stem. Immediately below the spiral a wide oi)enin^' (IM. \ 1. 

 fig. 3,1/) leads into the tubular jiassagi- by whieli tlie (.'lubryus 

 make their escape, wliieh bonds upwards within tiic cai)sule 

 and terminates in a cireular oritiee near the top (PI. VI. iig.3,x). 

 The gonophores, which are numerous, form an elongated mass 

 nearly filling the cavity of the gonotheea ; the ova seem to be 

 discharged successively from the nppennost, and to pass into 

 the planule stage while lying free in the capsule. The em- 

 bryos, when mature, make their way by means of their cilia 

 towards the npper extremity, enter the tubular passage at x, 

 and make their escape into the water at // (PI. YI. fig. 5). 



If the external tubular orifice of an ordinary Campanularian 

 capsule were reversed, and drawn within the cavity, so as to 

 project into it instead of projecting from the summit into the 

 water, and were then bent round and upwards on one side, 

 we should have the very form which is characteristic of this 

 species. A slight modification of structure has resulted in the 

 production of a most exquisite shape. 



Ilab. Salcombe Bay, on stones ifcc. ; not uncommon. 



Genus LovENELLA, Hincks. 

 L. clausa, Lovdn. 



On small stones, di-edged off the Oar Stone, at the entrance 

 to Torbay, in about 10 fathoms ; Salcombe Bay, abundant, 

 especially on shells of Tarritella communis. 



\Vlien the genus Lovenella was first characterized, I was 

 only acquainted with the ti-ophosome ; but in ^lay I procm'cd 

 specimens at Salcombe with gonotheea?, and was able to study 

 the gonozooid, and so complete the diagnosis. The reproduc- 

 tive zooid is medusiform, and bears a general resemblance to 

 that of Clytia Johistoni] but there are important differences 

 in the number and position of the marginal bodies and in the 

 tentacles. The following should be added to the generic cha- 

 racter as given in my ' llistory of British Hydroid Zoophytes,' 

 vol. i. p. 177 : —
