rather more numerous (from further subdivision), some of them only faintly indicated, 
the lumbar with its anterior portion not forming separate plates—general arrangement 
the same; dots very minute, as in H. arctomys. (Plate I. fig. 2b.) 
These two varieties can be distinguished among the smallest individuals, and appear 
to be constant, no intermediate states having been found. The differences are not 
sexual, both having been repeatedly found with eggs. A spine on the first leg, and 
palp on the fourth, have been frequently seen in both varieties. 7 | 
Reproduction.—Kgegs from one to four in number, laid in the moulted skin. An 
example measuring z+, inch (about 116) laid a single narrow egg, which measured _ 
sty inch by 54, inch (43 by 26u). Larger examples laid two, still larger three, and 
the largest observed four eggs, which are larger and relatively broader, those in one 
skin measuring 34, inch by ;4, inch (66 by 504). They are usually dull yellow, but 
sometimes pale red. It appears from the above measurements that the species lays 
eggs when far from full grown. The newly-hatched larva has not been seen, but young 
measuring no more than 33, inch (110) had four claws, the inner barbed, and all 
other outward features of the adult. 
Related to EZ. arctomys, which it resembles in narrow form, obscure plates, slender — 
legs, lack of fringe, and in the finely punctate skin, it differs in the larger size, more 
numerous plates, and in having barbs on all the inner claws. Size, up to ~, inch, 
exclusive of legs ( = 269). 
In Loch Ness, Loch Morar, and ponds at Fort Augustus, abundant—1903-—4. 
Echiniscus wendti—Ricuters. (Plate I. figs. 3a to 3c.) (10), (15). 
Specific Characters.—No setee except the usual six on the head, the lateral sete 
at the back of the head twice as long as in H. arctomys. A fringe on the last legs. 
A strong decurved barb on inner claws of last legs. Granulation small and uniform. — 
A spine on the first leg, and a blunt palp at the base of the fourth. 
Arrangement of Plates.—(1) Head; (2) Shoulder; (3) Median triangular; (4) — 
Pair; (5) Median triangular; (6) Pair; (7) lacking; (8) Lumbar, trefoliate. 
Its discoverer distinguishes the species by the long head seta, the fringe, and the 
strong barb. Examples from Loch Morar agree in all those characters, but the 
granulation is rather coarse, and appears to be variable. 
Loch Morar, 1904, frequent. 
Echiniscus reticulatus, n. sp. (Plate I. figs. 4a to 4c.) 
Specific Characters.—Stout, broad, bright red. Plates ten, arranged on the 
normal plan. Lateral setze on head very long. Plates covered with pattern of large 
hexagons or circles, a slightly raised rim enclosing a flattish depressed surface. A long —
