36), from the West Coast of Africa, the male bears on his snout and forehead three curious horns, of which the female has not a trace. These horns consist of an excrescence of bone covered with a etax 2010 download smooth sheath, forming part of etax 2010 download the general integuments of the body, so that they are identical in structure with those of a bull, goat, or other sheath-horned ruminant. Although the three horns differ so etax 2010 download much in appearance from the two great prolongations of etax 2010 download the skull in C. bifurcus, we can hardly doubt that etax 2010 download they serve the same general etax 2010 download purpose in the economy etax 2010 download of these two animals. The first conjecture, which will occur etax 2010 download to every download free game one, is that they are used by the males for fighting together; and as these animals are very quarrelsome (69. Wood also informs me that he once watched two individuals of C. pumilus fighting violently on the branch of a tree; they flung their heads about and tried to bite each other; they then rested for a time and afterwards etax 2010 download continued their battle. With many lizards the sexes differ slightly in colour, the tints and stripes of the males being etax 2010 download brighter and more distinctly defined than in the females. This, for instance, is the case with the above Cophotis and with the Acanthodactylus capensis of S.

In a Cordylus of the latter country, the male is either much redder or greener than the female.

In the Indian microsoft word download Calotes nigrilabris there is a still greater difference; the lips also of the male are black, whilst those of the female are green. In our common little viviparous lizard (Zootoca vivipara) "the under side of the body and base of the tail in the male are bright orange, spotted with black; in the female these parts are pale-greyish-green without spots." (70. Bell, 'History of British Reptiles,' 2nd ed., 1849, p. 40.) We have seen that the males free software.com alone of Sitana possess a throat-pouch; and this is splendidly tinted with blue, black, and red. In the Proctotretus tenuis of Chile the male alone is marked with spots of blue, green, and coppery-red. For Proctotretus, see 'Zoology of the Voyage of the "Beagle"; Reptiles,' by Mr. For the Indian Calotes, see 'Reptiles of British India,' by imgburn download Dr. 143.) In many cases the males retain the same colours throughout the year, but in others they become much brighter during the breeding-season; I may give as an additional instance the Calotes maria, which at this season has a bright red head, the rest of the body being green. Gunther in freeware software downloads 'Proceedings, Zoological etax 2010 download Society,' 1870, p. 778, with a coloured figure.) Both etax 2010 download sexes of many species are beautifully coloured exactly alike; and there is no reason to suppose that such colours are protective.

No doubt with the bright green kinds which live in the midst of vegetation, this colour serves to conceal them; and in N.
