Show 1891.] MR. F. E. BEDDARD ON HAPALEMUR GRISEUS. -149 usually head downwards, but in whatever position they may be the head and fore part of the body is raised. They scramble about very quickly, but like all lizards soon exhaust themselves and can then be easily taken. They permit persons to approach near to them when first discovered, but soon become alarmed. When on trees, like squirrels and woodpeckers, they have a habit of placing themselves on the opposite side to the one in view. They live on spiders, beetles, and caterpillars, and in captivity eat cockroaches with avidity, managing sometimes to swallow very large ones. In confinement they have laid cylindrical-shaped eggs an inch long, covered with tough, white, slightly ribbed, parchment-like skin. 7. Additional Notes upon Hapalemur griseus. By FRANK E. B E D D A R D , M.A., Prosector to the Society. [Received June 15, 1891.] In the 'Proceedings' of this Society for 1884 (p. 391 et seqq.) I published a few notes upon the external characters and visceral anatomy of Hapalemur griseus. Since that date I have had the opportunity of dissecting two other examples of this Lemur, and am able to supplement my former paper with some account of the brain and the muscular system. Unfortunately both these individuals were, like the one which I first dissected, males. It is very desirable that the condition of the patch of modified integument upon the arms, so characteristic a feature of this animal, should be figured in the female. It was first figured for the male Hapalemur griseus by myself, and subsequently by Mr. Bland Sutton1; but although Mr. Sutton's figure supplemented my own in directing attention to a tuft of long hairs, overlooked by myself, in the neighbourhood of the patch of spines, we both of us omitted to observe one detail which will be noticed in the accompanying drawing (fig. 1, p. 450). In the specimen before me the patch of spines is very well and equally developed upon both arms; it extends down as far as the naked skin of the palm of the hand, being thus more extensive than in the former examples figured by myself and by Mr. Sutton; towards the middle of the patch the spines were distinctly longer than elsewhere; to the outside of the patch, on both arms there was a smallish oval tract of thick skin like one of the pads on the palm of the hand, with lines running transversely to its long axis. Both I myself and Mr. Sutton had failed to notice this callous pad. On re-examining the skin of the individual which I first dissected, I have found indications of this pad, which is, however, not at all clear in the dried skin. I fancy that it must also have been inconspicuous before the skin was removed; it is so plain in the specimen before me, that 1 cannot understand having 1 "On the Arm-gland of Lemurs," P. Z.
