place ultimately explanatory notices in the room as a guide to 

 students. The duplicates have been partly sorted ; a liberal 

 portion .of those too unsightly for exhibition or exchange, 

 have been set apart for use in the department of instruction. 

 Sets representing the principal families have been distributed 

 to the normal schools of the State, to be used in connection 

 with similar sets from the other departments of the Museum, 

 in illustrating the lectures on natural history. 



In this work I have been greatly assisted by Miss Hyde, 

 who has mounted and arranged a large number of specimens, 

 and made a card catalogue of those on exhibition. 



The systematic collection of Ophiuridse and AstrophytidsB 

 has been mounted and placed on exhibition under the direc- 

 tion of Mr. Lyman, who has also prepared, for publication in 

 the Illustrated Catalogue of the Museum, the species of these 

 families brought home by the Hassler Expedition. This 

 number of the catalogue will contain five plates, besides fig- 

 ures printed in the text. 



The other alcoholic Echinoderms, with the exception of the 

 Crinoidse, have been placed in the gallery of the coral-room 

 by Mr. Birge, under the direction of Prof. McCrady. The 

 living pedunculated Crinoidse I have prepared for exhibition. 

 The fine specimens received from Gov. Rawson, of Barba- 

 does, form a marked feature of this set. 



The accessions to the collection of corals have not been 

 very large during the year ; a few interesting ones were 

 received from Mr. Arango, of Havana, and some fine speci- 

 mens of Floridian forms, new or imperfectly represented in 

 our collections, purchased from Dr. Palmer. 



The collection of Alcyonarians remains still in the hands of 

 Dr. Kolliker, of Wurtzburg, for determination.
