Zoologt/.'] NATUHAL HISTORY OP VICTORIA. [_Polyzoa. 



QuccnscHff. 



From C. plogiosfoma., to which it is closely allied, it may be 

 distinguished by the following characters : — The mouth is straight, 

 or nearly so ; the anterior forauiina, although arranged in the same 

 manner, are of smaller size ; there are none of the peculiar enor- 

 mous spoon-shaped avicularia; the back also is smooth. The large 

 lateral process, with its tolerably large avicularium, usually exists 

 only on one side of the cell. 



Mr. Goldstein has furnished me with some notes and sketches of 

 the animal of C. mars>arifacm observed by himself and Mr. ]\Iaple- 

 stone, of Portland, but Avishes to confirm the observations before 

 publication. The descriptions are from my friend Mr. MacGillivray. 

 The two last species are given here to complete the series of species 

 of CatcnlrcUa in the collection from our shores, although there was 

 not room on the plate to figure them. I hope to figm-e them on 

 another plate hereafter with some other additions.
