NOTICE. 



IN the year 1888 my predecessor, Dr. E. P. Ramsay, acting 

 on instructions from the Trustees of the Australian Museum, 

 forwarded the collection of Tunicata descrihed in the present 

 catalogue to Prof. W. A. Herdman, of Liverpool. In 1893, 

 however, just as the work was about to he sent to press, 

 circumstances of an official character, beyond the Trustees' 

 control, temporarily put a stop to its publication. It now 

 affords me much pleasure to say that in 1897 it was again 

 possible to contemplate the publication of the catalogue, 

 which was therefore at once completed, and is now issued 

 as one of the Museum Series. 



At the time the specimens were forwarded to Prof. Herdman 

 they formed a complete collection of the Tnnicata of the 

 New South Wales coast, as then known to us, and very few 

 additional forms have since come to hand. It is, however, 

 unquestionable that by systematic collecting which, unfor- 

 tunately, the Australian Museum is not at present in a 

 position to carry out the list might be very much enlarged. 



In addition to the Museum material, Prof. Herdman has 

 incorporated certain forms known to him, but at present not 

 represented in the former. A preliminary list was published 

 by Prof. Herdman in "Annals and Magazine of Natural 

 History," 7th series, vol. I., p. 443, in June, 1898.
