f S. episcopus.” Hartlaub (1905) says that he has no 
me o pis 
doubt of the identity of S. fusiformis with S. episcopus, neither does he ` 
doubt that Ridley had the same species before him. Ridley says, “ The 
growth is very strong, and the calicles large (:425 mm. in diameter 
at their middle), but they should be described as quadridentate, though 
the interior and exterior teeth are very short. The crest, described by 
Coughtrey on the upper side of the gonangium, is here, at any rate, à 
tube which opens in the side of the gonangium." In Hutton's specimens 
I find no trace of the two small teeth referred to by Ridley. The middle 
diameter of the hydrothecae ranges from about 0-33mm. to 0-4mm.

Of the numerous synonyms mentioned by me in the above-cited paper, 
Dynamena fasciculata Kirchenpauer and Sertularia crinis Allman are now 
associated, along with S. ramulosa Coughtrey, as a separate species, under · 
Kirchenpauer’s specific name. Dynamena pulchella D’Orbigny may be the 
same form.

Among Coughtrey's types from the Dunedin Museum is a specimen 
of his S. ramulosa, which I find to be identical with S. crinis Allman, and 
I have now no doubt that Kirehenpauer's D. fasciculata is also the same. 
Hitherto the latter has usually.been ranked as a synonym of 8. operculata, 
to which species Billard has also referred S. crimis.

it be admitted as specific or not) is very obvious. In Ж. o K
