Abstract

The collections of crinoids and sea urchins made by the University of Iowa's Bahama Expedition in 1893 were placed in my hands for study and identification. No collection of holothurians ,vas made by the Expedition, while the sea-stars and brittle-stars have been reported on by Professor A. E. Verrill (Nat. Hist. Bull., V, 1 and VII, 1). To complete the account of the Echinodermata, therefore, it is desirable that a report be made on the collections turned over to me. While there is no close relationship between the crinoids and echinoids (indeed they represent quite different lines of evolution from a presumably Cystid stock), it is most convenient to embody my notes on the two groups in a single report.
