There exist in the collection a few dried fragments of this species. 

 They were all obtained at Ojiya, on the island of Oshima or Vries 

 Island in the Sagami Sea.

Caberea climacina, Ortmann 1S90, Jap. Iïry., 22, pl. I, fig. 6. 



A large well-grown colony, which was obtained at Yodomi (78 

 fms.) in the Sagami Bay, seems to be referable to Ortmann's Caberea 

 climacina. The species closely resembles Caberea lata Busk, a species 

 which also occurs in the Sagami Sea. It was pointed out by Ortmann 

 that the former may be distinguished from the latter by the presence 

 of a transverse apertural spine in intermarginal zocecia and by the 

 total absence of lateral avicularia. We should note that, while the 

 latter negative character is a useful one, the former can not always 

 be relied upon for the differential purpose, since we find that in the 

 specimen now before us, the zocecia in the distal parts of the zoarium
