REPORT OF NATIONAL MUSEUM, 1912. 57 



The division of mineralogy and petrology received by transfer 

 from the Geological Survey six lots of type specimens of plumbo- 

 jarosite, ferritimgstite, beaverite, hinsdalite, paigeite, and hulsite, 

 and also two type specimens of crystallized variscite from near Lucin, 

 Utah. A showy specimen of tiirquois, unique in representing the first 

 known occurrence of this mineral in a crystallized condition, and of 

 special interest as furnishing the type material for a chemical and 

 crystallographic investigation by Mr. W. T. Schaller, of the Geo- 

 logical Survey, was received as a gift from Mr. J. H. Watkins, of 

 Washington. Specimens of neotantalite, tourmaline, villaumite, 

 grandidierite, autunite, danburite, spodumene, caesium beryl, all 

 interesting as representing minerals or localities new to the collec- 

 tion, were obtained from Mr. Schaller in exchange. The gem collec- 

 tion was enriched by four beautiful moss agates from near Glendive, 

 Mont., the gift of Dr. L. T. Chamberlain, and by a few purchases 

 made in Germany and England by Dr. Pogue. The latter included 

 a carved turquois charm, a lapis lazuli carving, a Chinese clasp set 

 with jade and pink tourmaline, an opal carving, a Ceylon moon- 

 stone, and necklaces of rose quartz, amethyst, and opal. 



Collections of petrological interest were received from the Geo- 

 logical Survey, as follows: Eighty-four specimens illustrating the 

 geology and ore deposits of the Breckenridge district, Colorado, as 

 described by Mr. F. L. Ransome in Professional Paper No. 75; 71 

 rock specimens illustrating the geology of the Taylorsville district, 

 California, as described by Mr. J. S. Diller in Bulletin 353 ; and 70 

 specimens illustrating the rocks and ores of the Tonopah district, 

 Nevada, as described by Mr. J. E. Spurr in Professional Paper No. 42. 



By far the most important accession of the year, and one of the 

 most noteworthy ever received by the department of geology, con- 

 sisted of the collection of fossil echinoderms assembled by and still 

 belonging to Mr. Frank Springer, of East Las Vegas, N. Mex., which 

 he has deposited in the Museum and has permitted to be made avail- 

 able for both study and exhibition. Comprising upward of 75,000 

 specimens, it contains many hundreds of types and constitutes the 

 most complete series of the fossils of this group in the world. The 

 collection has been installed for reference and study in one of the 

 large laboratory rooms in the new building, where Mr. Springer is 

 continuing his investigations. Mr. Springer also presented to the 

 Museum about 600 Middle Ordovician fossils from eastern Tennessee, 

 including many choice specimens of sponges and graptolites. 



Most notable of the collections in invertebrate paleontology de- 

 posited by the Smithsonian Institution was a series of 126 types of 

 Cambrian fossils illustrating studies by Secretary Walcott on the 

 Middle Cambrian faunas of British Columbia. Of less importance
