mental result, and it is therefore probable that M. Berthier 

 himself has observed the fact, in which case it cannot be 

 doubted ; but the result is so important that any one possess- 

 ino- pure manganese who can verify the result and give an ac- 

 count of the degree of temperature at which the change takes 

 place, will be doing a service to science. The great point will 

 be to secure the perfect absence of iron or nickel from the man-, 

 o-anese. With respect to cobalt, I have already stated that 

 when pure, I cannot find it to possess magnetic properties at 

 common or low temperatures.

Dec. 8, CPECIMENS were exhibited of various Birds chiefly from 

 1835. 1^ the Society's collection, which Mr. Gould regarded as 

 hitherto undescribed. At the request of the Chairman he pointed 

 out the distinguishing peculiarities of the undermentioned species : 

 viz. Phcenicura plumbea, Pyrgita cinnamomea, Merula castanea,\Sauro- 

 phagus Swainsonii, Brachypus gularis, Merula Nestor, lanthocincla 

 pectoralis, and lanth. albogidaris ; and also the following new genus. 

 Stenorhynchus. 

 Rostrum capite longius, gracile, compressum, subfornicatum ; 

 mandibulfi superiore leviter emarginata, culmine in frontem de- 

 pressissimum producto. 

 Nares ovales, apertse. 

 Alee breviusculse, subrotundattE ; remige Ima brevissima, 4ta lon- 



giore ; 5ta et 6ta 4tam subaequantibus. 

 Cauda mediocris, rotundata ; rectricibus decern ? 

 Pedes robusti : acrotarsis subscutellatis ; halluce wnjfMeque pos- 

 tico fortibus, tarsum longitudine subsequantibus, digito inter- 

 medio brevioribus. 

 Pluma moUes. 



Stenokhynchus euficauda. Sten. suprii sordide saturate hrun- 

 neus, rufo caudam versus tinctus; caudd, secundariis, scapulari- 

 busque saturate rufo-brunneis ; subtus brunnescenti-cinereus, in 

 rufo-brunneum ad latera vergens. 



Long. tot. 94- poll.; rostri, 14; alee, 4-|; Cauda, Z\; tarsi, 1. 



Rostrum nigrum ; pedes brunnei. 



Hab. 



As only one specimen of this bird has yet been seen, it is doubt- 

 ful whether it may not possess twelve tail-feathers ; but, after a care- 

 ful examination, Mr. Gould can discover no more than ten.
