of a Tupaia in spirits, which was received from Borneo, and also a 

 stuffed specimen without a habitat, evidently of the same species. 



These specimens have the general coloration of Tupaia tana, and 

 have evidently been regarded as varieties of that species ; but they 

 are most distinct. The head and skull are short and broad, of about 

 the same form and proportion as those of Tupaia ferruginea ; the 

 fur and tail is of the same bright shining bay as T. tana, but it is 

 entirely destitute of the three black streaks between the shoulders, 

 which are so well marked in that species. 



The skull shows that the stuffed specimen is that of an adult 

 animal not so large as T. tana, and more nearly resembling in size 

 T. ferruginea. It may be known at once from the latter species by 

 the dark red-brown colour of the tail, with its very red underside. 

 I propose to call it 



Tupaia splendidula. 



Fur dark red-brown, blackish-washed. Tail dark red-brown ; 

 pale red beneath ; the shoulder-streak yellow. The head conical, 

 about twice as long as wide behind. 



Hah. Borneo. 



The head is large compared with the size of the body ; the ears 

 rounded, with several ridges on the conch, and a well-developed con- 

 vex tragus, not unhke the human ear. The palm and soles are bald 

 to the wrist and heel. 



I thought at first that this species might be the Tupaia speciosa of 

 Wagner ; but that animal is stated to have a head as long and as 

 tapering as T. tana, and, indeed, seems to be only a slight variety of 

 that species. 



Notice of a New Genus and Species of the Family Trio- 

 NYCHiD^ from Western Africa. By Dr. J, E. Gray, 

 F.R.S., F.L.S., etc. 



The British Museum has just received two specimens of a Trionyx 

 with covered legs from Western Africa (collected by the late Dr. B. 

 Baikie, probably on the Niger), which is evidently different in 

 structure from any we have before received from that country, and 

 which I am inclined to believe is an entirely new form. 



It differs from the other African Trionyches with covered feet in 

 only having two pairs of callosities on the sternum ; while Hepta- 

 thyra has seven, and Cyclanosteus has nine such hardnesses on the 

 sternal bones. These callosities differ in disposition and mode of 

 development, as well as in manner, in the three genera. The skull 

 is in form like that of the genus Cyclanosteus; that is to say, 

 the face is moderate, with eyes about halfway between the front of 

 the zygomatic arch and cavity of the temporal muscle and the end 

 of the nose ; but it differs from the skull of the latter genus in the 

 forehead and crown being wider and flatter. 



The genus (which I should refer to the tribe Cyclanosteina) may 

 be defined thus : —
