MATERIAL EXAMINED. — Loyalty Islands. MUSOR- STOM 6 , stn CP 464, 21°02.30’S, 167°31.60’E, 430 m, 21.II.1989, one damaged colony as epibiontic on Plumulariidae ; no gonothecae ( MNHN).

DISTRIBUTION. — Kirchenpaueria bonnevieae is widely distributed in the Atlantic and Indian Oceans, with some isolated records in the West Pacific ( Ansín Agís et al. 2001). In the Atlantic it has been recorded from many localities, from Norway (Trondhjem Fjord) to South Africa, and also from one locality in the Mediterranean Sea (Alborán Sea). In the Indian Ocean it has reported from South Africa, Mozambique, Zanzibar, Tanzania, Oman and Kerguelen. In the Pacific it is only known from Sagami Bay and New Zealand.Bathymetric distribution between 11 and 1280 m. Our material comes from a single station in the Loyalty Islands, at 430 m.

VARIABILITY

Many internodes with two mesial inferior nematothecae.

Height of colony (in mm) 22

Stem internode, length 640-3070

Length free part adcauline wall 35-60

Mesial nematotheca, length 50-60

Diameter at rim 40-60

REMARKS

Material studied from the Loyalty Islands is characterized by several internodes with two mesial inferior nematothecae. Despite this variation, the morphology of the colony is identical with those of K. bonnevieae .
