She-wolves showed small concern over the clashes of rival males; coyotes never fought with their big gray cousins, and there were no other wolves about. The issue was squarely up to them.

The Osmia who, in tubes of sufficient length, divides her whole laying into a continuous sequence of females and a continuous sequence of males, now breaks it up into short series in which both sexes are present. She adapts her sectional layings to the exigencies of a chance lodging; she always places a female in the sumptuous chamber which the Mason-bee or the Anthophora occupied originally.

A short time previously a female had accompanied one of the males and was at that time somewhere in the vicinity, but beyond this there was no evidence to show that either of them were paired, and even if the presence of the female were the reason of the pugnacity of the one, it could not well account for that of the other.

This is especially clear in the case of those mammals in which the true female uterus bifurcates, for in the males of these the vesicula likewise bifurcates. Leuckart, in Todd's 'Cyclopaedia of Anatomy' 1849-52, vol. iv. p. 1415. The bearing of the three great classes of facts now given is unmistakeable.

The area of their wanderings would be fixed by the existence of other groups; for such groups would almost certainly be mutually hostile to each other, watchfully resenting any intrusion on their own feeding ground. A further, and more powerful, cause of hostility would arise from the sexual antagonism of the males.

The rest of the tribe scampered away over the tops of the trees, crying, "honk, honk, kehonk!" "They are proboscis monkeys, and old males at that; for they have very long noses, which is the reason for the name, and why Achang calls them elephant monkeys," said Louis, as he turned the creatures over. "The noses of these two reach down below the chin.

Tragedy and comedy have tried in vain to frighten or to laugh them out of the indulgence of the fatal passion, that wreaks itself indiscriminately on the beat and the worst, the youngest and the oldest, the simplest and the most guileful of adult males.

Acad. This plant grows on moist rocks; the parts of its flower or its seeds are scarce discernible; whence Linneus has given the name of clandestine marriage to this class. Of the class Confederate Males. The numerous florets, which constitute the disk of the flowers in this class, contain in each five males surrounding one female, which are connected at top, whence the name of the class.

And this leads me to say a few words on what I call Sexual Selection. This depends, not on a struggle for existence, but on a struggle between the males for possession of the females; the result is not death to the unsuccessful competitor, but few or no offspring. Sexual selection is, therefore, less rigorous than natural selection.

The prescribed area included the little village of Dayton, but when a few houses in the immediate neighborhood of the scene of the murder had been burned, Custer was directed to cease his desolating work, but to fetch away all the able-bodied males as prisoners.
