same way as those of the specimens from Guiana. The same 

 is also said to be the case with Goldman 's »CA. panamensis» 

 in strong contrast to the condition shown by Burmeister's 

 fig. of the skull of a Chironectes from Southern Brazil in his 

 »Fauna Brasiliensis» (Taf. XI, fig. 3). If there is no mistake 

 about this latter figure, it undoubtedly represents a separate 

 species. But on the other hand I am not able with the 

 present material to find any specific difference between the 

 Chironectes of Ecuador and the typical one from Guiana. 

 I fail also to see the supposed distinguishing characteristics 

 between Goldman's form and the typical one. Goldman's 

 description appears chiefly to point out the differences with 

 regard to cranial dimensions between his specimen and Bur- 

 meister's figure. He also says that his specimen differs from 

 »C. minimus of Guiana» by having »much longer, evenly 

 tapering and posteriorly pointed nasals». The first of these 

 supposed characteristics is not correct, as specimens from 

 Guiana may ha ve quite as long nasals as Goldman's type; 

 and the two latter characteristics referring to the shape of 

 these bones are just as well shared by the true C. minimus 

 from Guiana. 



Chironectes is known in Ecuador under the name of 

 »Raposa del Agua». It lives, according to Consul Söder- 

 ström, in streams at an altitude from 5,000 down to 3,000 

 • feet.

This female specimen has a very wide marsupial pouch, 

 which is more strongly hairy in the middle and posteriorly 

 than laterally.
