62 BULLETIN OF THE 



above, to secure priority for American work ; but with regard to the species 

 mentioned or indicated in the " Challenger " reports, hut not described, I have 

 left all such untouched, as belonging, by proper courtesy, to the English natu- 

 ralists to make known." 



A good part of the collections made in the " Blake " have already 

 been sent to several naturalists for examination, and I hope to be 

 able to publish, without too great delay, the preliminary Reports in 

 addition to fhe one of Mr. Dall printed with this letter. The Fishes 

 have been intrusted to Dr. F. Steindachner, Director of the Zoological 

 Museum of Vienna ; the Sponges, to Prof. Oscar Schmidt of Strasbourg ; 

 the Crustacea and Starfishes, to Prof. Alph. Milue-Edwards and to Prof. 

 E. Perrier of the Jardin des Plautes of Paris; the Annelids, to Prof. 

 Ernst Ehlers of Gottingen. The Crinoids, as I have stated, will be 

 sent to Sir Wyville Thomson, the Ascidians to Prof, Lacaze Duthiers, 

 the Foraminifera to Mr. H. B. Brady, and the Ostracoda to Mr. G. S. 

 Brady, both of Newcastle. In this country the Corals and Holothurians 

 will be worked up by Mr. Pourtales, the Ophiurans by Mr. Lyman, the 

 Hydroids by Mr. S. F. Clark of the John's Hopkins University, and I 

 shall take the Sea-Urchins myself. No disposition has as yet been 

 made of the Halcyonoids and Bryozoa. As the latter are not numerous, 

 it is possible that the collection does not contain many novelties. They 

 will be examined and compai'ed with the collection formerly made by 

 Mr. Pourtal6s, and described by Professor Smitt, of Stockholm.
