THE NAUTILUS. 



Voi. ix. JANUARY, 1896. No. 9 



TO CONCHOLOGISTS. 



We regret the necessity which compels us to start the new year 

 with an editorial of this nature ; but it is nothing new to hear that 

 the NAUTILUS must struggle for existence. This struggle has con- 

 tinued since the Jura, until now we have but a few species, three or 

 four in the Indo-Pacific and one in the United States. Do you in- 

 tend that the only recent NAUTILUS in North America shall be- 

 come extinct? We are willing to supply the care, but not the en- 

 tire environment. It needs feeding once a month in order to add 

 another septum. You are asked to assist in this important function 

 once a year ; and when you see a slip of paper which reads, " Inclosed! 

 please find $1.00," it means that it has come your turn to " chip in." 

 We hope that you will no longer neglect these little reminders. 

 They mean that your subscription is due. We cannot wait until the 

 end of the year we must have it in advance. 



Wishing you all a Happy New Year.

 when its hundreds of lakes and rivers are scientifically explored, 

 large and interesting collections will be made. The researches of
