212 MISS K. F. LANDER ON THE 



between the quadrate and right lateral lobes, extending for some 

 distance below the inferior margin. The bile-duct is highly 

 valved. The gall-bladder thus seems distinctly different in form 

 from that of Ooibos ; it is also situated ratlier nearer to the right 

 margin than in the Musk-ox. On the whole it is more like that 

 of Bos or Connozlupies. 



The testis is oval, or, with the epididymis, spindle-shaped. 

 The total length of the testicle is 85 mm., of which 21 mm. 

 represents globus minor and 8 mm. globus major. The width is 

 40 mm. and thickness 30 mm. The head of the epididymis 

 enwraps the anterior free border of the gland for the upper half 

 of its length. It is only connected with the tunica albuginea of 

 the testis around its periphery ; the rest of the expanded head 

 can be separated from the testis by tearing the la.x areolar tissue 

 between them. The organ is enclosed in a thick tunica vaginalis

of the usual type, reflected on to the epididymis along the whole 

 length of its head and body. The globus minor forms a free 

 bulbous projection, 20 mm. in breadth, 15 mm. in depth and 

 thickness. The epididymis (in formalin) is sa,lmon-pink in colour, 

 marked by numerous very tortuous superficial veins. The tunica 

 albuginea is bluish white ; the gland shells out of this capsule 

 with the greatest ease, being sepai'ated from it liy a number of 

 large tortuous veins which run mainly in a longitudinal dii'ection 

 and make marked grooves on the sui'face of the soft brown testis. 

 The gland and capsule are only connected by a very small strand 

 at the vipper pole. (Text-fig. 5.) 



The vas deferens ascends beside the body of the epididymis, 

 accompanied by two large veins. Above the capvit it is joined 

 by a large pampiniform plexus, forming a spermatic cord 17 mm. 

 in thickness.
