 "Bucco scolopaceus, Temm. Mus. Lugd." Bonap. as above. 

 Barbatula stellata, Fraser, Proc. Zool. Soc. London, 1843, p. 4? 

 Numerous specimens which appear to be this species, but apparently not 

 mature. From the Camma and Moonda. 



170. Gymnobucco calvus, (Lafresnaye.) 



Bucco calvus, Lafres. Rev. Zool.. 1841, p. 241. 

 A specimen in ttie present collection seems to be this species, though the 

 dimensions are rather larger than as given in the description above cited. 

 From the Ogobai. 



171. Gymnobucco fuliginosa (Cassin.) 



Barbatula fuliginosa, Cassin, Proc. Acad. Philada., 1855, p. 324. 

 Gymnobucco Bonapartei, Verreaux, Cab. Jour., 1855, p. 102 ? 



Numerous specimens have now been received from Mr. Duchaillu, not one of 

 which has the head above or any portion of it naked, nor are they in several 

 other respects as described by Mr. Verreaux as above. My present opinion is 

 that ornithologists are in error in regarding the two names above cited as sy- 

 nonymous. Sexes alike, and presenting no other characters than as given by me 

 in the description referred to above. 



From the Camma and Ogobai and formerly from the Moonda. 



A fine specimen of Gymnobucco Peli, Hartlaub, is in the Acad. Coll., having 

 been received from the Leyden Museum through the kindness of the late illus- 

 trious naturalist, Temminck. It is specifically quite distinct from either of the 

 species here given, though the investigation of the birds of this curious genus 

 is not without difficulties.
