BASSARISCYON GABBI ORINOMUS, subsp. nov. 



Type from Cana (altitude 1,800 feet), in the mountains of eastern 

 Panama. No. 1 791 57, male adult, U. S. National Museum (Biologi- 

 cal Survey Collection), collected by E. A. Goldman, March 10, 1912. 

 Original number 21474. 



General characters. — Similar to gabbi in size, but color more 

 tawny or paler fulvous, less brownish ; skull with very long postorbi- 

 tal processes, broad basioccipital and small audital bullae ; differing 

 from the other species mainly in cranial details. 



Color. — Upper parts in general pale fulvous darkened along me- 

 dian line of dorsum by black-tipped hairs, becoming grizzled grayish 

 on top of head and face ; under parts varying from pale orange buff 

 to very pale buffy yellow ; upper base of ears distinctly blackish in 

 some specimens, fulvous in others ; feet varying from grayish ful- 

 vous to grayish brown ; tail varying shades of pale fulvous, darker 

 above than below, becoming brownish or blackish toward tip and 

 more or less distinctly annulated along median portion. 



Skull. — In general outline about as in gabbi (frontal profile con- 

 vex, not flattened as in allcni) ; basioccipital broader ; postorbital 

 processes longer, more projecting; audital bullae decidedly smaller; 

 dentition as in gabbi. Similar to that of richardsoni in development 

 of postorbital processes, but basioccipital broader and audital bullae 

 smaller. 



Measurements. — Type : Total length, 820 mm. ; tail vertebrae, 419 ; 

 hind foot, 86. An adult female topotype : 840 ; 450 ; 84. An old 

 adult male from Mount Pirri : 865 ; 457 ; 88. Skull (type) : Greatest 

 length, 85 ; condylobasal length, 85 ; zygomatic breadth, 56.2 ; inter- 

 orbital breadth, 18; breadth across postorbital processes, 35.8; palatal 

 length, 46.5 ; upper molariform tooth row, 23.7. 



Remarks. — The known forms of Bassariscyon seem to agree 

 closely in essential characters and may prove to be geographic races 

 all assignable to a single widely ranging species. As in many other 

 groups cranial modifications are more reliable than color as dis- 

 tinguishing characteristics. No material showing the color of gabbi 

 at the type locality i^ available, but a specimen from near Gatun, 

 Canal Zone, agrees very closely in cranial details with the type and 

 coming, as it docs, from within the same general faunal area may be 

 regarded as typical. In this specimen the face is gray as usual in 

 the genus, and not at all like Huet's x figure of the animal from 

 " Caimito, dans la province de Corren, mi pen an nord de Panama"
