longitudinal rows, each one having an acu- 
minate apex. 
The Yorkshire animals were collected in April, 1896, and 
occurred among mosses, and the submerged portions of sedges 
and rushes in a small rivulet on the western slope of Penyghent
