processes at the atrial end are not adequately recognized in any 
of the published figures. This is due in part to the fact that 
they are very short in the younger zooids, and in part to their 
being, in adult preserved specimens, either broken or worn off, 
I have examined specimens of about 1.5 em. in length from the 
mid-Pacific, practically the region in which Chamisso obtained 
his, and find the processes short though distinctly indicated, 
essentially as they are shown in Traustedt’s figs. 7 and 8, Pl. I. 
Finally, Traustedt figures an arrangement and anatomosing of 
the seventh and eighth muscle bands of the solitary generation, 
somewhat different from anything I have seen, but the point is 
a trivial one, even if his representations are entirely correct. 
The species has been obtained at Santa Catalina Island and 
off San Diego during the months of March, June, July, and 
August. It was particularly abundant during March, 1904, in 
the last named locality, and was reproducing actively, both sex- 
ually and asexually.
