nearly or quite uniform in diameter to end, exactly as in Allman 
A. laza. The first pair of lateral teeth of hydrotheca are very broad 
and obtuse, and in profile they usually overlap anterior tooth, which has

are as shown by Allman, Lateral sarcothecae become much larger 
towards ends of hydrocladia (a character seen even more conspicuously 
in some forms of A. divaricata). Hydrothecae, like the whole polypary, 
are smaller and more delicate than those of A. divaricata and its varieties. 
his is especially the case with Kermadec specimens. Allman, like 
Jaderholm, gives no indication of erect crest on anterior tooth, which is 
well developed ; and Jaderholm shows the first pair of lateral teeth as 
narrow and pointed in side view, and widely separated from median one— 
in other respects his figure agrees well with my specimens.
