=Note A, p. 14.=--Atypus piceus is a European species of Tunnelweaver (Territelariæ), which inhabits Great Britain. It resembles in habit our Atypus Abbotii, the Purse-web spider, found in the Gulf States, especially Florida; but supports its external tube upon the trunks of trees, instead of on the grass or surface. =Note B, p. 16.=--Spiders are extremely cleanly in their habits, and brush and comb the various parts of the body with their hairy and spinous legs and palps. When brushing the head and chest (cephalothorax) the resemblance to the cat's toilet habits warrants the reference in the text. =Note C, p. 18.=--Some of our American spider species have been imported from Europe, and I have seen them on vessels stowed away in divers crannies and under sundry parts of the ship, and overspun in the method attributed to Spite and his companions, and shown Fig. 15. CHAPTER III. =Note A, p. 22.=--Epeïra globosa is a species of Orbweaver, which spins above its round snare a bell-shaped silken tent, represented at Fig. 17, p. 21. =Note B, p. 22.=--One of the most common webs spun upon grass, on box-wood borders of flower beds, on arbor vitæ hedges, and such like positions, is that of the Speckled Tubeweaver, Agalena nævia, here described. It is a broad sheet, usually concave or funnel-shaped, with a circular opening near the middle or at one side, which leads into a long silken tube extending downward among the branches, or to the ground. At the opening the spider is usually seen waiting for prey. Lines are attached to the sheet at various parts and reach upwards to bits of foliage, forming a network of lines which support the sheet. Insects in flight strike against these cross lines, and fall down upon the sheet, and become the prey of the Speckled Agalena who rushes upon them from the opening of her tube. =Note C, p. 24.=--The cables here referred to are the upright lines described in Note B. (See Fig. 28, p. 54.) =Note D, p. 26.=--The turret of Lycosa arenicola, is here described. It is popularly known as the Turret Spider. This animal is widely distributed throughout the United States, and may be found along the Atlantic shore where it burrows in the sand, and sometimes selects small pebbles for the foundation of its tower. The shape of the tower is not always a regular pentagon, but inclines to take that form. Beneath the surface is a tubular burrow extending straight down as far sometimes as twelve inches. The spider is frequently found on guard at the top of the tower. =Note E, p. 26.=--See Note A above. The web of the Speckled Agalena when spun upon grass often takes this form and shows a striking likeness to a miniature circus tent. =Note F, p. 27.=--The Turret Spider is sometimes seen at the summit of its tower with head and fore limbs thrust over the edge, apparently on the lookout for passing insects.
