Original text on this topic:
R.lasiotis. In the first place, with regard to the external characters of colour and hair development, a comparison of the head-skin of R. lasiotis with the two specimens in the Museum of 'Ceratorhinus niger' leads me to the conclusion that the differences described were mainly due to age. For it will be remembered that the 'C. niger' (that is to say the specimen determined by Sclater as sumatrensis and used by him for his comparison with lasiotis) was very old, while the type of lasiotis was then quite young. In its old age, the latter has become practically quite like the former, for the tufts on the ears do not exceed l ? -2 inches in length, and are in no way noticeably different from those of the Malaccan specimen. In fact, Dr. Anderson's supposition (P.Z.S. 1872, p. 130) that the tufts on the ears might wear off with age, seems to me entirely confirmed by the evidence, so far as can be judged from a menagerie specimen.
