The intermediate stage of the grub. The outer skin 
hardens into a tough envelope, and the breathing- 
tube, which is no longer wanted, becomes contracted. 
As this stage progresses two horns appear. These 
are breathing organs. 
from above by a leaf-like scale, such as may be seen on 
the big, many-hued worm that occupies the centre of the 
coloured plate. This magnificent worm is a representa- 
tive of the Leaf-worms, which are so-called because of 
these organs, of which they have one on each side of 
every ring of their long, centipede-like bodies. Some of 
them also have gills upon these lateral protuberances. 
So various are the Sea-worms that, whilst some 
have heads ornamented with few, or many, antenne, 
two or four eyes, jaws of varying number; others 
have no head, or a head minus antenne, or jaws, 
or eyes. They swim in the sea, twine round sea- 
weeds, explore empty shells, or live in crevices of 
the rocks—some even bore holes in the rock for a 
habitation. One of those that live in crevices is 
shown to the left of the coloured plate. He belongs 
to the more worm-like section, which includes the fisher- 
man’s “Lug.” Its feet are branched, and from the 
upper branch he can protrude a long thread which ap- 
pears to be of the nature of a feeler. These threads 
are especially abundant near the head, and they are 
drawn out to an enormous length, proportionately to 
the size of the worm. At night they are luminous, and 
we have often surprised our friends by gently prodding 
the worm and so stimulating it to glow through all these hair-like threads with a phos- 
phorescent light. 
One other diverse form must be mentioned—the black Long-worm shown on page 958. He 
looks like an enormous boot-lace that by long soaking in the sea has become very soft and flabby, 
and has got into a hopeless tangle. 
One hesitates to mention its length. Many have tried to 
unravel the tangle, but when a few feet have been carefully straightened out this part begins

usually given up for lack of time, and perhaps of 
patience. Professor Mackintosh essayed to unravel 
one that ‘“‘half filled a dissecting jar eight inches 
wide and five inches deep. Thirty yards were measured 
without rupture, and yet the mass was not half un- 
coiled.”

THosE who wander through the galleries of fossil 
animals at, say, the British Museum must often be 
tempted to ask: “Can these dry bones live?”’ And 
every now and again the artist, seeking new themes, 
will make an attempt at the difficult task of resuscita- 
tion. In the accompanying plate the accomplished 
animal painter, Mr. C. Whymper, has conjured up for 
us a scene such as may well have taken place a few
