One specimen, an adult male (Cat. No. 154293), from Balik Papan 

 Bay, is apparently indistinguishable from specimens of Sciurus bor- 

 neensis in the U. S. National Museum collection from North Borneo.

Measurements of squirrels. 



RATUFA EPHIPPIUM (Muller). 



1838-39. Sciurus ephippium Muller, Tijdschr. Natuurl. Gesch. Physiol., vol. 5, 

 p. 147. 



Doctor Abbott secured seventeen specimens, practically topotypes, 

 of R. epliij^pium from the region of Klumpang and Pamukang bays. 

 Muller's figure 3 is an excellent representation of this species as 

 shown by unbleached specimens of the present series. The side of 

 head and top of nose in the plate, however, are too "red." In Doc- 

 tor Abbott's specimens those portions of the head are similar in 



1 Collector's measurements. 



2 Measured by writer after relaxing in water for 24 hours.
