This species is readily distinguishable from V. pusilla by 

 its smaller size, the forearm of the adult specimen described 

 by Peters having been 35 mm. in length, and its skull, 

 measured on the plate, 20 mm. The narrow transverse shape 

 of the Inst upper molar is also distinctive and quite uniform 

 in the five examples of F. ihyone before me. 



Bassauicyon. 



Dr. Allen has recently * described a second Central- 

 American species of this genus, apparently being considerably 

 influenced to do so by his taking the Panama specimens 

 figured by Huetf as practically topotypical of B. gahhi, 

 whose original locality was Talamanca, 8.E. Costa Rica. 



But Huet's did not come from tlie north of Panama in the 

 sense of the part of Panama State nearest towards North 

 America, which would be adjacent to Talamanca, but from 

 near the town of Panama, a very different place ; for 

 Prof. Trouessart has kindly examined the original registers 

 at my request, and finds that the entry runs : — "Village de 

 Caimito, province de Chorreo [not Correo, as misprinted by 

 Huet], un peu au nord de Panama." Allowing for the bad 

 writing of M. Boucard, the collector, Prof. Trouessart thinks 

 " Chorreo " means " Chorrera," a place quite close to Panama 

 City. 



Dr. Allen assumes that no more specimens of Bassaricyon 

 have been collected than those referred to in literature, 

 forgetting that lie had seen additional specimens during his 

 last visit to the British Museum. 



As a matter of fact, the Museum now contains eight 

 examples belonging to the genus, and these appear to me to 

 belong to three types, as follows : — 



1. Skull rounded, with very convex frontal profile. General 



colour less fulvous, more greyish or brownish. 

 B. gahhi (and possibly B. richardsuni) . 



Hah. Nicaragua, Costa Rica, and N.W. Panama. Ex- 

 amples from Chiriqui in the Museum Collection may be 

 taken as representative, that locality being really very near 

 to Talamanca. 



2. Skull rounded. General colour strongly fulvous. 



B. medius, sp, n. 



Hah, Central Panama to Western Colombia.
