With plate 11-12. 
While working at the Marine Biological Laboratory at Woods 
Holl, Mass., July and Aug. 1901, I came across Alcippe.” The season 
was then already advanced and I collected as much material as 
possible to work it up later. It appeared that for about fifty years 
almost nothing had been done on this animal except that AuRIvILLIUS 
in his “Studien iiber Cirripedien” had given some valuable contri- 
butions esp. to the anatomy of the male. The original papers by 
Hancock (1849) and Darwin (1851), though excellent in themselves, 
on account of their early dates of publication made a reexamination 
with modern methods desirable. For over a year, however, I found 
myself unable to take up this matter. I had planned a somewhat 
full and detailed study beginning with the anatomy, taking the 
embryology next and go on if possible. Last October when I was 
almost about to finish the first part of my studies, I received 
BERNDTS paper in the Ztschr. f. wiss. Zool. published in June 1903. 
The publication of his careful researches renders most of what I 
had to offer superfluous, for I see no object in duplicating anatomical 
statements. 
On the other hand, I feel that I have given too much time to
