Notes on Fossils Obtained at Sankatv Head, Nantucket in 
July 1905. — Through the kindness of members of the Nantucket 
Maria Mitchell Association I was fortunate enough to make a suc- 
cessful collecting trip to the exposure at Sankaty Head in July of 
the past summer. By the united efforts of the party a section 
through the fossiliferous beds was laid bare and then worked 
systematically. The results of the collecting in this manner and 
also by looking over the loose material were very gratifying. The 
material thrown out in the previous year's excavating by Mr. J. 
Howard Wilson was well worked over by the rains of the previous 
winter and spring. In the small gullies at the base of this material 
small shells and crab claws were easily seen although very hard 
to see in the freshly exposed material. As a result of this search- 
ing a considerable number of small shells and crab claws were 
obtained.
