D., VETERINARIAN, Moravia, N. Y. In the July number of the last volume I described how the young tick hatching from the so-called egg, passed through a sixlegged and an asexual eight-legged stage to again moult before emerging as adult ticks. The differences between the ticks destined to become either male or female during their final moult is not marked. The average of the males is smaller, but a small female may not be any larger than an ordinary male. In each the mouth ring and mouth parts, the shield-like head-piece, the breathing pores, the limbs and the body are alike. After they emerge, however, the males can be quickly chosen by their smaller size, by the absence of a well-defined head shield, by the extension of the shield over entire back, and by the two pairs of triangular chitinous plates, situated on the abdomen, behind and on each side of the anus. The female looks much as in her earlier stage; the head shield is, however, larger and stronger, the lines made by the muscular attachments to the body-walls are stronger and deeper, and the breathing pores are much enlarged. The limbs, in both male and female, are strong and large as com-. pared with their bodies, and fit them for retaining their place on their host until th have gained a new attachment by their mouth or rostrum. The external genitals which appear in the adults are very similar in each sex, and occur between the bases of the second pair of legs. They present little more than an opening situated on the middle line of the belly. Throughout life the male enlarges but little ; he becomes a little broader, longer and thicker, but not markedly so.
