_Lozenge points (pl. 22, h, i, l-u)._--Numerically this group constitutes the largest class of the small projectile points. Were a larger series present, some refinement of types might be attempted. Of the fourteen specimens, some tend toward diamond shapes, whereas others border small leaf or stem forms. Lengths range from 2.5 cm. to 4.1 cm. Materials used are obsidian, basalt, chert, and quartz. _Large Blades and Large Points_ The large blades and points collected this season show some variation over those of last year, both in finishing technique, form, and material. Frequently, for lack of established terminology, it is difficult to distinguish between what might be termed a chipped knife, leaf-shaped blade, or a coarsely made projectile point. We attempt only a rough breakdown between blades and large points, either of which if hafted could serve the purpose of a knife. All specimens are illustrated and may be judged by the observer. Described below are only those additional specimens collected this year. For full details the 1950 report should be consulted. _Large blades (pl. 21, a-g)._-- 1. This specimen comes from a depth of 48 to 54 inches, marking the deepest level from which any blade was taken. Though it shows an old break, enough remains to offer a computed length. The form is leaf-shaped and probably pointed at both ends. Computed length, 9.2 cm.; width, 4.6 cm.; thickness, 1.2 cm. Material is basalt (pl. 21, _b_). 2. Basal half of what was probably a leaf-shaped blade. Incomplete length, 4.5 cm.; width, 5.4 cm.; and 1.4 cm. thick. Material is basalt (pl. 21, _c_). 3. Larger half of a basalt blade, showing some attempt to reshape the broken margin. Incomplete length, 7 cm.; width, 4.5 cm.; and 1.5 cm. thick (pl. 21, _a_). 4. This chert specimen exhibits the best flaking technique of any large blades from the Tank Site. Compared with the patinated basalt examples, considerable contrast exists. Typologically this specimen is similar to forms typical of the Hunting Culture of the Santa Barbara coast. Because of its shallow position (6-12 inches), lack of patination, and flaking technique, we have assigned it to Phase II of Topanga. The form is a willow leaf with slightly serrated edges. Length, 14.9 cm.; width, 3.4 cm.; and 1.5 cm. long. Material is a dark-brown chert (pl. 22, _a_). _Large points (pl. 21, h-l; pl. 22, b)._-- 1. This specimen, like the blade above, also deviates to some degree from other large points. It is composed of an unaltered obsidian and comes from the 0-to-6-inch level of the deposit. Because of its shallow depth and contrastive nature, it has been assigned to Phase II. The form is leaf-shaped, being more pointed at one end. Length, 7 cm.; width, 3 cm.; and 1.3 cm. thick (pl. 22, _b_).
