HAIRLESS DUIKER AND DOG, AXD BULLDOG-HEADED CALF. 245 



The veterinary attendant states that at the time of birth 

 the offspring was alive, but that owing to the birth being a 

 difficult one it was killed before it could be extracted. 



A few days later another cow crossed by the same bull and 

 in the same stable produced a six-months calf which extern- 

 ally was practically identical with the one above described. 

 It was also a male, and possessed a similar abnormal tumour- 

 like swelling at the perina^um. In the case of the first calf 

 the viscera were unfortunately removed and thrown away, but 

 the remainder of the body was handed to the Museum. In 

 the second calf the viscera were also removed, but they were 

 subsequently sent to the Museum in brine. The rest of the 

 body was inspected and seen to be externally quite similar to 

 the first calf, but it had been disposed of, and was not further 

 available for anatomical purposes. 



Viscera of the Second Calf. 



The stomach was simple, like that of a horse or pig, and 

 not like that of a ruminating ungulate. It was placed trans- 

 versely across the body, and measured about Sh in. from right 

 to left, and 2j in. from before backwards. Internally it was 

 quite undivided, but possessed prominent longitudinal ridges. 

 The distinction between a smooth cardiac portion and a 

 ridged pyloric portion, seen in the horse, was not well marked. 

 The proximal limb of the duodenum was about 7 in. in length 

 and f in. in breadth. The small intestine was much convoluted, 

 and possessed a total length of about 5 ft. The small intestine 

 was separated from the lai'ge intestine by a prominent ridge 

 forming a projecting ring. The ctecum communicated with 

 the large intestine by an aperture which occurred immediately 

 below the projecting ring [Text-fig. (1, 2.)]. 



The csecuni was short and spirally coiled, and was attached 

 by its outer surface to the small ixitestine. It was smooth, 

 and in shape and position resembled the caecum of a dog 

 rather than that of an ox. Only a portion of the colon 

 remained in the specimen ; it was smooth, with no longitudinal 

 bands of muscle.
