264 . [November, 



As to the true position of the group, I quite agree with M. de Lafresnaye, who 

 first described the greater part of the species, that its natural place is among 

 the true wrens near the the genus Thryothorus, though pointing through the 

 closely-allied forms Heleodytes and Donacobius, towards the mocking-birds 

 {3Iimus.) 



The following is a list of the species of Campylorhynchus, which I consider 

 to rest on good authority : 



1. C. scolopaceus, Spix, Av. Bras. i. pi. 19, fig. 1. (Opetiorhynchus furdinus, P. 

 Max.) from Brazil : one specimen in the Academy's collection. The synonyms 

 of this bird in Prince Bonaparte's Conspectus, have been somehow mixed up 

 with those of the last species of the genus next preceding it. Spix has figured 

 it with tolerable accuracy. Turdus variegatus, of Gmelin, is] sometimes con- 

 sidered to be identical with this species. 



2. C. hyposticius, Gould, P. Z. S., 1855, p. 68, from Eastern Peru. An ally 

 of the preceding, but having the body below much more thickly covered with 

 spots. The only specimens I have seen of it were those received by Mr. Gould, 

 which were obtained by Hawkswell, on the Ucayali. 



3. C. unicolor, Lafr., R. Z., 1846, p. 53. (^Pieolapies scolopaceus, Lafr. & D'Oorb., 

 Syn. Av. in Mag. de Zool., ISST, p. 46. Anumbius scolopaceus, D'Orb. Voy., p. 

 256), from Bolivia. Two specimens of this bird are in the Academy's collection. 

 They may be distinguished from C. scolopaceus, to which they are most closely 

 related, by their nearly uniform white under-surface. 



4. C. unicoloroides (I) Lafr., R. Z., 1846, p. 316, from Bolivia. I am not ac- 

 quainted with this species. It would seem, from its curious name, to be closely 

 allied to the last. 



5. C. zonatus, (Less. Cent. Zool., t. 70.) A Mexican species not uncommon in 

 collections. The Academy possesses three examples, one of which, was ob- 

 tained by Mr. Pease, in the province of Vera Cruz. 



6. C. zonatoides (!) Lafr., R. Z., 1846, p. 92, from New Grenada. I have not 

 yet seen this bird in very perfect plumage. There is one specimen in the 

 Academy's collection probably referable to this species. 



7. G. mcgalopterus, Lafr., (Des Murs, Icon. Orn., p. 54.) A large species, re- 

 cognized by its being wholly spotted and barred with black and white. There 

 are examples in the Academy's collection, probably from Mexico. 



8. C. pallescens, Lafr., R. Z., 1846, p. 93. One specimen in the Academy's 

 collection, which I take to belong to this species, seems to be closely allied to 

 the preceding, but distinguished by its nearly uniform head, more obsoletely 

 spotted under-surface, and differently marked tail. It is labelled " Guyaquil." 



9. C. nuchalis, Cab. Orn. Notiz. in Weigm. Archiv. I., p. 206. This bird is 

 very like 0. meyaloptcrus, but much smaller in size, and with the head and 

 nape unstriped. There are examples in the Academy's collection from Vene- 

 zuela, and I have often seen it from Trinidad. 



10. C. brevirosiris, Lafr., R. Z., 1845, p. 339, from Bogota. I have not met 

 with this species. 



11. C. brunneieapillus, (Picolaptes b)'unneicapillus,Lsifv., et Cass. B. Cal. pi. 25, 

 p. 156), from Texas and Northern Mexico. There are specimens of this bird 

 and of its eggs in the Academy's collection. The latter are rather peculiar in 

 coloring, and somewhat resemble those of the European Redbreast {Erythacus 

 rubecula.) 



13. C. capistratus, (Picolaptes capisiratus, Less. U. Z., 1842, p. 174: Picolaptes 

 rufinucha, Lafr. R. Z., 1845, p. 339, et Less. Descr. d. Mamm. & Ois., p. 285), from 

 Southern Mexico and Central America. 



13. C. humilis.
