partially albinistic. It has the head from the base of the rostrum back nearly 
half the distance to the ear opening, white, a white spot on the right side in 
front of the shoulder, another on the left side behind the shoulder, and an irregu- 
lar series of marks on the rump. It is evident that such marks are of no taxo- 
nomic value in the present case. No. 7,398 M. C. Z. is a topotype from Mt. 
Arfak, and is preserved in alcohol. The face, forehead, limbs, and belly are a 
dark Vandyke brown, darkening to seal-brown over the dorsal region. The 
fur is thick and woolly, but the spines project conspicuously above it. These 
spines are uniformly blackish with white tips, are short on the occiput but large 
over the back, shoulders, and caudal region where the longest reach nearly 
37 mm. They encroach slightly on the sides of the venter, but are few and 
scattered on the belly. Thomas (1907a) says that in bruzgnii the belly is with- 
out spines throughout but this is hardly the case in any of the specimens I have 
examined. In its possessing black spines this specimen resembles “‘nigro- 
aculeata,”’ but it is not so thinly haired as Rothschild describes. The flattened 
character of the spines in this supposed race is unquestionably the result of 
wear. For in an old specimen, M. C. Z. 12,414, many of the dorsal spines are 
worn quite to the small hollow center and have become beveled off nearly flat 
on their dorsal surface. This old specimen consists of a skin and skeleton from 
Fak Fak, New Guinea. The hair and spines are greatly worn and so scattered 
that the skin is everywhere visible. The general color of the hair on the fore part 
of the head is a pale buffy, but on the dorsal part of the body the scattered 
bristles are blackish or blackish brown. Those on the ventral surfaces are a 
more decided brownish, near Prout’s brown. On the fore imbs are a number of 
grizzled whitish hairs with the brown. Of the spines, almost all are white 
throughout but a few, on the shoulders, back, and hips are blackish, with pale 
bases. The ventral spines are short and are distributed from the axilla nearly 
to the groin. They are arranged in rather definite curved rows, the most an- 
terior passing posteriorly and dorsally, the later rows curving laterally from the 
axilla, then in towards the groin. These ventral spines reach to within 25 mm. 
of the midline. This large specimen is apparently identical in general char- 
acters with that described by Thomas (1907a) as Acanthoglossus goodfellowi 
from the island of Salawatti. There can be little doubt that both are simply 
old animals with the hair either much worn or partly shed. Of much interest 
in our specimen is the fact that among the large worn spines are scattered other 
smaller ones, sharp-pointed and unworn, that appear to be new spines coming in. 
In 12,415, M. C. Z., an adult also from Fak Fak, the spines are large, stout,
