Summary. 



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



characters. These species, usually described as 

 uniformly coloured, were formerly marked as their 

 cubs are marked and in no other way. 



2. The pattern 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 puma cubs affords uo 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 



snggest that pumas may be regarded as large self- 

 coloured representatives of one of the groups of 

 smaller species of Felts, 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 pliotograpli 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 attesting the relationship 

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

 on the other. 



Plate XX. 

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

 the Zoological Society of London. The unshaded area on the 

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

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

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

 Cliltou Zoological Gardens.

This species was described fiom the female. Mr. 8. A. 

 liolnver collected five males at Florissant, Colorado, June 15 

 to July 6, 1907 ; one was at flowers of Erigeron. The male
