SPOLIA NEMORIS. 91 
demand among the wealthier natives who have family quarrels 
to settle, and I have known exorbitant prices, with which a 
collecting embryologist could not possibly compete, to be 
stealthily paid for one specimen, for this unfriendly though 
perhaps harmless purpose. 
As will be seen, Nycticebus differs most considerably from 
Tarsius in several important respects. 
The stages of pregnancy, as studied from the unopened uterus, 
are not characterised by any very marked peculiarity. In the 
three uteri figured on PI. 9 the ovary is seen to be more or less 
concealed by a mesenterial fold, which contains the Fallopian 
tube, whereas the two horns of the uterus have a peculiar asym- 
metrical shape, being rounded dorsally and pointed ventrally. 
This latter detail, which can be easily recognised in the uteri 
that are young or in early stages of pregnancy, is of course lost 
as the swelling of the pregnant horn increases. Still, even 
then it can yet for a very long time be detected in the non- 
pregnant horn. 
In the literature on the Mammalia I do not find any other 
representation of the uterus of Nycticebus than those contained 
in Kuhl’s “ Einiges tuber die Splanchnologie von Stenops 
gracilis ” (Beitrage zur ‘ Vergl. Anatomie, zweite Abtheilung,’ 
p. 37, pl. 6, Frankfurt, 1820) ; and in Schroeder van der Kolk’s 
papers, ‘ Bijdrage tot de Anatomie van den Stenops kukang’ 
(‘Tijdschrift voor Nat. Gesch. en Physiol.,’ vol. viii, pl. 5, figs. 8 
and 9, Leiden, 1841). This latter figure is most insufficient, 
and does not in any way indicate the peculiarity just mentioned. 
Moreover in these figures other peculiarities—for example, an 
abnormal extremity of the Fallopian tube (I. c., fig. 9)—are 
represented, and a total absence of fimbria is noticed which 
does not conform to the actual facts, and which differs markedly 
from what figs. 3 and 7 teach us. V. d. Kolk’s specimens 
must have been somewhat mutilated and perhaps imperfectly 
preserved. 
The first pregnant uterus of Nycticebus which I opened was 
the object of particular expectancy. Knowing that for the 
Madagascar Lemuroids (Propithecus, Indris, Avahis) both
