. The Australian zoologist. Zoology; Zoology; Zoology. BOARDMAN. 153 tinge to the general surface of the body. In G the hair is well developed except in the lower part of the back approximately corresponding with the limits of the pelvis. Hair Tracts.âThe terminal member of the series, G (175 mm., $), is in the best condition for examining the disposition of the hair tracts. As in the related Vombatus ursinus tasmaniensis described by Wood Jones (20) the primitive arrangement of the hairâcaudalwards and ventrally on the head and trunk, postaxially on the limbsâis in evidence, but not so completely as in that form. In the specimen before me varia- tions from this arrangement occur on the head and neck. There is no reversal on the muzzle immediately behind the rhinarium, but the hairs are readily separable from those adjacent by their more bristly character, their darker pigmentation, and the fact that they do not lie flat against the skin but are distinctly elevated from it. From this restricted some- what specialized zone two currents take origin, each flowing towards the anterior can thus of the eye on their respective sides; no divergent parting is in evidence except on the caudal margin of the main area; some hairs from the left side flow towards the right so that the stream on the left side is noticeably smaller at its origin than that on the right (Fig. 9). The even backward flow of hair on the top of the head is interrupted im- mediately in front of the line joining the anteriormost portions of the attachment of the auricles by the interposition of a divergent parting about 1 cm. in length from which hair flows towards the base of the ears; this parting is not quite symmetrically placed but lies obliquely with reference to the middorsal line (Fig. 9). tf.*>Y m^ &h «> â M >s\ \W. â M ^ Fig. 9.
