is brought into more light. A slumbering, glowing, inward light, as if shining for itself inward as much as outward. The other worm, which was at first curled up still and emitted a duller light, was one and one twentieth inches in length and also showed two dots of light only on the forward segment. When stretched out, as you look down on them, they have a square-edged look, like a row of buns joined together. Such is the ocular illusion. But whether stretched out or curled up, they look like some kind of rare and precious gem, so regularly marked, far more beautiful than a uniform mass of light would be.
Examining by day, I found the smallest to be seven eighths to one inch long, and the body about one sixth of an inch wide and from one thirteenth to one twelfth of an inch deep, convex above, pointed at head, broader at tail; head about one twentieth of an inch wide. Yet these worms were more nearly linear, or of a uniform breadth (being perhaps broadest at forward extremity), than the Lampyre represented in my French book, which is much the broadest behind and has also two rows of dots down the back. They have six light-brown legs within a quarter of an inch of the forward extremity. The worm is composed of twelve segments or overlapping scales, like the abdominal plates of a snake, and has a slight elastic projection (?) beneath at tail. It has also six short antennæ-like projections from the head, the two outer on each side the longest, the two inner very short. The general color above was a pale brownish yellow or buff; the head small and dark-brown; the antennæ chestnut and white; white or
