anterior margin. The corpora quadrigemina are large, especially in 

 front. 



The cerebellum is just overlapped at its anterior border by the 

 back of the cerebral hemispheres ; otherwise it is quite posterior. 



The several lemurine resemblances of Tupaia makes the simplicity 

 of its cerebral surface somewhat surprising. 



5. Notes on the Anatomy of Helictis subaurantiaca. By 

 A. H. Garrod, M.A V F.R.S., Prosector to the Society. 



[Keceived March 10, 1879.] 

 (Plate XXIX.) 



A specimen of Helictis subaurantiaca, from China, purchased by 

 the Society on Nov. 26, 1874 \ having died on Nov. 29, 1878, 

 I take the present opportunity of recording some of the most 

 important facts in its visceral anatomy, more on account of the 

 rarity of the animal in this country, than because it presents pecu- 

 liarities of any kind. 



It may first be noticed that the skins of this species collected by 

 Mr. Swinhoe, and now in the national collection, seem to have 

 faded very much in their underparts, which, quite in opposition to 

 that naturalist's original account of his species, are a pure white. 

 It may further be mentioned that Helictis is extremely Badger-like 

 in its proportions, gait, and odour. 



On comparing the skull of the Society's specimen with the small 

 collection of skulls of the genus in the national collection, I found 

 no small difficulty in detecting any intimate resemblance to any. In 

 most of its measurements it agrees exactly with those of H. moschata, 

 as recorded by Dr. Gray 2 . 



In the Society's specimen the skull retained no trace of any 

 sutures, and the lower jaw was considerably diseased, apparently in 

 association with decay of the teeth. I hardly think, however, that 

 extreme old age will account for the peculiarities of the individual 

 under consideration. If differs from other specimens of//, moschata 

 and H. subaurantiaca, and much more resembles H. nipalensis and 

 H. orientalis, in that its zygoma is massive, the prem axillary region 

 short as well as comparatively broad, and the mid-parietal area 

 between the upper margins of the temporal muscular origins de- 

 cidedly broad. The premolar and molar teeth are heavier than in 

 H. moschata and H. subaurantiaca, lighter than in II. nipalensis and 

 H. orientalis, with the two former of which species it most agrees 

 in the size of the zygomatic foramen, with the two latter iu its 

 situation.
