'My. Seebohm Exhibited an egg supposed to be that of the 

 Knot [Trijiga canutus) taken near Disco in Greenland. 



A communication was read from Mr. Osbert Salvin, 

 F.R.S.; on two new species of birds from Nicaragua, as 

 follows : — 



'' In a collection of birds recently sent by Mr. W, B. 

 Richardson from Nicaragua, several interesting species are 

 represented which, so far as I know, have not hitherto been 

 noticed in Nicaragua. Thus we find Thryophihis costari- 

 censis, the Costa Rican form of T. castaneus, as well as T. tho- 

 racicus and Thryothorus atrigidaris, botli of which, however, 

 have been noticed at Grey town. Skins of a Cyphorhiims 

 from Santo Domingo, in Chontales, differ from C. lawrencn 

 and may be described as 



'^ Cyphorhinus richardsoni, sp. n. 

 " ^ C. laivrencii affinis, sed supra pallidior, et loris, sicut 

 gula, distincte castaneis, necnon tectricibus aharura 

 minoribus vix ti-ansfasciatis distinguendns. 



" Mr. Richardson also sends a specimen of Piprites gri- 

 seiceps from Sati Carlos, which is only the second we have 

 seen ; and, along with several interesting Formicariidse, an 

 example of a new Rhopoterpe, a genus not yet included in 

 the Central-American fauna. This we propose to call 



"^ Rhopoterpe stictoptera, sp. n. 

 "J R. torquatce affinis et ejusdera statuno necnon coloribus 

 plerumque siniilibus; sed capite summo obscuriore, 

 uropygio et cauda fuscescentioribus, ]'emigibus in pogo- 

 nio externo ad apicem cervino dii^tincte notatis, maculis 

 celatis in pogonio interno cerviuis (nee albis)^ et tec- 

 tricibus majoribus late cervino terminatis distinguendns. 

 " Hah. Nicaragua ; Santo Domingo. 



•'•'We also find a single specimen of Conunis finschi, 

 originally described from Panama specimens; and a pair, 

 taken at Leon, of the pretty little Gampsonyx swainsoni, a 

 well-known bird in South America, but quite new to the 

 Central- American fauna. •'■'
