SCIENCE. 



[N. S. Vol. XX. No. 519. 



Lamouroux, Meyen, Fewkes, Johnston, Busk 

 and Verrill, one each. These figures show 

 that although many able zoologists have 

 studied these animals, Nutting has done far 

 more to make known the American species 

 than any of his predecessors. 



In a few instances I find myself unable to 

 agree with Professor Nutting's nomenclature, 

 if I rightly understand the facts. Thus 

 Thuiaria dalli is a new name for Sertularia 

 cupressoides, Clark, 1876, because it is a 

 Thuiaria,, and conflicts with T. cupressoides, 

 Kirchenpauer, 1884. The rule here followed 

 is that recognized by many botanists, but is, 

 I think, losing ground, while it is not usually 

 considered valid in zoology. Surely it would 

 be more in accordance with zoological custom 

 (and, I think, common sense) to give priority 

 to the older specific name, no matter what 

 genus it was placed in, and consequently re- 

 name the species of Kirchenpauer, not that 

 of Clark. 



The natural history department of the Brit- 

 ish Museum is constantly referred to as the 

 ' South Kensington Museum,' which is not 

 exact, and would be understood by Londoners 

 to refer to a different institution.
