Descriptions and Becords of Bees. 4 15 



Summary. 



1. The patterns of the cubs of lions and pumas are specific 



characters. These species, usually rlescribed as 

 uniformly coloured, were formerly marked as their 

 cubs arc marked and in no other way. 



2. The i)attern of lion cubs is intermediate between the 



spotted pattern of leopards or jaguars and the striped 

 pattern of tigers. 



3. From this it may be inferred that leopards (including 



jaguars), lions, and tigers are nearly related one to 

 another. 



4. On the assumption that spots preceded transverse stripes 



in evolution, it may also be inferred that the stripes 

 of tigers originated from the fusion of rosettes into 

 transverse chains, as Dr. Bonavia maintained. 



5. The pattern of i)uma cubs affords no support to the 



belief that pumas are nearly allied either to leopards 

 or lions. 



6. Rather, in my opinion, does the pattern of puma cubs 



suggest that pumas may be regarded as large self- 

 coloured representatives of one of the groups of 

 smaller species of Felis, in the same way that lions 

 may be regarded as large and otherwise modified 

 representatives of a group exemplified by leopards. 



EXPLANATION OF THE PLATES. 

 Plate XLY. 



Copy of a phototrraph of the dorsal view of a mounted lion cub in the 

 collection of the Bristol Museum, showing the formation of 

 transverse stripes from rosettes and attestiug the relationship 

 between lions and leopards on the one hand, and lions and tigers 

 on the other. 



Plate XX. 



Drawing of the flat skin of a newly born puma cub in the collection of 

 the Zoolup:ical Society of London. The unshaded area on the 

 fore part of the neck shows where the hair has been rubbed 

 away. Since the tail was absent from this skin, the drawing of 

 that organ was copied from the example in the Museum of the 

 Clitton Zoological Gardens.
