 the roe is also edible. 



Our four specimens, the largest being about 

 eighteen inches in length, were obtained by ex- 

 change with the Detroit Aquarium. 



A MUSEUM POSTER. 



LAST spring the public museums of New 

 York united in the production of a large 

 poster containing information respecting 

 our City museums, two of which are under the 

 control of the Zoological Society. As the ac- 

 companying reproduction shows, it states the lo- 

 cation, hours of admission, character of exhibits 

 and how to reach each museum. The six illus- 

 trations and the map are in colors. 



This poster, framed, has already been located 

 in universities, high schools, libraries, Y. M. C. 

 A. buildings and in several railway and ferry 

 houses. It is to be located in other public places 

 with a view to bringing the public museums of 

 the City closer to the people and to the educa- 

 tional institutions, generally. 



SPAWNING OF THE WHELK. 



AS an illustration of the opportunities which

 tory observations, attention is called to the

 the spawning process of the channelled whelk, 

 (Fulirnr canaliculata). 



The empty shell of this large mollusk is a 

 common object around the shores of Long 

 Island, but the living animal is seldom seen un- 

 less special search is made for it. Its range is 

 from Massachusetts to Florida. Specimens are 

 often brought from Gravesend Bay, north of 

 Coney Island, to the Aquarium, where they may 

 be seen in the exhibition tanks throughout the 

 vcar. The dry egg-cases of the animal all con- 

 nected by a ligamentous cord, arc frequently 

 found along the beaches, but comparatively few 

 persons know what they are. Although natural- 

 ists have described the manner in which the eggs, 

 or rather the egg cases, are cast off under natural 

 conditions, very few have had the op])ortunity 

 of seeing the process in an aquarium and of 

 recording the tinie actually required for its com-
