Dr. Billard'^ 1ms used tlie specific name "■ ivtervit^Jin'''' for a 

 sj)ecies of HdlicoiiKirin. On account of the s])ecific name 

 " iitteniiedia " being tlius preoccupied, Bale, in an Addendum 

 to tlie Keport on tlie "Kndeavour" Hydroida, reduces liis 

 species to varietal rank. He wiites: — "This species (I.p.JI. 

 I'literDieiUa, Bale), howevei-, was a veiT doubtful one, and in 

 preference to establishing another specific name, I pio])ose to 

 retain the name iviermedin, but treating the Hydroid as a 

 variety of Jl. fnrcttfn, until more is known of the affinities of 

 the two forms." The Siboga Re])ort is dated 1918. Bale's 

 paper was published on tlie 2nd January, 1914. 



For comparison I append the dimensions of 7/. furrnhi 

 deduced from Bale's figuies,^ and the measurements given by 

 Ritchie^^ for the specimens of H. furcdfa obtained by the 

 '• Thetis."
