Book excerpt: Excerpt from Mollusca of the Southwestern States, Vol. 1: Urocoptidae; Helicidae of Arizona and New Mexico In these papers the mollusks collected by Mr. James H. Ferriss and the writer in the expedition made in 1903 and by Mr. Ferriss in two visits to Arizona in 1902 and 1904 will be discussed. The present contri bution deals chiefly with Mr. Ferriss' researches in Arizona, where an extraordinarily rich and varied snail fauna was found in the canyons of the Chiricahua and Huachuca Mountains. In the study of these mate rials I have worked over many specimens received from the late E. H. Ashmun, who first made known to us the richness of the Arizona snail fauna, and from Prof. T. D. A. Cockerell, Whose unceasing labors on the fauna and flora of New Mexico are familiar to all naturalists. The treatment of the genus Ashmunella has been made practically mono graphic. It is unfortunate that no good t0pographic survey of southern Ari zona has been published. It is extremely difficult at present to deter mine some localities given by previous naturalists, or to clearly indi cate the positions of those explored by Mr. Ferriss. The accompanying sketch of the canyons explored in the Huachucas makes no pretensions to cartographic accuracy beyond showing the relative positions of the localities mentioned in the text. From Fort Huachuca to Ramsey Canyon is 10 miles; to Carr Canyon 14, and to Miller Canyon 20 miles. Manilla mine is 6 miles from Fort Huachuca. The range is about 30 miles long and 6 wide.

These names range in taxa from those above the family level to subspecies, varieties & forms. This work had its inception when the authors found it necessary to ¿card out¿ the new names which Pilsbry had instituted so that these names might be used in their own current problems of research in the field of malacology. As time went on, this catalogue increased in size & became a source of information to the staff. Its publication has make available a large file of data not easily located elsewhere. He introduced 5,680 names over a period of 75 years; he introduced more names than any other student in the field of malacology.
