172 Description of the Plates. 



V. Liver ; the line abutting upon its left lobe. 



w. Omentum or epiploon, a process of the peritoneum peculiar 

 to mammalia. 



X. Coecum. The entrance of the small intestine into the eoecum 

 is not seen, but we may observe that the coecum becomes 

 smaller in calibre where it is bent on itself superiorly. It 

 passes thus into the Marge intestine/ which does not 

 however contrast so markedly either in its relative shortness, 

 or in the thickness of its walls, or in its calibre with the 

 ' small intestine/ in the Rodentia, as in many other orders. 

 These omnivorous Rodents, and also the Sciuri, have smaller 

 coeca than the Rodents which live on less nutritious and 

 coarser food and have rootless molars. 



x. Convolutions of intestines. 



1/. Upper end of left cornu of pregnant uterus, passing into the 

 Fallopian tube, which together with the ovary fills up the 

 space between this convolution of the uterus and the kidney. 

 The ovary and tube are connected by a ligament to the 

 peritoneum covering the diaphragm, the ' ligamentum 

 diaphragmaticum ' connected with the 'Wolffian body^ 

 in the foetus. 



y. Lower portion of same uterine cornu distended with foetuses. 



z. Bladder contracted into a conical shape and receiving the 

 ureter at its base on the left side. 



z. Outlet of urinary organs through a perforated clitoris distinct 

 from the vagina. 



7r. Rectum. 



A. Flexor muscles of the tail, which arise from the internal surface 

 of the pelvic bones. 



h. Anterior portion of ilium, the posterior part of which has been 

 removed, together with the pubis and ischium. From its 

 internal surface the caudal flexors are seen to take origin, 

 and in front of them and in a line with the point on which 

 the letter 8 is placed, the cut end of one of the great veins 

 returning blood from the hind limb is seen. 



The following peculiarities in the tegumentary system deserve 

 notice : — the absence of hair from a part of the anterior portion of 

 the snout, the so-called 'muffle,^ in which we see the orifices of
