30 ON BRISBANE ROTIFERA, 
2. Salpina ——. Nearest to Salpina eustala, but differs 
from it in that the lumbar spine is longer than the alvine 
spine, which is the reverse in S. eustala. Rare. 
VII. Family ‘‘ Euchlanide.” 
1. Euchlaais triquetra. Rare. 
VIII. Family “ Pterodinadz.” 
1. Pterodina patina. Rare. 
By bringing this subject before the notice of this Society, I wish 
to draw attention to a fact of the greatest interest, z.e., the cosmo- 
politan distribution of these organisms.* The forms which I 
have enumerated are all found in the fresh waters of England. 
Nevertheless I feel sure that there are many species of the 
Rotifera which are at present unknown, and that Australia will 
furnish a rich and hitherto untouched field for the investigation of 
this subject. In conclusion, allow me to express a hope that 
before long the Colony of Queensland, like one or twe of its sister 
colonies, will possess its Microscopical Society, the existence of 
which would go far to further the interests of the science at home 
and abroad.t

* Mr. Whitelegge informs me that several new species, as for example, 
Melicerta conifera, Copeus caudatus, and Copeus spicatus were discovered 
at almost opposite sides of the globe (i.e,, in England and in New South 
Wales) at the same time. 
+ The preservation of Rotifers is rather difficult. Mr. Whitelegge has 
succeeded in preserving them as follows :—‘‘ Mix equal parts of chloroform 
and spirit; put 2 drops in a test tube and allow it to act for a few seconds, 
afterwards adding spirit drop by drop till the Rotifers are fixed. Others 
appear to succeeded with cocoaine.” I have been using a 2 per cent. sol. 
of osmic acid with tolerably successful results.
