November 10, 1920. 



Type locality. — Curityba, Parana, Brazil. In the original descrip- 

 tion of the species T. brasiliensis, I. Geoff roy selects no single specimen 

 from Brazil as the type, but mentions seven specimens from the Prov- 

 ince of Missiones and four specimens from the district of Curityba, 

 Province of Parana. Since I have been able to examine six specimens 

 from the province of Parana, I select Curityba as the type locality in 

 order to fix the name on a definite form. 



Measurements taken by Mr. Miller in 1904 from a mounted speci- 

 men in the Paris Museum marked "Type, Brazil," are as follows: 

 Tail, 36; tibia, 13; foot, 9.4; forearm, 43.8. These measurements 

 all fall within the limits of variation of the measurements of specimens 

 from Parana, as may be seen by comparing them with the table of 

 external measurements on page 18. 



Geographic distribution. — From Costa Rica through South America 

 as far south as central Chili. 



Diagnosis. — T. brasiliensis averages slightly larger than any other 

 form in the brasiliensis group. The tibia is, with one exception, con- 

 stantly over 12.0 mm. in all specimens measured, while the total 

 length of the skuU in all but one instance is 17.0 mm. or over. The 

 color of the few skins examined is not different from that of North 

 American forms, except that some skins from Tucuman, Argentina, 

 and also some from Peru show a light sprinkling of white hairs on the 

 back. 



Measurements. — For detailed measurements see tables, pages 18 

 and 23.
