And Tarsius will have to be definitely removed from the 
Lemurs, as has also already been done by myself (’96,’99,’02) 
and by Wortman (03, ’04, p. 167), who unites it with monkeys 
and man in the order of the Anthropoidea, differentiated from 
the Lemurs, in addition to the characters derived from the 
blastocyst and the placenta, discussed above, by the arrange- 
ment of the ento-carotid circulation, which in the Lemurs 
more closely approaches to the peculiar plan of the Insecti- 
vores, 
Wortman’s subdivision of his suborder of Anthropoidea in 
the three superfamilies 
(a) The Arctopithecini, including as single family the 
Hapalide ; 
(b) Palwopithecini, including, besides Anaptomorphus 
and Tarsius, yet Necrolemur and (perhaps) Micro- 
cheerus ; } 
(c) The Neopithecini, man and the living monkeys, 
besides the fossil family of Adapide, 
is the embodiment of what I have stood up for since my 
publication in Gegenbaur’s Festschrift (796), and has, of 
course, my full sympathy. 
I must, however, differ from Wortman when he considers 
“the Primates a perfectly natural and homogeneous order, 
including the Lemurs, monkeys and apes, as well as man 
himself” (1. c., p. 163). I hold his suborder of Anthro- 
poidea, above named and very fully discussed in his paper 
(03), to be in reality a full-rank order, which should retain 
the time-honoured name of Primates. The two other sub- 
orders which Wortman combines with his Anthropoidea, viz. 
the Lemuridea and the Chiromyoidea, should be ranked 
together as suborders of the distinct order of Lemurs. I 
will discuss this point somewhat more fully with reference to 
the contents of the previous chapters. 
Chiromys madagascariensis has a typical diffuse pla- 
centa, of which I here give a figure (Fig. 151) taken by myself 
from a Chiromys foetus in the British Museum kindly lent to me 
for the purpose by the trustees. ‘I'his placenta, which, as dis-
