 precisely what a gill-slit is in other animals. 



A final matter of interest in connection with the tonsils 

 of the Sperm- Whale is the variable occurrence of these 

 organs among the Cetacea. Shulte *, in a fostus of a 

 Korqual, "" found no truce of a tonsil." This is, however, 

 not a question of whalebone-whales differing from the 

 Odontocetes, for Macalister f also '^ found no trace of a 

 tonsil •'^ in Gbbicephalus melas, while Mnrie J, in his elaborate 

 account of the same whale, does not mention that organ.

Thanks again to the generosity of Col. Stephenson Clarke, 

 C.B., the British Museum has received as a donation a further 

 series of mammals from the highlands of Yunnan, additional 

 to those described by Mr. Hinton and myself in previoug 

 numbers of the^ Annals.' The present series, which numbers 

 about 300 specimens, were all obtained in the Li-kiang 

 Eange (27° N., 100° 30' E.), and on this account I have 

 repeated here the names of the only species from that range 

 obtained in the first collection but not in the second; so that 

 the present paper forms a complete list of all the mammals 

 as yet known to occur there. 



Naturally the great majority of the species now received 

 ■were included in the first collection, but, none the less, this 

 supplementary collection is a most valuable addition to the 

 Museum, especially as the specimens were for the most part 

 collected at a different time of the year, so that seasonal 

 changes, previously unknown to us, are now generally 

 represented. 



Some new forms do occur, however, notably a flying' 

 squirrel of the rare genus Trogopterus, the new species bein
