NO. 1269. ANDAMAN AND NICOBAR MAMMALS— MILLER. 775 
gloss}' texture of the hairs, together with a very tine annulation (partic- 
ularly in mantle), imparts a faintl}^ g-rizzled aspect. Posterior half of 
back verj'^ dark brown, almost black, with here and there a hair which 
shows a trace of wood brown annulation. Tail deep burnt umber 
throughout, except at extreme base, where it shades abruptly to black 
above and to the drab wood brown of belly below. 
In other specimens the dark dorsal area is lightened to prouts brown 
(of a shade consideral)ly darker than Ridgw^a3"\s PI. in, fig. 11) and 
the tail to a pale burnt umber glossed with russet. In most cases, 
however, the color is like that of the type, or nearl}' so. 
Skull and teeth. — I can not find that the skull and teeth differ from 
those of Tupaia nicoharica nicoljarica. 
Measurements. — External measurements of type: Total length, 410 
mm.; head and body, 190; tail vertebrae, 220; hind foot, 48 (45); ear 
from meatus, 16; ear from crown, 7; width of ear, 13.4. Average of 
ten specimens from the ty^& locality: Total length, 388 (370-410); 
head and body, 176 (170-190); tail, 212 (200-220); hind foot, 47.5 
(47-49); hind foot without claws, 44.4 (43.4-45). For detailed exter- 
nal measurements see table, page 776. 
Cranial measurements of type: Greatest length, 54 (53)' mm.; ])asal 
length, 47 (46); basilar length, 46 (45); median palatal length, 28 (27.6); 
length of nasals (about), 18 (18); distance from lachrymal notch to tip 
of premaxillary, 21.8 (20.8); diastema, 5 (4.6); width of palate between 
anterior molars, 9.6 (9.8); lachrymal breadth, 18.4 (17.8); breadth of 
rostrum at middle of diastema, 7 (7.4); least interorbital Ijreadth, 
17.4 (16.4); zj^gomatic breadth, 28 (28.6); least distance from inion to 
rim of orbit, 26 (26.6); occipital depth, 12.4 (12); depth from middle 
of parietal to lower surface of audital bulla, 18 (17.4); depth of ros- 
trum at base of nasals, 8 (8); depth of rostrum at middle of diastema, 
5.8 (5.4); mandible, 37 (36); maxillary toothrow (behind diastema, 
19 (19); mandibular toothrow (behind diastema) 17 (17). 
Specimens examined.- — Seventeen, all from Little Nicobar Island. 
Remarhs. — Typical individuals representing the majority of speci- 
mens are instantly recognizable, as compared with similar material 
from Great Nicobar, by the dull, relatively lusterless, and ill-contrasted 
color of the mantle and thighs, as well as by the less yellow underparts. 
The mantle is less often outlined by a dark shade at the side than in 
the typical form. Occasionally a specimen may be found which can 
not be certainly referred to either race, but takmg the series as a 
whole the characters are readily appreciable. 
^ Measurements in parentheses are those of an adult male Tupaia nicobarica nico- 
harica.
