then the shelly part being removed the green silicates remain 

 representing the sarcode that filled the chambers, pseudopodian 

 tubules and stolon passages. Of course some parts of the marble 

 retain the organic structure better than the rest." 



2. New Species of Felis. 



Professor Cornalia of Milan has lately described before the Eoyal 

 Lombardian Institute a new small species of Felis, discovered by 

 Professor Mantegazza in the high-lands of Bolivia, at an elevation 

 of 1500 metres above the sea-level, with the following characters : — 



P. villosa, cinerea, subtus et intus allida : maculis brunneis pallidi^ 

 plenis rotundatis aut ovato-elongatis, seriatim dispositis, per latera 

 corporis descendentibus ; maculis ventralibus rubiginosis aut Isete 

 fulvis ; artubus externe nigro-fasciatis, interne nigro maculatis : 

 Cauda elongata, occiput attingente, annulis latis perfectis 9 brunneis ' 

 long, tota Corp. o. 60, caudse. 45 metr. 



Hab. in Bolivia, circa Potosi et Huanahuaca. 



Por this species (which is allied to Felis hrasiliensis, F. maracapa^ 

 F. elegans, F. ?nitis) , Prof. Cornalia proposes the name Felis (Leopardus) 

 jacobita. It enters the burrows of the Viscacha (Lagostomus viscac- 

 clia) and preys upon them. — Bend. B. 1st. Lomb. i. p. 241. 



3. The White Whale, 



Professor Jeffries Wyman, the well-kno vv n anatomist of Harvard 

 College, Cambridge, U.S.A., has contributed to the seventh volume 

 of the " Boston Journal of Natural History," an accurate descrip- 

 tion of a male White Whale {Beluga leucas) which died in Mr. 

 Barnum's Museum, after having been exhibited to the public alive 

 in a water-tank for nearly two years. Prof Wyman remarks : — 



" The descriptions of this species by different naturalists are 

 quite defective, and render the identification of it quite difficult. 

 By Lacepede and Cuvier, and also by Hamilton, (Naturalist's 

 Library," Vol. xxvi. Whales, p. 204), it is described as being 

 without a dorsal fin, an error which doubtless grew out of the small 

 size of this organ. The last-mentioned author states also that the 

 " blow-hole" has its concavity backwards, instead of forwards, as in
