162 PROF. ST.-GEORGE MIVART ON THE ZLUROIDEA. [Feb. 7, 
its inner cusp is much larger relatively ; it is Ai the largest 
tooth, and has three roots. 7M? j is shaped like @ ——, but is smaller, 
with two outer cusps and one large inner cusp ; it has two roots. 
pa 1s broader in proportion to its length and has less talon, but a 
more marked anterior tubercle. 3,5 is much broader in proportion 
to its length, and itscusps are less pointed and prolonged. Its talon is 
raised to the level of the front part of the tooth, and torms the tooth’s 
hinder half with four small cusps arranged in a semicircle, while the 
front half of the tooth bears three larger cusps, one foremost and the 
other two side by side. ;,, is quinquecuspidate, with two large 
cusps in front (not side by side), and three smaller ones behind 
arranged in a semicircle. 
Comparing tle deciduous teeth with those of Viverra, I fin 
with less talon, 2® (the deciduous sectorial) with a_ relatively 
smaller internal cusp and with the fourth cusp a little smaller. 
This tooth is decidedly more sectorial than is the permanent sectorial 
tooth, its posterior cusp being relatively larger. ?-* is much like 
that of Viverra, but is rather more quadrate. 55-5 and p>, have less 
talon than in the Civets. ;-; is more sectorial than ha cee 
sectorial tooth, and is very like that of the Civet, except that its 
talon is rather smaller and the tuberosities upon it (especially the 
innermost one of them) less developed. 
As examples of the considerable differences in the forms and sizes 
of the teeth in different species or races, I may perhaps be permitted 
to remark that the British-Museum specimen called P. macrodus 
by Dr. Gray well merits its name fr° a the large size of its teeth’. 
There is no skin of this species in the collection; and its habitat is 
unknown. + are very small in the skulls named P. larvatus, 
P. grayii, and P. lanigera in the national collection ; and they are 
rather small in P. zeylanicus and P. bondar. = (the sectorial 
teeth) are very sectorial in character in the forms named P. herma- 
phroditus, P. bondar, and P. lanigera. They are, on the other 
hand, more quadrangular and very unsectorial in form in P. macrodus, 
P. nigrifrons, P. larvatus, P. grayii, P. philippensis, P. zeylanicus, 
P. leucomystax, and P. fasciatus. 
In the Museum of the Royal College of Surgeons there is a skull 
(No. 4304 s) in which = are entirely absent. It comes from Nepal. 
In the British Museum there is also a skull (No. 1546), which 
was purchased from et so pabaeels Society and said to have come 
from Manilla, in eer = are also entirely pasar But the 
Manilla skull has 2-4 and “:! Mt ! more quadrate and F:3 much thicker; 
also 3,4 1s wider and ue 18 larger; and is wider and more

2 On the left Sie of the skull there are two small holes in the place where —— 
would be were it present. These holes, however, look more like small fractures 
or some pathological condition than like alveoli.
