10 ANNUAL REPORT OF THE 
supervision of Professor Parker at the Laboratory of the U. 8. — 
Fisheries Bureau at Woods Hole. | 
Fifteen students pursued research problems in Zodlogy 20, 
three under the direction of Professor Castle, four under Profes- 
sor Parker, seven under Professor Mark, and one under Profes- 
sors Parker and Mark jointly. As already stated, in the case of 
six of the students working under the direction of Professors Par- 
ker and Castle, the laboratory requirements of the more formal : 
courses were met by devoting the laboratory time to the research : 
work of Zoédlogy 20. Mr. M. W. Blackman completed two papers, 
one of which he presented as a thesis for the Doctor’s degree, the 
other being on The Spermatogenesis of the Myriapods. IV. On | 
the Karyosphere and Nucleolus in the Spermatocytes of Scolo- — 
pendra subspinipes. | 
The work of several students is nearly ready for publication 
and that of others is well advanced. 
The degree of Doctor of Philosophy was conferred in June, 
1905, on Mr. Maulsby Willett Blackman, whose thesis was en- 
titled The Spermatogenesis of the Myriapods. III. The Sper- 
matogenesis of Scolopendra heros. 
Besides giving critical supervision to all the papers appearing 
as Contributions from the Zodlogical Laboratory and from the 
Bermuda Biological Station for Research, Professor Mark has
