524 THE PILL-MILLEPEDE. 
The color of this centipede is yellow; its head is deep rust color; its antennz are very 
hairy and four times as long as the head segment. There are from fifty-one to fifty-five pairs 
of legs. Its length varies from two and a half inches to three inches. 
Our next example, the Gonibregmatus cwmingii, is remarkable for the enormous number 
of rings of which the creature is composed, and the consequent number of legs which are 
needed to carry it over the ground. Although this species is only from four to five inches, it 
has no less than three hundred and twenty-two legs. It is a native of the Philippine Islands, 
whence so many wonderful forms are brought. 
The rather harsh generic name of this creature is composed of two Greek words, the 
former signifying an angle, and the latter the top of the head, and is given to the animal 
because the front edge of the head is formed into an acute angle. The general color of the 
species is ashen-gray, and the mandibles are black at their tips. 

CHILOGNAT A. 
We now come to a new group of Myriapoda, where the creatures have the power of rolling 
themselves up, more or less completely, like the hedgehog and the pill-woodlouse. A new 
species of this group has been termed Zephronia impressus. It is a native of Borneo, and 
was found by Mr. A. R. Wallace. The general color of the creature is rusty-brown, inclining 
to red; the head is edged with blackish-brown, and the front segment is also edged with the 
same color. ‘The surface is shining and polished, and all the segments, except that at the end 
of the body, are marked with deep longitudinal impressions. For this reason, I call the 
species ‘‘impressus.’? Its length is nearly two inches. 
Before leaving these creatures, it may be as well to state that, during the earlier stages of 
their existence, these animals are much less perfect than when they have reached adult age ; 
they have not their full complement of segments or limbs, nor an equal number of eyes. The 
metamorphosis, therefore, is complete, and serves to show the relationship between the Myria- 
poda and the insects. 
Some species of this genus are remarkable for their beautiful markings, and the aspect 
which they present when rolled up for defence. 
One of them, the Actzeon Millepede, is a native of Madagascar, and was noted by the 
celebrated female traveller, Madame Ida Pfeiffer. The surface of its body is very polished 
and shining, and the general color is a livid yellow. A number of tiny puncturations are 
scattered rather sparely at the back of the head and between the eyes, but in the front they 
are more numerous, and along the sides they are nearly as thick as the little depressions on 
the end of a thimble. The species may also be Known by the shape of the eighth to the 
eleventh segments included, which are curiously pointed, looking as if they had been snipped 
off diagonally with scissors. 
The body of another species, termed Zephronia versicolor, is very smooth and beautifully 
colored, being of a yellowish ground tint, boldly variegated with stripes and spots of deep 
black, so as to render it extremely conspicuous. The front of the head, the eyes, legs, and 
antennze are pale green in the preserved specimens, and are thought to be darker during life. 
The head is marked with distinct points. This beautiful species is further remarkable from 
the fact that no two specimens ever seem to be colored exactly alike. On the upper ridge of 
the face there are from eight to ten little short spines. This species is a native of Ceylon. 
These creatures are all natives of the hotter parts of the earth, but there exists an allied 
example in almost every garden, and certainly in every field throughout the greater part 
of Europe. This is the PILL-MILLEPEDE (Glomeris margindta). It is found among moss and 
under stones, and, as if rolls itself up in a manner very similar to that which is employed by 
the armadillo-woodlouse, is often mistaken for that being. It may, however, be readily dis- 
tinguished from that crustacean by the simple fact that the legs have their origin on a single
