of a fresh specimen of Grey's Whale, in which the jaws had become | 
too much splintered to allow of a complete skeleton being pre- 
. pared, afforded the writer the opportunity of examining the brain, 
of which he gave a very full description with measurements. For 
comparison he had the brain of only one other species, viz., that 
of the species of Delphinus, common on the New South Wales 
coast. 
(7.) «On a New Genus of Fishes from Port Jackson,” by Wm. 
Macleay, F.L.S., &c. This paper consists of the description ot a 
large fish taken a few days ago in a Seine net at Watson’s Bay. 
It is of the family Civriitide, and somewhat allied to the genus 
Chilodactylus. The generic name given to it is Psilocvanium, from 
its naked head, and the specific name coaiz, in honor of the Presi- 
dent of the Commissioners tor Fisheries of New South Wales. 
This fish was exhibited by Mr. Morton, Assistant Curator Aus- 
tralian Museum.

Papers—(1.) ‘‘Some fishes of New Britain and the adjoining 
islands,’ by Charles W. De Vis, B.A. The names of the new 
specimens described are :—Sevvanus perguttatus and cruentus, Meso- 
prion flaviresea, Tetaroge vestita, Acanthurus zebra, Rhynchichthys, nove 
britannie, Haxpage vosea (a new genus of the Berycide), Salarias 
aquipinnis, Amphiprion Arion, Pomacentrus onyx and notatus, Nesiotes 
purpurascens (a new genus of the Labridz), Exocetus longibarba, Arius 
avmigey, Herpetichthys cobva (a new genus ot the Murenida), Tetvodon 
insularium and levis. 
_ (2.) Some results of Trawl fishing outside Port Jackson,” by 
William Macleay, F.L.S., &c. In this paper are given—1, an 
account of two trials of a large beam trawl in 40 to 50 fathoms 
water, by the order of the Commissioner of Fisheries ; 2, a list ot 
the fishes captured; and 3rd, descriptions of two new species—a 
skate—Raia austvalis, and a Gurnard—Lepidotvigla mulhalli. Mr. 
Macleay considers the result promising on the whole. 
Baron Maclay read a note on the ‘‘ Barometro Araucano”’ from 
the Chiloe Islands. He stated that this remarkable instrument — 
had been shown to him among a number of other curiosities by 
Captain C. de Amezaga, of the Italian corvette “‘ Caraciolo,” who 
informed him that it was used by the natives of the Chiloe Islands 
as a kind of barometer to foretell the approach of either dry or 
wet weather. This ‘“‘Barometro Aruacano,”’ which consisted 
merely of the shell of a crab—pronounced by Mr. Haswell to be 
oue of the Anomura, probably of the genus Lithodes—is most 
peculiarly sensitive to atmospheric changes. In dry weather it 
remains nearly white, but, with the approach of moisture, small red 
spots appear onthe shell, increasing in number and size with the 
increase of humidity, until during the wet season it becomes com- 
pletely red. 
Mr. Macleay stated that he had been informed by Professor 
McCoy, that the large shark captured at Portland, Victoria, and 
which had been spoken of at last month’s meeting of the Society, 
was the Selache maxima, or Basking Shark of the Arctic Seas, 
and that the dimensions had been correctly reported,
