[Cy. Zool. Rec. 1874, p. 27.] Notes are appended under the heads of 
nearly all the species mentioned. The paper is thus an important con- 
tribution to the ornithology of West Africa.

Describes a specimen of this species, sent for comparison with the 
author’s S. portlandica by O. Finsch. The result shows that S. longi- 
pennis is closely allied to S. hirundo and S. macrura^ but distinct from 
both S. portlandica and S. pilcii.

. Outlines of a Natural Arrangement of the Falconidce, Tom. cit. 
pp. 225-231, 8 pis. 
Professor Huxley’s arrangement of the Birds of Prey is adopted, after 
due consideration. The basis of the classification here sketched out is 
shown in a tabular form, and the points relied upon are placed in the order 
of their importance. The Falconidce are divided into two groups, Fal- 
coninoe and Buteonince, the relative positions of the scapular process of 
the coracoid and the clavicle with other characters defining tli^ese groups. 
The Falconinoe (the only section discussed in this paper) contain Fal- 
cones^ Polyhori^ MicrastureSy and IlerpetothereSy and their respective 
characters are drawn out. Lastly, the genera of Polyhori are defined. 
8 plates give drawings in outline of the chief characters relied on in this 
paper.
