CouGHTREY.— xVb^es on the New Zealand Hydroidese. 291 



flexuously zig-zag, simple or dichotomously branclied, incrassated below the 

 joints and ringed above them. Arising from a delicate tubular hydrorhiza 

 that runs in parallel rows chiefly on older and dead fronds of larger seaweeds. 

 Hydrothecse on ringed pedicels, rings vary from four to eight in number, 

 aperture entire. 



Gonangia, various forms, generally urceolate, some with pure tubular crown 

 and erect aperture, others with an everted lip, others with no crown at all, 

 and these are campanulate ; gonangia pedicellate, pedicels of two to four rings. 



Habitat. — Eronds of seaweed. Yery widely distributed. 



Captain Hutton was the first to discover and determine this species in 

 New Zealand, and incorporated with the above description are some notes he 

 lent me. Figs. 42 — 44. 



Genus Campanularia, Lamarck. 

 Hydrosoma branched or simple, pedicels long. Arising irregularly or in 

 verticils. Gonophores sessile. 



Campanularia Integra (?), Hutton. 



Macgillivray, Ann. and Mag. N. H., IX., 465 ; Johnst., I. c, p. 109. 



" Hydrocaulis a single creeping filiform tube j hydrothecse on long slender 

 twisted pedicels j campaniform, with an entire rim. Gonangia large, sessile, 

 campanulate, slightly constricted below the rim, which is entire. 



" On Fuci, Wellington Harbour." 



I have not been able to get a fresh specimen of this species, and although 

 Captain Hutton gave me some dried specimens I prefer giving a description 

 he gave me of it, which had been taken whilst the object was fresh. 



Of this I am certain, however, that the species figured in fig. 45 (which is 

 taken from a fresh specimen got at Tairoa Head) is not Campanularia 

 Integra, Johnston. 



I defer my notes on this species until I have had further opportunities of 

 studying it. 



Campanularia bilabiata, sp. nov. 



Hydrophyton creeping and gelatinous. Trophosomic and gonosomic 

 elements distinct, former stalked, latter sub-sessile. 



Hydrocaulis 0*5 inch in length. Erect, simple, one-celled, contracted at 

 hydrorhiza, only one bead-like joint at proximal end of hydrotheca. Caenosarc 

 tumid at each end of this bead. 



Hydrotheca at an oblique angle to stalk, digitaliformly campanulate ; lip 

 sinuously bilabiate. 



Gonangia almost alternate with nutritive buds. Two forms long and 

 short. General form urceolate, but endoderm has a marked campanulate
