118. Ceblepyris azurea, (Cassin.) 



Graucalus azureus, Cassin, Proc. Acad. Philada. 1851, p. 348. 

 Two specimens in the collection from the Gamma, and so far as I am informed 

 the only known specimens except that formerly received from Dr. Macdowell, 

 and described by me as above. It is with much gratification that I record the 

 second occurrence of this species, which is quite peculiar amongst the African 

 birds of this group, and is strongly distinguished by its uniform blue plumage. 

 The present specimens are fully adult, being rather larger than that described 

 by me, and have the quills uniform clear black, without the white transverse 

 lines at the end, which are in the original specimen, and seem to mark a 

 younger bird. Total length about 8 inches. The general appearance of this 

 bird is not unlike that of the young or immature plumage of Irena puella of 

 Asia. 



119. Dicrurus coracinus, Verreaux. 



Dicrurus coracinus, J. & E. Verreaux, Rev. et Mag. Zool. 1851, p. 311. 

 From the Camma and Ogobai, and strictly identical with specimens from Mr. 

 Verreaux, in the museum of this Academy, 



120. Dicrcrcs atripennis, Swainson ? 



Dicrurus atripennis, Swains. B. of W. Afr. i. p. 256? 

 Several specimens which I doubtfully refer to this species. It is smaller than 

 the dimensions given by Swainson as above, the total length being about 8 

 inches, but is evidently nearly allied, if not identical with his species. This 

 bird has the tail but very slightly forked, and bears relations also to my D. 

 aculeatus and to D. Ludwigii, Smith, of Eastern and Southern Africa, both of 

 which are now before me. D. atripennis is not in the Academy collection. 



121. Sigmodus rufiventris, Bonaparte. 



Sigmodus rufiventris, Bonap. Rev. et Mag. Zool. 1853, p. 441. 

 Several specimens from tlie Ogobai and formerly from the Moonda. Sexes 

 alike, except that in the female the head above is clear white, without the tinge 

 of cinereous generally to be seen in specimens. This species is rather smaller 

 and quite distinct from S. caniceps. Temminck. 



122. Laniarius cruentus, (Lesson.) 



Vanga cruenta, Less. Belanger's Voy. Zool. p. 256, (1834.) 

 " Harcolestes hypopyrrhus, Bonaparte," Verreaux, Rev. et Mag. Zool. 

 1855, p. 419. 

 Lesson, Cent. Zool. pi. 65. 



Very fine specimens of this beautiful species are from the Ogobai and Rembo 

 and formerly from the Moonda. The female is similar to the male in general 

 characters, but is rather smaller and has the colors less distinct. 



123. Laniarius chloris, (Dumont.) 



Laniua chloris, Dumont, Diet, des Sci. Nat. xi. p. 226, (1826.) 

 Malaconotus Peli, Bonaparte, Consp. Av. i. p. 360, (1850.) 

 Laniarius lepidus, Cassin, Proc. Acad. Philada. vii. p. 327, (1855.) 

 The description of Lanius chloris, as cited above, is not sufficient to identify 

 it with this or any other species. In applying this name to the bird now before 

 me, I rely entirely on the conclusion of Dr. Hartlaub, in Orn. W. Afr., p. 109, 

 and necessarily disregarding the statement made by the Prince Bonaparte that 

 L. chloris is a second species of the genus Ixonotus, Verreaux (Comptes Ren- 

 dus, Acad. Paris, 1854, p. 533.) 



From the Camma, and received in all the collections from Mr. Duchaillu. 



124. Dryoscopus affinis, G. R. Gray. 



Dryoscopus affinis, G. R. Gray, Ann. & Mag. Nat. Hist. 1837, p. 489. 

 Specimens from the Ogobai and others from the Moonda, that I cannot dis- 

 tinguish from others in the Acad. Coll. from Zanzibar.
