attached to the intestuie at a point much further back than 

 in other species ; from this point a tube passes forward and 

 opens as usual. Longitudinal muscles uncommonly large and 

 strong, being in fact so broad as to cover the greater part of the 

 internal surface. 



The specimen described was obtained at the depth of thirty- 

 fathoms. 



Mr. Teschemacher alluded to the fact that a very im- 

 portant article to chemists and manufacturers, Platina, was 

 becoming scarce from the exhaustion of the localities from 

 which it has hitherto been procured. It was a well known 

 fact that much of the gold from California had more or less 

 of this mineral in combination with it. Mr. Teschemacher 

 had estimated, that as much as 5,300 oz. of it must have 

 been brought in this way to the Atlantic States.* This 

 would be a very important amount for scientific purposes. 

 Its value in the market is now about five dollars the 

 ounce. 



^ Nine mineralogical specimens were presented by Mr. 

 Alger, and eighteen from I\Ir. James Robins, of North 

 Chester, Vermont. 



The Curator of Ornithology announced the addition to 

 the Society's collection of the following specimens, namely : 

 Pyroderus scutatus, Fire-bodied Crow ; Corvus comix, 

 Hooded Crow ; Conurus squarnalus, Scaly-breasted Parrot ; 

 Jidda Jiitens, Shining Grakle ; Xanthornus dominicensis, St. 

 Domingo Troopial ; Lesies viridis, Leach's Oriole ; Qwis- 

 calus major, Great Crow Grakle ; Chrysoptilus campestris, 

 Gold-breasted Woodpecker ; Centurus slriatus, Rayed 

 Woodpecker; C. flaviveniris, Yellow-bellied Woodpecker; 

 Chloronerpes aurolentus, Brazilian Woodpecker, together 

 with a Jay, a Thrush, a Cassican, and three Parrots of 

 doubtful species, — all from Moses Kimball, Esq. in ex- 



* This he based on the separation by himself of 0.95 gr. Platina in grains 

 from one ounce of gold, sent to him from the Feather River locality; of these 

 the specimens had been exhibited before the Society.
