Campaniclava cleodoræ (Gegenbaur). 
Syncoryne cleodorae Gegenbaur 1854, p. 11 —13. Taf. I, Fig. 3 & 4. 
Campaniclava cleodorae Allman 1864, p. 7. 
Hitherto only known from the Strait of Messina (Gegenbaur), 
where it was found on 4 A of all examined specimens of Cleodora 
cuspidata (= tricuspidata). 
It is found on the same species of pteropod in several local- 
ities in the Atlantic between Lat. 43° 10’ N. and 15° S., from 
the coast of Africa until Long. 34° 30 ’ W.; moreover on Lat. 10° 
S., Long. 104° E. in the Indian Ocean. 
Most of the colonies are fertile. They cover both sides of the 
shell without predilection for any side. 
Campaniclava clionis Vanhoffen. 
Vanhoffen 1910, p. 281. Fig. 7. 
Jaderholm 1920, p. 1. PI. 1, fig. 1. 
This peculiar species was found by the German South-Polar 
Expedition in the tropical Atlantic between Lat. 20° N. and 10° S. 
on Cleodora balantium ; recently Jaderholm (1920) has seen 
some colonies (in the Swedish State Museum) from Lat. 4° 38’ N., 
Long. 27° 15’ W., growing on the same species of pteropod. J å- 
derholm denies the presence of a gelatinous envelope around the 
short hydranth stem, as described by Vanhoffen. A perisarc is 
certainly present, but it is chitinous, not gelatinous; it surrounds 
the basal part of the polyp as a cylindrical tube, 2—3 times as 
long as broad. 
Every specimen of Cleodora balantium in the Zoological Mu¬ 
seum of Copenhagen is covered by Campaniclava clionis. Most of 
the specimens are from the Atlantic Ocean, between Lat. 21° 30’ 
N. and 19° 30’ S., from Africa as far out as Long. 36° W. — 
One specimen has been found at Lat. 33° S., Long. 58° E. in the 
Indian Ocean, and one in the Pacific near the Marquesas Islands.
