THE TARDIGRADA OF THE SCOTTISH LOCHS. 685 
sharp spine on front legs, a blunter spine on the last legs. Fringe on last legs. All 
inner claws with very small decurved barb near base. 
Resembling #. wendti in having very long lateral setee on the head and no other 
setze on the body, it differs in the texture of the plates, the small barbs of the inner 
claws, and the presence of the third median plate. This plate is variable, and sometimes 
appears to be united to the lumbar plate, though at other times quite distinct. The 
hexagonal pattern on this plate is very faint or quite obsolete. The lumbar plate is 
rendered trefoliate by two deep cuts, and is besides divided into four facets, the two 
lateral and the posterior facets being bent at a sharp angle to the median facet. This 
gives the appearance of a separate anal plate; but there is no real separation, the 
pattern passing uninterrupted over the angle. The length of the lateral seta is equal 
to the diameter of the body at the shoulder, or much greater. The teeth of the fringe 
are often bifid. 
feproduction.—One to four eggs laid in the cast skin, the larger number laid by 
larger, and presumably older, individuals. A skin measuring ;+, inch (214) contained 
three bright red eggs of 54, inch by ghy inch (71 by 59). The head seta in this 
measured ;4+, inch (142u). The newly-hatched larvee have not been seen, but in- 
dividuals so small that it might be supposed they had not moulted since hatching had 
four claws, with the inner barbed, and the reticulated plates quite distinct. 
Loch Morar, very abundant, Loch Ness, rare—1903—4. It has not yet been found 
anywhere except in lakes. 
Echiniscus ochonna—Ricuters. (Plate I. figs. 5a-5b.) (10), (15). 
Specific Characters.—Small, plates ten, only two median triangular, anal plate 
separate. Five lateral sete or spines, and two dorsal spines, on each side. Fringe on 
last legs. Barbs on the inner claws, those of the last claws very strong. 
Arrangement of Plates.—(1) Head, with longish lateral seta; (2) Shoulder, long 
lateral spine and smaller one above it; (3) Median, triangular; (4) Pair, lateral seta and 
small spine, strong dorsal seta; (5) Median, triangular; (6) Pair, lateral curved spine 
and short spine, dorsal short spine ; (7) lacking ; (8) Lumbar, very long whip-like seta ; 
(9) Anal. In Scottish examples the anal plate is not separate. 
Only two examples seen; no eges. Margin of Loch Ness, February 1904. Loch 
Karn. 
Echiniscus granulatus—Doy. (Plate II. figs. 6a to 6f-) (3), (5). 
Specific Characters.—Plates nine, arranged in the normal manner, coarsely granulate. 
Three long lateral sete, and a short spine at the junction of the tail-piece with the 
lumbar plate ; two dorsal setze or spines on each side. Spine on front leg, and blunt 
palp on last leg. Fringe on last leg. Inner claws with decurved barbs. 
Arrangement of Plates.—(1) Head, with moderate lateral setze; (2) Shoulder ;
