positions of the intermediate teeth are most various, sometimes they are evenly 

 spaced out between p l and p 4 , but sometimes they are crowded together. The 

 teeth in corresponding ordinal positions do not always stand at the same levels 

 ou the two sides. 



*377. Phalanger maculatus: in this species the small premolar ("p 3 ") between upper 

 p 1 and p 4 is generally absent, and in the lower jaw there are usually only two 

 "intermediate" teeth. The following table shews the variations seen in 58 skulls 

 and 7 lower jaws wanting skulls (including 43 l Leydeu skulls described by 

 JENTINK, 7. c.). 



1 Not including the case, Leyd. Mus., 153 (Jentink, /. c., p. 91), in which the 

 " small" upper premolar is stated to be absent as an abnormality. As p 3 is usually 

 absent in the species, probably this refers to p 1 .
