 ohterfii, Hincks, in wliich he mentions tliat the sin<^le fo)'m of operculum 

 is present, and lemaiks tliat it may be i-egai-ded as a new species, I should 

 thiuk that this foi'm described may be refei)'able to X&diiifhiin'x.

Jn September of last yeai' the Kev. Dr. Tlios. Poi ter of Petershani, 

 N.S. Wales, ])i'esented two slides of Bryozoa to the Austialian Museum 

 represent inp^, as he contended, a new species of yitlhiplni'i-i mu . 



The specimens from which these slides weie j)iepared were dredged 

 iu Bass Strait by jMr. .1. \Vilson of North Fitzroy, Vicfoiia, a gentleman 

 to whom microscopical science owes much, aiul it is with pleasure that I 

 associate his name with this new species. 



The genus L'nUii iihifrin m was created by Maplestone'' to accommodate 

 liis new foini from the Gilbert Jslands. He lemarks on the differences 

 between this and Jiijiloerin m, but with Kii-kpatrick*' he does not allot liis 

 genus to a family. I have not seen lUfilnrriioii, but my examination of tlie 

 species about to be desci'ibed, and the paratype of ./'. ijilliertoii,<itt, shows 

 that VoUiiphii'i-iinn- should be accommodated in the family Onchoporidff' 

 according to Levinsen's' diagnosis : 



"The slightly calcified ::i>irria, the frontal surface of which is covei'ed 

 by a closely adliering (chitinous r*) membrane, are generally provided with
