Excerpt from Illustrated Catalogue of the Museum of Comparative Zoölogy, at Harvard College, Vol. 8: Zoological Results of the Hassler Expedition, Published by Permission of Prof. B. Peirce, Supt of the U. S. Coast Survey, I. Echini, Crinoids and CoralsA preliminary notice of the Sea-urchins collected on the Hassler Expedi tion was given in the Bulletin of the Museum, Vol. III. P. 187, January, 1873. The more interesting species are here described in detail, with figures of those species which are not found in the Revision of the Echini, and which. Complement the generic representations. The material collected has enabled me to make corrections and additions to our knowledge of several of the species of Echini, and many points interesting for the geographical distribu tion of the order have been added.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
