488 DR. J. MURIE ON SAIGA TARTARICA. [June 9, 
Saiga, and you have found no such protuberances, such is probably 
the explanation. However, I am not quite sure as to the species of 
Antelope: I think Mr. Bartlett had some doubt about it.” 
In the well-conditioned male, as in Pallas’s specimen, the mesen- 
tery was loaded with fat, which in great part covered the stomach 
and the convolutions of the gut. 
As regards the extent of the intestinal tube, itis best expressed in 
the subjoined tabular view.

The lesser gut is throughout narrow. ‘There is no ileo-colic sac- 
culated gland as in the Giraffe; but the ileo-czecal orifice has a 
broadish valvular fringe. The ceecum is simple, and neither it nor 
the colon is provided with longitudinal fibrous bands. Close upon 
two and a half feet of the czecal appendage and the great intestine 
have a diameter of about a couple of inches; the remainder of the 
tube is of moderate calibre, with a very slight widening towards the 
rectum. The intestines describe gyrations and are spirally coiled. 
My admeasurement of the intestines do not accurately coincide 
with those of Pallas; but this may be accounted for by variation 
in the animals’ ages, or, mayhap, by reason of one being wild, the 
other confined and fed differently. Assuming that his observations 
and those of Cuvier * are correct, the intestinal tract is nearly equiva- 
lent to similar-sized Antelopes’ and disagrees with that of the Sheep. 
Entire intestine exceeds the body in length :—13°1 times, Stag ; 
13°6, Saiga; 14:9, A. cervicapra; 15:0, A. yutturosa ; 28°1, Sheep. 
The small intestine is in excess of the great :— L'4 times, Stag ; 
2°3, A. gutturosa; 2°6, Saiga; 2°7, A. cervicapra; 3°3, Sheep. 
The Sheep-like liver is transversely broad, almost destitute of in- 
cisions ; what answers therefore to a large left lobe is medianly imper- 
fectly defined. The slight median notch and its round ligament are 
close to the fundus of the gall-bladder, thus cutting off from its due 
share of the anterior border the homologue of the lobus quadratus; 
the latter is moderately wide and triangular. The bayonet-figured 
caudate lobe is four inches long, and extends freely beyond the right 
border. A lobus Spigelii is but scantily developed. The rela- 
tive diameters of the liver in the male Saiga were 10 inches trans- 
versely and 6 antero-posteriorly, in the younger female 8 and 43 
inches respectively. As in the Bovide, the hepatic substance is soft, 
finely granular, and smooth-surfaced. 
The short roundish gall-bladder is of moderate dimensions, its 
fossa small and shallow; the fundus, as in Bison americanus, reaches 
quite beyond the free border of the liver. The cystic duct and
