peas, with litttle protuberances on them, semitransparent, horn 

 coloured, or rather of a greenish-horn colour, having quite the 

 appearance of small gum capsules, and were clustered on the tops 

 of the plant like inverted bunches of grapes. — Ibid. 



On a New Species of Plumatella, and on the Occurrence of 

 Fredericella sultana^ near Newcastle^ and of Lophopus crystallinus^ 

 in Northumberland. — In the autumn of 1857, I found in ponds 

 and brooks near Whitburn, Cleadon, Roker, Southwick, and 

 Hylton, an undescribed species of Flu?natella, for which I pro- 

 pose the name oi proxima. It was very abundant on the under 

 surface of the leaves of the common pond weed, and on sub- 

 merged stems and branches. In general habit it closely resem- 

 bles P. repens^ but is distinguished from that species by having 

 the coenoecium keeled, and by having attached as well as free 

 statoblasts. I hope soon to be able to lay before the Club a 

 full description of P. proxhna., with illustrative figures. Within 

 the last few weeks I have also procured this species from two 

 localities in Northumberland — namely, from a pond in the 

 grounds of Mr. Robt. Dees, at Wallsend, and from a pond near 

 Fenham. About the same time I took a single specimen of 

 Fredericella sultana in a large pool in the Ouseburn, a little 

 below Freeman's Water Mill. This is the second recorded 

 locality within our district for this fine species of polyzoa, the 

 other being the Northumberland lakes. I may here observe that 

 one of the specific identifications in my paper, " On the Anatomy 

 of the Fresh- Water Bryozoa," published in the 1st vol. of the 

 "Transactions" of the Club, is erroneous. It is there remarked, 

 that " amongst the known species was a fragment of Alcyoiiella, 

 most probably A. stagnorwn; but its character could not be 

 determined on account of the imperfection of the specimen." It 

 now appears that the fragment alluded to was an injured indi- 

 vidual of Lophopus crystallinus. The drawings made of it at 

 the time fully establish this, as they agree in every essential 

 character with the figures of this species given in Dr. Allman's 

 excellent " Monograph of the Fresh-Water Polyzoa ; " but 

 being influenced by the then generally adopted opinion, that this
