long to this species. They are a little smaller but otherwise do not 

 differ essentially from the typical form. 



Family PINACE^S 



Picea harrimani sp. nov. 

 pi. xxii, figs. 3, 4. 



Cones cylindrical, long and relatively slender, rounded at apex; 

 scales large, in seventeen or more whorls, about four or five showing 

 in each row, regularly rhomboidal in shape ; apparently without mark- 

 ing or obvious thickening. 



The specific name is given in honor of Mr. E. H. Harriman, the 

 patron of the Expedition. 



This splendid species is represented by four examples, two of which 

 are here figured. The largest of the four (pi. xxii, fig. 4) is preserved 

 for a length of 10 cm. and when perfect was probably fully 12 cm. 

 long. At the base it is 2.5 cm. broad, and it is 2 cm. broad near the 

 apex. The scales in the lower portion are about n mm. in length, 

 and 6 or 7 mm. in short diameter. They are slightly smaller in the 

 upper part of the cone. 



The smallest example, also figured (pi. xxii, fig. 3), has about 9 

 cm. of the length preserved, but the base is evidently lacking. It 

 is much narrower than the others, being only 1.5 cm. broad. The 

 scales are smaller, being about 7 mm. in long, and 5 or 6 mm. in short 

 diameter. It is possible that this specimen may represent a different 

 species. 



Of the two other examples the best preserved shows only the upper 

 portion. It is of about the same size as the upper portion of the largest 

 one figured. The other is preserved nearly entire but does not show 

 the scales well. It is 7-5 cm - i n length and about 2 cm. in width. 

 All of the cones are slightly curved, this last mentioned one in par- 

 ticular. 



Of course we are here considering only the impression of the outer 

 portion of the cone, but the actual substance is represented by a coaly 

 mass i or 2 mm. in thickness, which has been mostly crumbled away 

 in handling. 



It was at first supposed that these were cones of a Pinus allied to 

 P. strobus L., but after further consideration it appears more probable 

 that they belong to the genus Picea. In a general way they are similar 

 to P. sitchensis Carr., the Alaska spruce, but are narrower and 

 longer than is usual in this species. The edges of the scales in the
