Zoological Club of the Linnean Society. 419 



*' On the quinary arrangement of Nature," and the subject sub- 

 sequently underwent a lengthened discussion. 



Some observations were introduced before the meeting by 

 W. Burchell, Esq. F.L.S. on the genera Pagonias, 111. and Bacco, 

 Auct. as forming the connecting link between the Linnean genera 

 Psittacus and Picus. That gentleman stated that his inferences 

 were drawn from personal observations during his Travels in 

 Southern Africa. 



The crania of three quadrupeds from New Holland were exhi- 

 bited by Joshua Brookes, Esq. F.R. and L.S. two of which were 

 ascertained to belong to the genus Dasyurus, Geoff. On the 

 animal of the third, he requested information, and the subject 

 was referred to the Assistant Secretary. 



June 8. — Mr. Bennett recalled the attention of the Club to 

 the Crania exhibited by Mr. Brookes at the last Meeting ; and 

 stated that the specimens relative to which that gentleman re- 

 quested information, corresponded with specimens contained in 

 the Museum of the College of Surgeons, and to which the name 

 of Dasyurus ursinus had been prefixed by Professor Temminck. 

 As the Cranium, however, before the Club, differed remarkably 

 in the number of the Molar teeth from that of the D. ursinus, as 

 described by Mr. Harris, in the ninth volume of the Transactions 

 of the Linnean Society, Mr. Bennett felt some doubt as to its being 

 referable to that species. The other Crania, exhibited by 

 Mr. Brookes, were described as belonging to Dasyurus macrourus 

 and D. cynocephalus ; and it was remarkable that the description 

 of this latter animal also, as given by Mr. Harris in the same 

 paper, did not coincide with the specimen exhibited in respect to 

 the number of the molar teeth. 



A portion of a paper " On Tunicata, with a description of 

 three new species," by W. S. MacLeay, Esq. M.A. F.L.S. was 

 read by the authour. 



June 22. — The Secretary exhibited two specimens of Dro- 

 tnia Mediterranea, Leach, which were communicBted to him 

 by Mr. J. E. Gray, for the information of the Club. These 

 specimens were found in Billingsgate market, by that gentleman,
