To facilitate a direct comparison, some measurements of 

 other Bear-skulls from Ecuador are in this table put along- 

 sido of the figures expressing the dimensions of the two 

 skulls from Baeza. On the right side are to be seen the 

 measurements of the skull of a female Bear killed Ve 1920 

 at Gualea, on the western slopes of the Andes, altitude 5000 

 feet. This Bear has also kindly been presented to this Mu- 

 seum by Consul Söderström. 



On the left side I have taken the liberty of quoting 

 from Thomas the by him published cranial measurements 

 of his male type specimen of Tremarctos ornatus majori, which 

 is said to lead its origin from the province of Azuay, south- 

 ern Ecuador. Finally there are also the cranial dimensions 

 of an old typical male of Tremarctos ornatus from Peru, as 

 recorded by the author just quoted. 



A comparison of all these measurements is of considerable 

 interest. The first thing observed is, that the Bear from 

 Baeza has the figures expressing longitudinal dimensions 

 decidedly larger than the corresponding ones of the typical 

 Peruvian Bear. On the other hand the lättar has a broader 

 skull with larger zygomatic width and greater interorbital 

 width, but the basioccipital is broader in the Bear from 

 Baeza. Still more important is, however, that the Bear from
