Dr. S. Kneeland, Jr., made a communication on the 

 habits of the Menobranchus, two specimens of which 

 had been in his possession for nearly two years, and 

 which are still apparently in good health. 



These specimens, which he obtained in Portage Lake, which 

 flows into Lake Superior, have not perceptibly increased in size 

 during this period. During the last winter they did not change 

 their skin ; this was changed the year before during the month of 

 December, coming away in shreds. In addition to what is men- 

 tioned on pages 152, 218, and 280, of Vol. 6, of the Proceedings 

 of the Society, the following facts have been observed. 



They do not like the sunlight ; however sluggish they may be, 

 they become agitated when placed in the sun, and at once attempt 

 to get out of it, retiring, if possible, to a part of the vessel in th« 

 shade.
