A specimen vvas eshibited of tlie Mušk Duck of New Holland, 

 Hydrobates lobatus, Temm. It had recently been presented to the 

 Society by Lieut. Breton, R. N., Corr. Memb. Z. S., who entered into 

 some particulars respecting its habits. He stated that these birds are 

 so extremely rare, that he savv only thrėe of them during his various 

 excursions, \vhich extended over tvvelve hundred miles of country. 

 He has never heard of any instance in which more than two were 

 seen together. They are met vvith only on the rivers, and in pools 

 left in the othervvise dry beds of streams. It is extremelydifficult to 

 shoot them, on account of the readiness vvith which they dive ; the 

 instant the trigger is drawn, the bird is under waler. 



Some observations by Dr. Hancock on the Lantern-^y and other 

 Insects of Guiana were reacl. 



The v\'riter concurs with M. Richard and M. Sieber in regarding 

 as erroneous the statement of Madame Merian, that the Lantern-Jly, 

 Fulgora lanlernaria, Linn., exhibits at night a briiliant light, and 

 remarks that the whole of the native tribes of Guiana agree in treating 

 this story as fabulous : it seems to be an invention of Europeans de- 

 sirous of assigning a use lo the singular dia))hanous projection, re- 

 scmbliiig a horn iantern, in front of ihc bead of the insect. He also 

 States that the Fulgora: rarely siiig.
