Rapid colour change in mirror spiders, sequined spiders and similar ‘white’ spiders derives from crystalline guanine in guanocytes.

In 1837 a small fossilized beetle was discovered in Carboniferous deposits of England, and its description was promptly published in "The Bridgewater treatises on the power, wisdom and goodness of God as manifested in the creation." Unfortunately, two things were wrong with this publication. As it turned out, the creature was not a beetle, but…

Warning! If you are arachnophobic you may not want to see this list, but I really suggest that you do. You may find that these creatures are more diverse and fascinating than they are creepy. Spiders have never ceased to amaze me; they are among the most abundant predators in the world and have adapted to almost any imaginable habitat except for the sea, giving rise to countless species many of which remain unknown to science. If people would stop to watch spiders instead of simply squashing them on sight, I'm sure they would be amazed constantly. This list is only a very small selection of bizarre spiders from around the world.

The web of Epeira diadema is one of the most beautifuland most common of the spider constructions in this country,being found in every bush or tree, between hedges andshrubs, &c., during the autumnal months. The top line ofthis web appears to be first spun, either by attaching a threadas above described, and then carrying it along until it is ofsufficient length, when it is attached to some adjacent objectto which the spider has crawled, or by tlirowing out a float-ing line, whilst the spider remains stationary, the action ofthe air carrying this line on until it becomes attached tosome object, when, in either case, it is doubled and re- 136 ARACHNIDA. doubled until it is of sufficient strength to bear the weightof the intended fabric, together wath the spider itself.

Mr. Blackwall has noticed the curious fact that thosespecies of spiders which form geometric nests, are furnishedwith several claws on each foot, whilst some of the jumpingspiders, and some others, have only two claws. In severalspecies of Epeira it will be distinctly perceived that the in-ferior part of their feet is provided \^ith several claws, whichhave a degree of curvature, are finely pointed, and are fur-nished with tooth-like processes in the under side. In Epeiraapoclisa there are as many as five of these claws, which, inad Note About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.
