‘104 Canon A. M. Norman—Wotes on the 
spines are replaced by short flattened plates; the ocecium is 
much larger than in the type, semiglobose, sparingly punc- 
tate, with a longitudinal keel ; in fertile zocecia the flattened 
plates just referred to do not nearly meet in the centre of 
the ocecium, but form two outspread wings overhanging the 
oral opening. 
Iam not sure that this should not be regarded as a species 
rather than a variety ; Mr. Waters gives the locality of the 
Jackson-Harmsworth specimen as off a glacier between Cape 
Flora and Cape Gertrude, Franz-Josef Land, in about 
30 fathoms. The specimens in my own collection are from 
Gray Hook, Spitsbergen, 90 fathoms (Smit), and off Hol- 
steinborg, Greenland, 57 fathoms (‘ Valorous, 1875). It 
would thus seem not only to be a high Arctic but also a 
deep-water form, since I also possess the ordinary typical 
form on shore-weed from both Greenland and Spitsbergen. 
J. E. Gray (Cat. Brit. Anim. B. M. pl. i., Centronine, 
p. 148) appears to suggest a generic name, Microstoma, for 
this species. This name can never, however, be employed, 
since it had previously three times been used for other 
genera. 
Genus RerrapEoneLta, Busk, 1884. 
In his ‘Challenger’ Report, Polyzoa, pl. i. 1884, Busk 
instituted a genus Reptadeonella, for the reception of the 
Adeonean form Lepralia violacea, Johnston (= Microporella 
violacea, Hincks). Three years later Macgillivray (Cat. 
Marine Polyzoa of Victoria, 1887, p. 110) instituted a genus 
Adeonellopsis with Adeonella distoma (=? Eschara cosci- 
nopora, Reuss) as its type; and this last genus J. W. 
Gregory (“British Palzogene Bryozoa,” Trans. Zool. Soc. 
vol. xiii. 1893) united with Reptadeonella, Busk. But 
Adeonellopsis has a distinct frontal area containing many 
fimbriated pores, and is a group for which Levinsen, doubt- 
less not remembering Macgillivray’s genus, has recently 
suggested another name, Lobopora (“ Studies on Bryozoa,” 
Vid. Medd. fra den Nat. Foren. 1 Kjobenhavyn, 1902, p. 24, 
separate copy). 
The dorsal view of the zocecium of Reptadeonella violacea 
is very pretty and of unusual interest, for there are not less 
than twenty-eight radii of alternating colour, darker or 
lighter, arranged all round the cell, which indicate many 
passages of communication between the zocecia. 
Of the other British species which Hincks placed in Micro- 
porella, Microporella Malusti, Audouin, has been made by 
Jullien the type of a genus Fenestrulina (Miss. Scient. Cap
