A specimen was exhibited of the Musk 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 saw only three of them during his various 

 excursions, which extended over twelve hundred miles of country. 

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

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

 left in the otherwise dry beds of streams. It is extremely difficult to 

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

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



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

 Insects of Guiana were read. 



The writer 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 brilliant 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 to the singular dia|)hanous projection, re- 

 sembling a horn lantern, in front of the head of the insect. He also 

 states that the Fulgone rarely sing.
