Hab. North coast of Australia. 



This species is of the same size, but more elegantly formed than 

 the Lob. lobatus, the fleshy wattles more extensively developed, the 

 crown of the head only black, and not the back and sides of the 

 neck, as in that species. 



Mr. Waterhouse exhibited several species of Mammals, collected 

 in Borneo by the Society's Corresponding Member, James Brooke, 

 Esq., and recently forwarded to England by that gentleman. 



Among these specimens Avas a fine example of the Puradoxurus 

 Derbianus, Gray, an animal which has also received the names 

 Paradoxurus Zebra, Hemigalea Zebra, and Viverra Boiei. 



Two specimens of Gymnitra, a specimen of the Prionodon gracilis, 

 and two species of Squirrel, also formed part of the collection. 



The Gymnuri differ much in colouring from the G. Kafflesii. In- 

 stead of having the fur black, and with longer interspersed white 

 hairs, the Bornean specimens are entirely of a yellowish white colour, 

 with the exception of the long bristly hairs interspersed with the 

 ordinary fur, which are some of them black. In other respects the 

 Sumatrau and Bornean specimens of Gymnura agree so closely that 

 Mr. Waterhouse did not regard the difference in colouring as indi- 

 cative of specific cUstinction. 



The existence of the Prionodon gracilis in Borneo is noticed by 

 Miiller, M'ho applies to the animal the name Linsang gracilis. Be- 

 lieving the skull of this animal had never been described or figured, 

 Mr. Waterhouse called attention to the peculiarities in its structure. 



In some of its external characters, especially in the structure of 

 its feet, with their truly retractile claws, the Prionodon evinces an 

 affinity to the Cats, which would lead the naturalist to seek for some 

 corresponding points of resemblance in the skull; this, however, 

 presents all the characteristics of the Viverridce : it is of the same 

 elongated form ; the lower jaw is long and slender, and the rami are 

 curved, so that the angular portion and symphysis are raised. Com- 

 pared with other Viverrida, the Prionodon skull is remarkable for 

 the thinness of the bones and the very slight development of the 

 muscular ridges. In general form it approximates more nearly to 

 Paradoxurus than to Viverra or Genetta. The zygomatic arch, which 

 is slender, is thrown more boldly outwards than in the last two 

 mentioned genera, and the posterior portion of the cranium does not
