12. Sciurus irroratus (Gray). ? 



Macroxus irroratus Gray, Ann. and Mag. Nat. Hist., 1867, XX, p. 431. 

 (Upper Ucayali River, Brazil.) 



One specimen (12,725, Coll. A. N. S. Phila.), male, procured in the 

 Pagma forest, July 11, 1911, is perhaps referable to this species, 

 though no suitable material is available for comparison. 



Length 330, tail 152, hind foot 50, ear 20. 



"Squirrels were reported by the natives to be in the forests about 

 Huigra from 4,000 feet and upwards, but we saw none until we 

 penetrated the Pagma forest above Hacienda Jalancay, 6,000 to 

 7,000 feet. They were exceedingly rare, however, even in this 

 forest. I saw one, after the specimen secured was taken, in an orange 

 grove near the Casa, 1,500 feet lower down. I can state nothing 

 about their habits, not having personally observed them in life. 

 No other species of squirrels were observed in our wanderings." 

 (S. N. Rhoads.) 



13. Sciurus hoffmanni soderstromi suljsp. nov. 



One specimen (No. 12,726, Collection Academy of Natural Sciences 

 of Philadelphia), from Mt. Pichincha, November, 1903, collected by 

 L. Soderstrom. 



While a member of the yS. hoffmanni group, this specimen is much 

 more rusty-red especially across the shoulders and on the fore legs 

 than any specimens I have seen from Costa Rica or any in a con- 

 siderable series with which Mr. Osgood has compared it in the Field 

 Museum. In other respects it does not seem to differ. 



I find no name applicable to this form and would propose that it 

 be called Sciurus hoffmanni soderstromi , in honor of its collector,
