The minutes of the last meeting were read and confirmed.

 respective donors. Among the donations was a series of prepara-

 requested by the Secretaries to report upon. 



To the President of the Eoyal Microscopical Society, London. 



137, Castlereagh Street, Sydney, Juhj 12, 1871. 



Sir, — By this mail I have sent to your Society twenty-four micro- 

 specimens prepared by me, in order that your Society may identify 

 and name the several entozoa hereby forwarded. 



Our Agricultiu-al Society have also sent you a copy of their journal, 

 in which you will see that I have given a description of the lung, 

 intestinal, and tape worm infecting our sheep, with illustrations of 

 the principal characteristic features of said worms. In looking over 

 the illustrations, please make a note of x 35 instead of x 25 (an inch 

 objective being used with the camera lucida). 



At the present time our cattle, sheep, and pigs, are all infested 

 with parasites, and within the last few days another new worm has 

 been sent me to investigate, its habitat being in the fat (or flip) sur- 

 rounding the kidney of the pig. I have sent you six diiferent pre- 

 parations : a male and female ; caudal extremity of the male, showing 

 cup-like bursa with a double (V-shaped) spiculum ; head, showing 

 oral orifice with six papillfe leading into the oesophagus — the papillae 

 are armed with minute lancet-pointed teeth ; also two preparations 

 showing the difterent stages of the development of the eggs. 



I have also sent you what I take to be an " Ainphistoma conicum " 

 from the rumen of the sheep. Mr. Krefft (our curator of the Museum) 

 says it is a larva of a distoma. I maintain that it is a sexually matiu'c 

 animal, and have named it "^. conicum." Yom' opinion on it will be 

 received with thanks. 



I have also sent yoia four preparations of a " shrips " which has 

 attacked the whole of our deciduous trees and shrubs, causing the 

 leaves to assume a brownish colour-. The segments of its body do not 

 correspond to the shrij)s I have been accustomed to examine. I have 

 isolated one of its wings, and prepared it for your inspection : no 

 doubt of its being a " Thysanoptera," but I have declined to name it. 



No. 24 is a pretty little aphis (larva) from the gum (Eucalypti) 

 leaf ; it is generally found between two leaves glued together. I do 

 not know its name, therefore would feel obliged if you could name it 

 for me. AU the other preparations you will find described in the 



* Secretaries of Societies will greatly oblige us by writing their report legibly 

 — especially by printing the technical terms thus : H y d r a — and by " underlining" 

 words, such as specific names, which must be printed in italics. They will thus 

 secure accuracy and enhance the value of their i^roceedings. — Ed. ' M. M. J.'
