Thirteen chapters are printed, leaving unfinished only the chap- 

 ters devoted to the zoological results, which await the final 

 reports of two or three special investigators. Professor Huxley 

 has kindly sent me for this Report drawings of the Spirula 

 dredged by the " Blake," which had been sent to him for use 

 while preparing his Report on the specimens of the same genus 

 collected by the " Challenger." 



The first part of the final Report of Mr. P. H. Carpenter on 

 the Crinoidea of the Challenger has been published.* This 

 includes also the Stalked Crinoids of the Blake which had 

 been sent to Sir Wyville Thomson, who intended to incorporate 

 them in his Report on the Challenger species. After his death, 

 the Challenger as well as the Blake collections were transferred 

 to Mr. Carpenter, who described the Blake material in connec- 

 tion with that of the Challenger, so that his Report is a com- 

 plete monograph of the recent Stalked Crinoids. The material 

 available for some of the species of Pentacrinus was very abun- 

 dant, and of this Mr. Carpenter has made admirable use. The 

 monograph includes not only a description of the various spe- 

 cies, but also a most thorough comparison of the Neocrinoids 

 with the Palseocrinoids. The species collected by the Blake 

 have supplied valuable material in the description of some of 

 the Stalked Crinoids included in the Report on the Challenger 

 Expedition Crinoidea. 



The collection of the Blake Myzostomida sent to Dr. L. von 

 Graff for study has been returned by him. The result of his 

 examination of the Blake species has been incorporated in the 

 final Report on the Challenger Myzostomida published in 1884. f 

 A Preliminary Report of the Blake species has already ap- 

 peared in the tenth volume of the Museum Bulletin. In ad- 

 dition to the twenty-eight species of the Blake expedition, 

 and the thirty-three of the Challenger, Dr. Graff's Report is 

 a complete monograph of this small group of animals, based 

 upon the collections of the principal Museums of Europe.
