Fig. 3.  Ungava type of throwing-stick.  The specific marks are the general outline, especially the fiddle-head ornament at the bottom; the bend upward at the lower extremity, the eccentric perforation for the index finger, and the groove for three fingers.  Collected at Ungava, by Lucien M. Turner, 1884.  Museum number, 76700.

Fig. 4.  Cumberland Gulf type of throwing-stick.  The specific marks are the broad clumsy form, the separate provision for the thumb and each finger, the bent lower extremity, and the broad furrow for the bird-spear.  Accidental marks are the mending of the handle, the material of the stick, and the canine tooth for the spur at the bottom of the square groove.  Collected in Cumberland Gulf, by W.A.  Mintzer, in 1876.  Museum number, 30013.

PLATE V.

Fig. 5.  Anderson River type.  The specific marks are the extreme plainness of form, the lack of accommodations for the thumb and fingers, excepting the eccentric index-finger hole, the poor groove for the harpoon-shaft, and the absence of a hook or spur at the bottom of this groove.  The accidental marks are cuts running diagonally across the back.  In another specimen seen from the same locality the shaft groove is squared after the manner of the Cumberland Gulf type.  Collected at the mouth of Anderson River, by R. Kennicott, in 1866.  Museum number, 2267.

Fig. 6.  Point Barrow type.  The specific marks are the distinct handle without finger grooves, the very eccentric index-finger hole, the method of inserting the spur for the shaft, and the harpoon-shaft groove very shallow above and deep below.  In the specimens shown by Mr. Murdoch there is great uniformity of shape.  Collected at Point Barrow, by Lieut.  P.H.  Ray, in 1883.  Museum number, 89902.

Fig. 7.  Kotzebue Sound type.  The specific marks are the twisted handle, the broad shallow shaft groove, and, notably, the pocket for the index-finger tip-visible on the lower side, but nearly absent from the upper side, and lying directly under the shaft groove.  In the examples before noted all the holes for the index finger are to one side of this shaft groove.  Collected in Kotzebue Sound, by E.P.  Herendeen, in 1874.  Museum number, 16235.
