HAIKLESS DUIKEK AND I)0C4, AND BVLLDOG-HEADED CALF. 247 



of elongated shape and broader at the inner end. The great 

 omentum was loaded with narrow bands of fat. 



The kidneys were placed norinally, the right being at a 

 slightly higher level than the left, and covered anteriorly by 

 the caudate lobe of the liver. The kidneys, measuring 1| in. by 

 If in., were perfectly smooth in outline like those of a dog, 

 and internally the pelvis was not divided up by lobes of 

 medullary substance or pyramids [Text-fig. (3)]. 



The heart appeared quite normal in structure. The lungs 

 were also normal, consisting of four lobes on the right and 

 three on the left. 



Skeleton of the First Calf. 



The skull exhibited great modification. The pre-maxilla3 

 were short, and the nasals were very greatly reduced, being 

 represented by small, somewhat rounded bones (PL XIII, fig. 

 1). The mandibles projected nearly two inches in front of 

 the end of the pre-maxillte, and could not bite on them. The 

 frontals were relatively large and very convex, thus causing 

 the cranial cavity to be globular. 



A true palate was completely absent, there l)eing no 

 palatal portions of the maxillas and palatines. A median, 

 well-developed vomer was present. On account of there 

 being no palate the nostrils opened direct into the cavity of 

 the mouth (PI. XII, fig. 3, i.n.), and the maxillo-turbinals 

 (m.t.) and ethmo-turbinals (e.t.) formed the roof of the front 

 portion of the mouth. Mesethmoid, presphenoid, and basi- 

 sphenoid could be distinguished. The periotics extended 

 internally to the middle of the floor of the skull, and 

 there they took the place of basioccipital. The exoccipitals 

 showed no condyles, and the foramen magnum was placed 

 somewhat out of the middle line. The tympanic bulla and 

 auditory meatus were flattened. A stylo-tympanic process 

 (6'. p.), and a paroccipital process {j)-}^-) of the exoccipital can 

 be seen in PI. XIII, figs. 3 and 4. 



The hyoid was represented by a short stylo-hyal, which
