 New York and Brooklyn more intelligible, and to aid, even if it be

 these institutions to perform. 



It gives the author sincere pleasure to express his gratitude to 

 the authorities of the Museum of the Brooklyn Institute of Arts and 

 Sciences in alloAving him to take photographs of specimens upon 

 exhibition within the Museum. 



Of the 119 figures; 111 are derived from photographs of living 

 or dead specimens, while eight are taken from hitherto unpublished 

 illustrations. Of the illustrations ; three representing a coral reef 

 of the Bahamas, the giant squid, and the American octopus are from 

 paintings by Herbert B. Judy, Esq. The originals are on exhibi- 

 tion at the Museum of the Brooklyn Institute of Arts and Sciences. 

 Five illustrations are from drawings by the author. Of the 111 

 photographs of animals ; one, that of Sagartia leucolena was pre- 

 sented by Mr. William F. Patterson, while the remainder were
