pressed yellowish white hairs beneath, and with reddish brown 

 woolly fur on the upper surface, terminated by a tuft of dirty yel- 

 lowish brown; ears elliptical; head small and attenuated; tarsus 

 long, and of a pale greyish white colour ; middle upper incisors not 

 so much longer in the lateral as in Hyp. murinus, and lower shorter 

 and slenderer ; the canines are nearly in contact with the lateral in- 

 cisors, and of the same form and size. This is the species described 

 in Governor Phillipp s Voyage ; that figured by White appears to 

 be Hyp. myosunis. Described from two specimens in the Linnean 

 Society's Collection. 



6. Hyp^Cuniculus : in size and colour something resembling Hyp. 

 Phillippi, but of a clearer grizzled brown colour, something Uke that 

 of the wild rabbit ; a dark brown patch marks the nose ; tail long, 

 cylindrical, and terminated by a tuft of coffee-coloured wool ; upper 

 middle incisors very large, separated from one another and truncated ; 

 the lower of the same form, but considerably shorter than in any 

 other species, and the canines much smaller than the contiguous 

 lateral incisors, and separated from them by a distinct bar or vacant 

 space ; by aU which characters this animal differs from Hyp. Phillippi, 

 as well as by its larger and thicker head and clearer grey colour. 



7. Hyp. murinus : of nearly the same colours as the last two spe- 

 cies, but readily distinguished by its short, thick head, blunt, unat- 

 tenuated muzzle, and very short ears bordered with red : the teeth 

 also afford a very distinctive character ; the lower incisors are twice 

 as long as in the last species, the upper not much longer than the 

 lateral, and the canine only half the size of the contiguous incisor, 

 and nearly in contact with it, being separated only by the third part 

 of a line ; the tail is furnished with an erect crest of black hair for 

 three or four inches towards the tip : this is the " Potoroo" of the 

 French Zoologists, as Mr. Ogilby had verified by comparison with 

 the Paris specimens. Mr. Ogilby remarked that by an oversight 

 for which he was accountable, the Society's specimen of this animal 

 is called Hyp. setosus in the recently published Catalogue of the 

 Mammalogical part of the Collection. 



Mr. Martin then brought before the notice of the Meeting three 

 species of Chameleon from Fernando Po, forming part of Mr. Knapp's 

 donation, and upon which he proceeded to offer the following obser- 

 vations. 



" Among the collection of specimens from Fernando Po lately pre- 

 sented to the Zoological Society are three chameleons of peculiar 

 interest. One of them is the Cham, tricornis, or Oweni of Mr. Gray ; 

 the second is the Cham, cristatus of Mr. Stutchbury, described and 

 figured in the 3rd Part of the 17th Vol. of the Linn. Trans. The 

 third appears to me to be undescribed. 



" M^'ith regard to the specimen of Cham, cristatus, I may be per- 

 mitted to point out some trifling differences between it and the 

 figure given by Mr. Stutchbury, The crest ceases to be elevated 

 over the loins and base of the tail, degenerating into an acute ridge, 

 whereas in the figure it continues for a considerable distance along
