21st June, 1883. — A paper »On the Structure of the Hard Parts of the 
Fungidaec, part 2, Lophoserinae, was read by Prof. Duncan. — A com- 
munication was read from Mr. H. G. Doran »On the Malleus of Rhytina 
Stellerix, the same being based on a specimen obtained in the voyage of the 
»Vega« and exhibited in the Swedish Department of the International Fishe- 
ries Exhibition under the charge of Prof. Smitt of Stockholm. The author 
concludes that this auditory ossicle in the extinct Northern Sea-cow (Rhy- 
tina) is larger than in the Manatee (Manatus) and therefore it is the largest 
and bulkiest malleus to be found in the whole section of the animal King- 
dom where such a bone exists. In the character of its body it resembles that 
of the Manatee rather than that of the Dugong (Halicore), while in the ma- 
nubrium it differs in AAytina from the other Sirenia and is far more gene- 
ralized. — »On the Testis of Limulusc formed a communication from Mr. 
W. B. S. Benham. He describes the structures in question noting the 
apparent isolation of many of the spermatic sacs and the probability that 
they are not diverticula of the spermatic duct, but secondarily acquire con- 
nection therewith, the two structures being independently developed. He 
remarks that in no Crustacean do the ducts of the generative glands form a 
network, whereas in the King Crab as in the Scorpion and other Arachnids 
they dc. — There followed a paper »On the Mollusca of H.M.S. ‚Challenger ‘« 
(part XX) by the Rev. R. Boog. Watson. This contains a continued de- 
scriptive account of the Family Bullidae, dealing with the genera Afys and 
Scaphander, along with the group Aplysudae, genus Dolabrifera.— J. Murie.

April 25th, 1883. — The following [zoological] papers were read: — 
1. Notes on a collection of Fishes from the Burdekin and Mary Rivers, 
Queensland, by William Macleay, F.L.S., etc. Fiftytwo species of fishes 
are here recorded as having been taken by Mr. Morton, of the Australian 
Museum, within the mouths of the above-named rivers. Of these, Mr. Mac- 
leay classes 18 as sea fishes, 11 as salt water fishes occasionally entering 
rivers, 7 as fresh water fishes occasionally visiting the sea, and 15 entirely fresh 
water fishes. The new species described are Serranus estuarius, Therapon 
Fuliginosus and parviceps, Diagramma labiosum, Corvina argentea, Caranx 
compressus, Cybium semifasciatum, Platycephalus Mortoni, Eleotris planiceps, 
Atherinichthys maculatus, Mugil Ramsayi, Chatoéssus elongatus, Anguilla mar- 
ginipinnis, and Taeniura Morton. — 2. By J. J. Fletcher, M.A., B.Sc., 
»Notes on a viviparous Lizard«. The author’s attention had been drawn to 
the subject during last January, when he obtained at Burrawang several 
examples of female lizards in an advanced stage of pregnancy. The embryos 
were from 2 to 3 inches long, enveloped in a thin and transparent chorion 
quite devoid of the calcareous matter with which it is more or less impreg-
