The specimens, which are common in Lifu, seem to be intermediate between 

 Canda retiformis, Pourtalfes and Canda arachnoides, Lamouroux. The foiiiix is \w\\ 

 developed, its lamina being as long as the aperture, rounded at the base, produced 

 and pointed above. It differs in this respect from the specimen of Canda, retiformis 

 (from Victoria Bank, Brazil) in the British Museum, in which the lamina is small 

 and equally developed on both sides of the stalk. Smitt however (Flor. Bryozoa, I. 

 PL v., fig. 44) figures the fornix in this species as varying considerably' in form. 



On each side of the upper margin of the aperture there is a spine, the two 

 being equally developed.
