 eight hundred bottles. 



The Echini and Star-fishes are not so numerous, but are repre- 

 sented by very interesting forms. 



Of Crinoids, a very large collection of Pentacrinus was obtained, 

 of all ages, and probably at least two species ; also a few speci- 

 mens of Rhizocrinus, one imperfect Holopus, and a considerable 

 number of Comatulae of several species. The Holothurise are 

 also numerous and well preserved. 



The new forms in the large collection of Sponges have been 

 sent to Professor Oscar Schmidt of Strassburg, who has worked 

 up the former collections. 



In the exhibition rooms, I have only added during the past year 

 a small collection of Foraminifera, partly represented by models, 

 and part of the systematic collection of Acalephs. Also, part of 

 the Echinoderms, Polyps, and Acalephs for the North American 

 Faunal Collection.
