448 Rev. Canon Norman — A Month on 



side, which we none of us recognized as sucli, its character 

 being so entirely different from any previously known 

 form of that organ. Alder represented on fig. 6 certain 

 organs on the back of these zooecia, which apparently I could 

 not see, as I did not describe them. These, I take it, 

 were the central avicularia appearing through by trans- 

 mitted light, and their position rather altered by refraction. 

 Lastly, the very small imperfect lateral avicularia, which I 

 had mistaken for broken spines, Hincks rightly recognized 

 as avicularia.

I had the satisfaction of procuring several perfect examples 

 of this rare and remarkable Polyzoon in about 70 fathoms at 

 Rodberg. I was previously indebted to Dr. Dcinielsseu for 

 the head of a specimen of the species he had described, but 

 had not seen the perfect form until I went to Trondhjem. 



Other known localities for this species are Stotholmen 

 Fiord, Nordland, 80 fathoms [Danielssen)^ Kors Fiord, en- 

 trance to Bergen Fiord, 150-200 fathoms {Danielssen and 

 Koren), 300 fathoms, no locality [M. Sars). 



Among the Polyzoa of the ' Challenger ' Expedition two 

 species attracted great attention — Cephalodiscus dodecalophas, 

 M'lntosh, and one whichWyville-Thomson described as Naresia 

 cyathus, and which Busk afterwards found to be so closely allied 

 to Kinekoskias Smitti that he had some doubt whether it was 

 distinct or not. It will be well therefore to clear up this 

 matter, and I am indebted to the British Museum for a small 

 fragment of the type of Thomson's species which enables me 

 to make direct comparison. I shall take it for granted that 

 the descriptions already given of the two species have been 

 consulted, and shall only draw attention to points of differ- 

 ence or corrections of errors.

The total height is 4^ inches ; of this the first three quarters 

 of an inch is composed of the dense mass of fine rootlets which 

 are distributed through the mud and hold the zoarium in its 

 position ; the next three inches are the stem, which is about
