Show 1901.] MR. F. E. BEDDARD ON GALAGO GARNETTI. 273 characteristic of the species, at least of the males of that species. It is quite likely therefore that these horny spinelets are equally characteristic of Galago garnetti, though unfortunately through an oversight I a m not able to say anything about the sex of the individual examined by myself. Mr. Sutton held that in Hapalemur " the patch of spines was in reality formed by the hardened secretion of the gland underlying them." In this case the structure could have no possible relation to hair or spines, or to any m a m malian integumental callosities ; they would be rather comparable to the cuticular " hairs " and spines of Arthropods. One argument against Mr. Sutton's view appears to m e to be this : the lumen of sebaceous and other integumental glands-indeed of all glandular structures-is either circular or oval; in any case without angles. N o w the spinelets of this Galago, as may be readily noted in the more highly magnified drawing (text-fig. 72) which I exhibit, are distinctly quadrangular; and the same angular character was noticeable in the arm-spines of Hapalemur. Text-fig. 72. Galago garnetti. Patch of horny outgrowths, more highly magnified. A, the main patch ; A', a group of smaller outgrowths. It is difficult to imagine that the squeezed-out secretion of a tubular glaud would have an angular contour. The existence of a large gland in Hapalemur lying beneath (though as far as I can recollect not exactly corresponding to) the patch of spines lends of course some colour to the view of the glandular origin of the structure in question in that Lemur. After removal of the skin iu Galago garnetti, no gland was to be observed beueath the patch of spines. 1 do not propose to assert the total absence of integumental glands in this region : but no large glandular body comparable to that of Hapalemur griseus was visible.
