Thirteen chapters are printed, leaving unfinished only the chap- 
ters devoted to the zodlogical 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 Palocrinoids. 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 1884.7 
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.
