PROCEEDINGS OF THE SOCIETY. 797 



mention would have been made of the subject at all from the Chair 

 had it not been necessary for the Council to find immediately a gentle- 

 man to assist Dr. Hebb in his secretarial duties, and they felt grateful 

 to Mr. F. S. Scales for so readily responding to their request and coming 

 to their rescue, anyhow, till the next election of officers. This, then, 

 Gentlemen, the Chairman added, explains why we have the pleasure of 

 seeing Mr. Scales in the chair formerly occupied by Mr. Gordon. 



Mr. F. Chapman's paper, "On the Microscopical Structure of an 

 Inocerainous Limestone in the Queensland Cretaceous Rocks," was read by 

 Dr. Hebb, and illustrated by the plates to which reference had been made. 



The thanks of the Society were unanimously voted to Mr. Chapman 

 for his paper. 



Mr. C. F. Rousselet called attention to a specimen of the rare 

 spherical Rotifer, Trochosphsera sequatorialis, shown in the room that 

 evening, which had never been exhibited in this country or anywhere 

 else before. It came from Brisbane, Queensland, where it was first 

 found in 1889 by Surgeon Gunson Thorpe, but had disappeared for a 

 long time. This species, which was originally discovered about fifty 

 years ago in the Philippine Islands by Professor Semper, is of peculiar 

 interest, as it closely resembles in outward form the Trochosphsera larva? 

 of the marine worm Polygordius, and to this resemblance has been in 

 great part due the theory that the Rotifera are derived from worms. 

 The discovery of Pedalion has later thrown doubt on this derivation. 



Mr. Wesche said that when he visited Brisbane Mr. Rousselet asked 

 him to look up the particular pond where this Rotifer had been found, 

 and if possible to i >r< >cure some specimens. He was informed, however, 

 that a tidal wave had washed out the pond and destroyed all that had 

 been in it. 



Mr. Wesche thought that this resemblance to a larval w T orm bore 

 out Huxley's idea that the Rotifera were permanent forms of larvae. 



The Chairman said they must not only thank Mr. Rousselet for his 

 communication and exhibit, but must congratulate him upon obtaining 

 so rare a specimen. 



It was announced that the " Biological and Bacteriological " Section 

 would meet on November 3, at 7 for 7 . 30 p.m. ; also that the " Brass 

 and Glass " Section would meet on the fourth Wednesday in the month 

 at the same hour.
