AUSTRALIAN HYDROMEDUS.'E. 17 



Y. Faniilia BLASTOPOLYPID.E. 



V. Lendenfeld, 1884. 



Forming colonies, with differentiated alimentary and mouthless generative 

 zooids. The latter are transformed polyps, polypostyles, and only in them the 

 sexual products are matured. 



I._ Sub-familia CORDYLOPHORIN^E. V. Lendenfeld, 1884. 



Alimentary zooids of the colony with scattered filiform tentacles, without 

 hydrotheca?. (65) II 601, (124) (131) 29. 



II. Sub-familia BIMERINJE. V. Lendenfeld. 1884. 

 Alimentary zooids, with one verticil of filiform tentacles, without hydrotheca?. 



III. Sub-familia CAMPANULARINJE. V. Lendenfeld, 1884.* 



Alimentary zooids, with one verticil of filiform tentacles enclosed in a 

 radially symmetrical hydrotheca, terminal on the branches. 



4. Genus MONOSKLERA. V. Lendenfeld. 



The stems consist of wedge-shaped internodes. The perisarc much thicker 

 on one side than the other ; the short hyclrocauli originate on the terminal 

 end of the internodes. 



6. Monosklera pusilla. V. Lendenfeld. (98) 

 South coast of Australia (Port Phillip). 



5. Genus LAOMEDEA. Lamouroux. 



The hydrocauli appear as long branches of a stem, and never arise from 

 the hydrorhiza ; the internodes are cylindrical, the hydrotheca! not, oper- 

 culate. 



7. Laomedea antipathies. Lamouroux. (15) 474, (83) 206 ; (85) 481, (93) 



403. 



Campanularia antipathes (9) 52. 



Sertularia antipathes (82) 138. 

 Australia. 



8. Loamedea Torresii. Busk. (17) 402, (93) 403. 



Campanularia Torresii (9) 52. 

 North coast of Australia (Torres Straits). 



9. Laomedea reptans. Lamouroux. (84) 14, (85) 483, (93) 403. 



Campanularia reptans (9) 53, (15) 473. 

 Sertularia reptans (82) 139. 

 North-west coast of Australia (Lewin's Land). 



10. Laomedea Lairii. Lamouroux. (83) 207, (84) 14, (85) 482, (93) 403. 



Campanularia Karsii (9) 53, (82) 153. 

 South coast of Australia (Port Phillip, Portland). 



*It is probable that this whole sub-familia must be united with the campanulinidse 

 and placed in the sub-ordo Hydromedusinse.
