minute anatomy of Pentacrinus, for which the material collected 

 by the " Blake " is quite extensive. In addition to the Penta- 

 crinus material, our specimens of Holopus were also placed in 

 his hands. Mr. Carpenter is now preparing a preliminary report 

 on this part of the " Blake " collection. During the spring, 

 Professor S. I. Smith has completed his Report on the Crustacea 

 collected by the " Blake" off the Atlantic coast of the United States, 

 during the summer of 1880. We are under great obligations to 

 Professor Smith, not only for the masterly manner in which he has 

 accomplished his task, but also for his promptness in writing this 

 Report, and preparing the excellent plates which accompany his 

 Report. Professor Smith's Report was published in June, 1882.
