Nycticeh\i.s. malainus. While it is darker above and below than the 

 average of the peninsular animals, yet this is probably within the 

 limits of individual variation. The black blotching- on the hands and 

 feet is so irregulai'that it may be abnormal, a couple of blackish spots 

 are also found on the forearms. The brownish coloring- about the 

 ears looks more normal. 



NYCTICEBUS JAVANICUS E. Geoffrey. 



1812. Nycticebas jafanirus E. Geoffroy, Ann. du Museum, XIX, p. 164. 



Distrih ution. —Java. 



Diagnostic characters. — A small light-colored species, with well- 

 defined dorsal and face stripes, the dorsal stripe bordered by a distinct 

 gra3"ish area along neck and upper back. 



Color. — Sides of body and lower back dirty-pinkish buli'; under- 

 parts similar, but lighter; head, neck, and upper back dirty grayish; 

 dorsal stripe well marked, most pronounced in middle of back, gradu- 

 ally disappearing on the rump, blackish brown along the middle, dull 

 cinnamon posteriorlv, darker cinnamon on the head; face markings a 

 mixture of cinnamon and Isabella color, becoming light russet about 

 the ears. 



Skull and teeth. — The single skull is young and lacks the premax- 

 illa^. Temporal ridges appear to belong to the type that meet in old 

 age to form a sagittal crest. Mastoid and audital bulhv not inflated. 

 According to Anderson and Milne-Edwards the number of upper 

 incisors may be two, three, or four. 



Measurements. — See table, page .537. 



Specimens e.eamined. — One, Cat. No. 6475, Acad. Nat. Sci. Phila. 

 The specimen is labeled as having come from the Philadelphia Zoo- 

 logical Society, which throws some doubt on its reall}' having come 

 from Java. 



Remarl's. — The grayish color bordering the dark markings makes 

 this species appear quite distinct in color from other island forms. 

 With the exception of the well-defined face markings, the anterior part 

 of the animal resembles quite closely Edward's figure of Xycticehus 

 cinertus. Many authors have laid stress on the distinctness of the 

 head markings in the Javan animal, but they are not more distinct 

 than in many examples of other species except iV^. coucang and N. 

 cinerexis.
