Mountain. Whether these three forms will eventually be ranked 

 as species or eurekensis and handi as subspecies of hemphilli can- 

 not be determined definitely until further collections are made 

 in Nevada and western Utah. At the present time, there is no 

 evidence of intergradation, yet the territory where such evidence 

 would be looked for is wholly unexplored. 



Some hundreds of specimens were collected. There is slight 

 variation in sculpture, but very little in form.

A SUMMER'S COLLECTION AT FRIDAY HARBOR, WASHINGTON. 



BY T. S. OLDROYD. 



Mrs. Oldroyd and myself had the pleasure of spending our 

 vacation at the marine biological station of the University of 

 Washington at Friday Harbor, San Juan Co., Washington. 

 This group of islands, so wonderful in their wild beauty, is situ- 

 ated between the Strait of Fuca and the Strait of Georgia, north 

 of Port Townsend. The San Juan group comprises more than 

 100 islands of varying sizes, the most important being San Juan, 

 noted as having been the scene of the last struggle between the 

 British and Americans in the boundary-line dispute from 1852 

 to 1872; the ruins of the old English camp and blockhouse still 

 remain near Roach Harbor. Friday Harbor, the chief town of 

 the islands, is the county seat of San Juan Co. which includes 

 all the islands of the group. The town is situated on a beauti- 

 ful bay and is the shipping-point for a large area of unsurpassed 

 agricultural land. They have also one or two large salmon 

 canneries. The islands are nearly all high and prominent and 

 covered with a dense growth of trees, mostly fir. Mount Con- 

 stitution on Orcus Island is the highest point. From its sum-
