The size and shape of the zocecia, as well as the position of 

 the operculum in Jullien's Carbasea ramosa, is identically tiie 

 same as in C. ovoidea, Busk, collected by tlie ' Challenger,' and the 

 thicker wall on the front near the proximal end occurs in the 

 Cape Horn specimens, as described by Busk, when he says 

 " membranous aperture occupying the upper two-thirds of the 

 front." In the Cape Horn speciraena there are 15-16 tentacles 

 and 4-6 lateral rosette-plates, and numerous distal pores. I 

 previously gave two lateral rosette-plates for C. ovoidea, Busk, 

 but on examining more satisfactory material it seems that I had 

 taken the half of the wall for the complete wall. 



Although the zoarial shape is not identical in C. ovoidea, Busk, 

 and Flustra ramosa, JulL, the differences are not very important, 

 and there is no doubt as to their identity.

This is apparently not uncommon, and grows on Itetepora, 

 Aspidostoma, &c., but no ovicells are found in any of the speci- 

 mens from Cape Horn. There are large pores on the front of 

 the zooecium. The opening of tbe avicularium is characteristic 

 (fig. 15), there being a narrow opening in the rounded portion, 

 which becomes wider in the part under the mandible.
