PLATE XVI. 



(Mason. Thro wing-sticks.) 



Fig. 20. Unalashkan throwing-stick. It would be better to call this form the 

 Southern type. The noticeable features in all our specimens are the 

 parallel sides, the hard material, thinness, the carving foi»the fingers, but 

 above all the reappearance of the eccentric cavity for the index finger. 

 This cavity is not a great perforation, as in the Point Barrow type, but an 

 eccentric pocket, a compromise between the Northern cavity and that of 

 the East. Collected by Sylvanus Bailey, at Unalashka^ in 1874. Museum 

 number, 16076.
