NO. 5 MAMMALS OF PANAMA — GOLDMAN 55 



Bangs (1902, p. 19) listed specimens collected by W. W. Brown, 

 Jr., at Bugaba and Divala. Allen (1904, p. 56) provisionally referred 

 to this form nine examples taken by J. H. Batty of which six were 

 from Boqueron and three from Parida Island. The latter series 

 apparently represent the form more recently described as Philander 

 laniger nauticus. Of the general collection he says : " No two of 

 the Chiriqui specimens are alike in coloration ; all but one distinctly 

 show the pale gray median stripe over the shoulders seen in derbiamis, 

 but with varying distinctness from very clear and strong to sub- 

 obsolete, while the sides of the neck and shoulders and the middle 

 dorsal region are rufous, varying in different specimens from light, 

 clear rufous to dark, almost chestnut rufous. The other specimen 

 (one of the Parida Island series) has the whole upperparts bright, 

 nearly uniform rufous, even to the proximal half of the forelegs and 

 the entire hind legs, with no trace of the gray stripe on the shoulders." 



As at present known this subspecies may be assigned an indefinite 

 range near the arid Pacific coast in western Panama, but until more 

 material is available its exact relationship to neighboring forms 

 cannot be determined. 



Specimens examined : Boqueron, 3 1 ; Bugaba, 4 2 ; Divala, 2? 



PHILANDER LANIGER NAUTICUS Thomas 



Insular Woolly Opossum 



Philander laniger nauticus Thomas, Ann. Mag. Nat. Hist., Ser. 8, Vol. 12, 

 P- 359, October, 1913. Type from Gobernador Island, off south coast 

 of Panama. 



According to the description this insular race is most nearly allied 

 to Philander I. pallidus of the adjacent mainland, to which the 

 specimens on which it is based were formerly referred by Thomas 

 (1903a, p. 42). The general color is given as " sayal brown." The 

 grayish withers mark or median stripe between the shoulders in 

 P. I. derbiamis and P. I. pallidus is said to be imperceptible. 



Philander I. nauticus described recently was based on four speci- 

 mens from Gobernador (type locality), Brava and Cebaco, all small 

 islands close to the southwestern coast of Panama. Under the name 

 Caluromys laniger pallidus, Allen (1904, p. 56) recorded three speci- 

 mens from Parida Island which are probably referable to this race, 

 although one only lacks all trace of the shoulder stripe.
