Actiniaria from New Zealand and its Subantarctic Islands.

Oskar Carlgren, Lund.

Though several Actiniaria from New Zealand and its sub¬ 
antarctic islands have been described by various authors, our know- 
ledge of the Actinian fauna of these islands is rather imperfect. 
Almost all species, described before, are littoral forms and so it is 
also with the species in the collection of Mortensen. The older 
descriptions of the species, as those byFarquhar and especially 
Hutton, are for a great part rather incomplete and based only on 
outer characters. In the recent descriptions by Stuckey, Kirk 
and Stuckey, Stuckey and Walton, Stephenson and 
Clubb also the anatomy of the forms is treated. Especially 
Stuckey has increased our knowledge of the Actinian fauna 
New Zealand’s. In his paper (1908) is given a review of the forms, 
known to 1908. Unfortunately the preservation of Stuckey’s spec- 
imens was often far from good — he has namely used perchloride 
of mercury as fixation means, which, according to my experience, 
only exceptionally gives good results — wherefore his anatomical 
descriptions are often incomplete and sometimes wrong. For this 
reason it is often difficult to identify his species as also those of 
which only the exterior is described. After the publication of Stu- 
ckey’s paper 1908 some contributions to our knowledge of the 
Actinian fauna in these districts are given by Stuckey and Wal¬ 
ton, Clubb and Stephenson (compare the list of literature). 
I beg to express my best thanks to Dr. Mortensen for giv- 
ing me the opportunity to study this collection.
