I have frequently found males lacking several legs. The theory commonly adopted is that in most of these cases the loss has ou ing rcsujtet| fvom conflictSj perhaps among rival lovers in attendance upon the same female. Something of loss may be attributed to this cause, but I am satisfied that in a much larger degree losses and mal- formations are due to the accidents of moulting. One example I may cite, the loss of two limbs experienced by a large tarantula which I had kept under observation. This spider lay upon its back in the araneary during part of the time of moulting, and on its side during the remainder thereof. The skin was cast by a succession of movements of the body or parts of the body recurring at reg- Limbs ujar intervals, reminding one of labor pains among mammals. M ,,. For some reason two of the legs refused to separate from the skin, and after a prolonged struggle they were broken off at the coxte, and remained within the moult. (See Fig. 64.) One foot of another leg shared the same fate. This moult oc- curred in the spring; during the latter part of August of the same year the spider again moulted. The moult was a perfect cast of the animal, the skin, spines, claws, and the most delicate hairs showing, and their cor- responding originals appeared bright and clean upon the spider. When the castoff skin was removed the dissevered members were lacking thereon, but on the spider itself new limbs had appeared, perfect in shape but smaller than the corresponding ones on the opposite side of the body. The dissevered foot was also restored. The rudimentary legs had evide
