4. ADDITIONS TO THE SPECIES SINCE FARQUHAR's List. 
endorf's paper of 1897 are included six species said to be new 
to New Zealand. They are as follows :— 
Tubiclava fruticosa Allman. (The identification with Allman’s 
species is doubtful, and the form does not appear different from 
a Farquhar.) 
ѕ n. Sp. 
Calycella parkeri n. sp, (This is not at all like a Calyodila, but is 
a typical Gonothyraea, very probably G. hyalina Hincks.— Vide 
G. Parkeri.) 
Hypanthea asymmetrica n. sp. (The same as Eucopella campanularia 
v. Lendenfeld, now referred to Silicularia.) 
Aglaophenia filicula Allman. (Identification very doubtful.) 
Hartlaub, ud - paper of 1901, adds the following :—-

Obugiitiey. See igi nod crenata. 
Thyroscyphus tridentatus (Bale). (= T. simplex (Lamouroux).) 
Sertularella tenella (Alder). (One of the чека included by Meter

Not 8. tenella ? 
Sertularella solidula Bale. (Not S. solidula; see S. crassiuscula.) 
Sertularella fusiformis Hincks var. nana (Is S. simplex Hutton.) 
In a paper in Trans. N.Z. Inst., vol. 47, p. 146, 1915, Professor 
H. B. Kirk describes a new genus and spec ecies, Ascidioc lava a parasitica 
The hydroids which in the present paper are recorded as new to ‘the 
New Zealand region are the following :— 
Syncoryne sp. Bale. Sertularella edentula n. sp. 
Syncoryne eximia Allman. се setacea (Ellis) var. opima 
Obelia nodosa n. sp. n. va 
Obelia coughtreyi n. sp. Plumularia wattsi Bale. 
Campanulina humilis n. sp. us ona n. sp 
Thwaria farquhari n. sp. Aglaophenia plumosa Bale. j 
Sertularella columnaria n Thecocarpus chiltoni n. sp. 
Sertularella crassiuscula n. Halicornaria rostrata n. sp. 
The references prefixed x the various pae prom are not exhaustive. 
In a number of cases, where no change has occurr the nomenclature, 
I have commenced with a reference to Farquhar's liat where the earlier 
ооуу will be found. In other cases I have referred for the synonymy 
more recent UN where they are easily procurable, like the 
T « Endeavour ” Reports,
