270 Mr. W. L. Distant 07i Sphingidge 



26*5; palatal forarnen, length 7"9; back of incisors to molars 

 13"6 ; length of molar series 9*4. 



The typical specimen, as well as the two new squirrels 

 described in the August number of the ' Annals,' was obtained 

 at an altitude of more than 3000 feet, Mr. Whitehead not 

 commencing to collect until he had passed this height. 



Mus sabanus may be readily distinguished from any of the 

 species above mentioned by its enormously long tail, the 

 peculiar coloration of its hands and feet, and by its size, M. 

 Edwardsi alone being very materially larger, and all the 

 others considerably smaller. 



One species, however, also a native of Borneo, has a super- 

 ficial resemblance to M. sabanus, although belonging to quite 

 a different group of rats. This is M. Millleri, Jent., of about 

 the same size and with a nearly equally long tail, but which 

 may be distinguished by its coarse M. decumanus-like fur, 

 yellowish instead of rufous coloration, the less sharply-defined 

 white underside, and by the quite uniformly brown- haired 

 feet and tail. 



XXXII. — Notes on Sphingidee from the Malay Peninsula, 

 and Description of a new Species o/ Ambulyx from North 

 Borneo. By W. L. Distant. 



During the time I was collecting and receiving butterflies 

 from the Malay Peninsula as material for a recent publication 

 a considerable nunfiber of Heterocera were also accumulated, 

 which it is now proposed to work out. Of the family Sphin- 

 gidse I have received the following sixteen species; three 

 more have been described by Mr. Butler, and another two 

 recorded from Malacca by Mr. Walker. This brings the 

 list of Sphingidee found in the Malay Peninsula to twenty-one 

 species, though doubtless many more remain to be discovered.
