intermediate pair. The moutli is nearly horizontal, and on each 

 side of it the cell is produced into a thick, conical, hollow process. 

 The small round ovicells are situated above and behind the 

 aperture. In some specimens the ovicells are smooth, in others 

 they are more or less distinctly marked like a miuiatm-e Clam-shell, 

 as descriljed and figured b}^ Thomson. It is quite possible that 

 there may be more than one species, but the specimens in my 

 possession are not sufficiently perfect to enable me to say with 

 certainty.

Plate 46. — Fig. 7, specimen, natural size. Fig. la, portion, magnified ; the lower part has 

 been a little twisted. Fig. lb, showing two ovicells. The specimen was not sufficiently perfect

The descriptions and specimens of the Polyzoa on this plate have 

 been contrilmted to this work and the National Museum by my
