Ascidiæ from the Auckland and Campbell Islands. 
(Holosomatous forms). 
By 
Prosper Bovie n. 
(With Plate IV). 
The material of Ascidians collected by Dr. Th. Mortensen at 
the Auckland and Campbell Islands in Nov.—Dec. 1914 contains 
in all only 7 species (Didemnids excepted). Considering the faet 
that hitherto only one single species, Corella eumyota , had been 
reported from those islands, namely by Herd man, in his report on 
the Tunicata of the Nat. Antarct. Exp. 1910, while not a single 
species had been found (or at least mentioned) by the New Zea¬ 
land Expedition or by the Transit of Venus Exp. (Filhol), this 
present collection nevertheless represents a very noteworthy addit¬ 
ion to our knowledge of the marine fauna of those remote islands. 
The species collected are the following: 
Molgula amokurae n. sp. 
Halocynthia carnleyensis n. sp. 
Cnemidocarpa aucklandica n. sp. 
Polyzoa reticulata Herdm. 
Alloeocarpa affinis n. sp. 
Botryllus sp. 
Corella eumyota Traust. 
(Besides these, some colonies of Didemnidae are present.) 
Only two of the above mentioned species I have been able to 
refer with certainty to species previously described; the other species 
I have thought it necessary to describe as new, in spite of the faet 
that they are more or less closely related to species previously
