arise. Frequently tlie hnniclics end in Kliiiil stolons. The 

 hydrothecte are alternate and are borne at tlie <listal ends of the 

 internodes on short pedicels marked l)y four or five annuliition.s, 

 the base of the internode above tliat from which the podiu(tl 

 springs liearing si like nund)er of rings. The calycJes are sliort 

 and sul]triiingulMr, with a rather wide aperture and an almost 

 even, delicate rim. Thv whole colony is of delicate te.Kture, the 

 perisarc being leniarkably clear and liyaline. 



Gonosome not ])resent. 



The form described above seems to be a young stage of 

 0. dichotoma Ijinn. Its much smaller size, its lack of horn- 

 colour, its branches arising fiom the side of a pedicel, and the 

 shorter subtriangular shaiie of its hydiothecjc, are diflerences 

 insufficient to distinguish it specifically from the older form. 



Locality. On the carapace of a small crab found crawling on 

 the bottom of a lighter ; St. Vincent, Cape Verde Islands ; 30th

GoXOTHYRyEA GRACILIS (Sars 1851). 



A few small specimens of this beautiful species occ\ir growing 

 upon a fragment of calcareous material. The colonies are only 

 8 mm. in height. ;iud difler from those describeil anil figured by 

 Hincks (18(iH) in that the hydi(>tlieca> are somewhat less slender. 

 The reiuaining chnracters— the peculiar origin of the branches, 

 " stuck on, one would almost think, n.s an aftertliought, the gradual 

 tapering of the hy<lrothec;i towards its base, the number of the 

 long pointed teeth, tlie ringing beneath the hydrotlieca and at the 

 proximal end of the branches — agree with previous descriptions. 



Two long slender gonangia, with traces of a marginal collar as 

 in Hincks's figures, are jire.sent, one arising from the hydrorhiza, 

 the other from a peduncle.

Campanularia caliculata Ilincks 1803. 



Typical examples of this species, with crenated jicdicel, distal 

 spherical segment, and thick-walled, smooth-rinuned hydrothecie, 

 occur cree[)ing on .a seaweed. In our s]iecimens the peilicels 

 average 0"5 mm. in length and are marked by about 10 crenations. 



The gonangia are absent. 



Locatiti/. Porto Grande : creeping on seaweed in a shore-pool. 



Campan'ULARia rTYCiior VATin s Allman 1888. 



Numerous crowded, pedunculate hydrotlieca^, .■ind gonangia 

 springing from a creeping stolon have been found on a polyzo(m. 

 The specimens agree closely with Allman's description and figures, 

 especially characteristic being the delicate, freijuently collapsed, 

 distal portion of the hydrotlieca, which in our specimens bears 

 10 long teeth ; the stem with a few rings (generally two) beneath 

 the hvdiothi'ca and with several at the base ; the smooth
