population of the globe; and to exercise their just sway in 

 scenes unpolluted by the many sad acts of human selfishness, 

 perfidy, despotical dominion, and carnage of the older por-

This colony of Victoria will be added to the list of unex- 

 ampled strides made in the last half century, and will yet be 

 spoken of in connection with steam-power, gas, a hundred- 

 fold increased manufacturing capabilities, electricity, photo- 

 graphy, and the many other additions to human advantages, 

 which are the distinguishing characteristics of our age and 

 nation. 



Art. XV. — Notes on the Cheilostomatous Polyzoa of Vic- 

 toria and other parts of Australia. By P. H. Mac- 

 Gillivray, A.M., M.R.C.S. 



[With a Plate.] 

 [Read before the Institute Oct. 26th, 1859.] 



Having had opportunities of examining a considerable num- 

 ber of Polyzoa from our own colony and several other parts of 

 Australia, I am induced to present to the Institute a complete 

 catalogue of the species of the Cheilostomatous sub-order 

 which have hitherto come under my observation. A large 

 proportion of them have already been described, but several 

 are new to science, and some previously known are now 

 for the first time recorded as Australian. I would par- 

 ticularly call the attention of any members who may study 

 this class to the fact that little is known of the structure of 

 the animals in the genera most characteristic of the southern 

 seas, and that the details of the anatomy of Catenicella espe- 

 cially would be of high scientific interest. I would also 

 recommend a careful examination of the MembraniporidaB, 

 which, although extremely abundant in other parts of the 

 world, seem to have almost escaped the notice of naturalists 

 in Australia, and of which I believe that a diligent search 

 would add many species to our fauna. In other genera also 

 a large accession to the already extensive list may be confi- 

 dently anticipated. 



The arrangement adopted is that given by Mr. Busk, in 

 his admirable British Museum Catalogue. 



I would here beg to express my thanks to those friends 

 who have kindly aided me by the contribution of specimens.
