I am led on to advert to his further suppositions regarding 

 the assumed developmental or transition states thereof draw^n 

 by him.i Beyond any question Greef's figures 26, 27, and 

 28 represent nothing else than Barker's Diplophrys Archeri,^ 

 and nearly equally certainly Greef s figure 29 represents my 

 own Cystophrijs ocidea? The nearly orbicular (Fig. 26) or 

 broadly elliptic (Figs. 27 and 28) figure of Diplophrys 

 is there, the large characteristic conspicuous oil-like, amber 

 coloured, refractive body, with the same little granular 

 bodies, are there, and the two pencils of delicate pseudopodia 

 emanating from opposite ends, but set slightly obliquely to 

 one another, are there, — all just as they occur in this very 

 marked little form, as it has presented itself in gatherings 

 made from the east, south, west, and centre of Ireland. But 

 although this wide distribution must be attributed to it, it is 

 always seemingly scanty, and rarely encountered ; this may 

 indeed be, in part, due to its great minuteness. Perhaps 

 Greef's otherwise excellent representation of this form would 

 have been improved if he had indicated that sometimes the 

 pseudopodia slightly subdivide dichotomously, and occasion- 

 ally show more or less of a changeable dilatation at the point 

 of ramification or along the length of a pseudopodium. I 

 myself have never seen anything like Greef's figure 25.

On a New Polyzoon, " Vtctorella pavida," from the 

 Victoria Docks. By Wm. S. Kent, F.Z.S., F.R.M.S. 

 of the Geological Department, British Museum. With 

 Plate IV. 



In November, 1868, I briefly referred, in the pages of 

 ' Science Gossip,' to a representative of the Ctenostoniatous 

 Polyzoa, taken by myself in the brackish waters of the Vic- 

 toria Docks. 



Though at the time possessing strong reasons for premis- 

 ing the species to be new to science, no name Avas conferred 

 upon it, and it was rather brought forward with the view of 

 attracting attention and possibly of recognition. 



Having been fortunate enough this last autumn to secure 

 fresh samples from the same locality, and feeling now con- 

 vinced that the form represents not only a new species, but 

 moreover, serves as the type of a new genus, and even family,
