prominent rim of the nostril were reduced a little, the nose and face 

 would precisely resemble the same parts in V. formosus ; and it a 

 mere scrap of membrane were taken from the margin of the wing 

 near to the toes, reducing it to the base of the latter, the change 

 would be complete. 



The more important difference therefore consists in the presence 

 of an additional premolar in the lower jaw, and the absence of one 

 in the upper jaw. 



Mr. W. II. Flower exhibited a flying fish (Exocetus volitans), to 

 which was attached a specimen of Penellns Blainvillii (Milne- 

 Edwards, Nat, Hist, des Crustaces) — Leoneopenna Blainvillii of 

 Lesueur. The latter was 2^ inches long ; the head and three horn- 

 like processes were buried in the muscular mass on the right side of 

 the spinal column of the fish, and the whole of the exposed part 

 gave lodgment to a colony of little Cirripeds — Conchoderma virgata, 

 Spengler, sp. (Darwin's Monograph of Cirripedid) ; these were of 

 various sizes, the largest measuring 9 lines in length. 



When first caught they were all living, and being placed in a basin 

 of sea-water, exhibited beautifully the characteristic motions of the 

 Cirri ; while a circulation was also observed in the Lerncead. 



The specimen was taken in the Atlantic Ocean, about 5° 1 7' south 

 latitude, and brought home by Mr. Walter Crisp, Surgeon to the 

 ' Monarch,' East lndiaman.

Dr. Gray, F.R.S., V.P., in the Chair. 



Mr. Gould exhibited a drawing of a very remarkable Bat which 

 had lately been transmitted to him from Melbourne, Victoria, by 

 Dr. Ludwig Becker, under the impression that it was a new and unde- 

 scribed species, but which proved to be identical with the Molossus 

 australis of Dr. Gray, characterized more than twenty vears ago from 

 the unique example contained in the Museum of the United Service 

 Institution. Mr. Gould remarked that the receipt of this drawing 

 was of especial interest, inasmuch as it proved that the animal is a 

 native of Australia, a fact which, from the circumstance of no other 

 example than the one referred to having been hitherto found in that 

 country, had been disputed ; the form being Brazilian.
