CATALOGUE OF A COLLECTION OF BIRDS FROM BRITISH EAST AFRICA BY NED DEARBORN, Assistant Curator of Ornithology. CHARLES B. CORY, Curator Department of Zoology. CHICAGO, U. S. A. May, 1909. CATALOGUE OF A COLLECTION OF BIRDS FROM BRITISH EAST AFRICA. BY NED DEARBORN. The collection of birds here treated was brought home by the Museum's last expedition to East Africa, 1905-7, made under the direction of Mr. C. E. Akeley. Most of these specimens were col- lected and prepared by Mrs. Akeley. Colors have been designated according to Ridgway's "Nomenclature of Colors." Specimens without sex marks on labels have been indicated by a ?. Occa- sional notes concerning habits were made by the collector, and are included in quotation marks. One new species is described. The type locality, if known, follows the original citation of each name. The map indicates the location of the different camps at which speci- mens were obtained. The sequence of families is that adopted by Dr. Sharpe in his Handbook. Thanks are hereby gladly rendered to the authorities of the Philadelphia Academy and the Smithsonian Institution for the loan of specimens, and to officials at the John Crerar Library of Chicago for the use of books. Besides the Catalogue of Birds in the British Museum, Shelley's Birds of Africa and Reichenow's Vogel Afrikas, the papers in the sub- joined list have been of assistance in the determination of species.

Females average slightly smaller than males, have the throat clearer white and are without spurs. One of these males, the younger judging by its shorter spurs, is paler, more cinnamomeus, than the other, its throat being decidedly cinnamon, and the black marks of its breast feathers much smaller. 3.

This specimen has been compared with a female topotype of Mr. Oberholser's 0. c. anonyma from Kilimanjaro. It is grayer on the inter-scapulum and also on the chest than the topotype, and thus tends to confirm the validity of anonyma;* but, on the other hand, the differences between anonyma and specimens of true capensis from South Africa, appear to the writer to be of a seasonal nature, and not geographical variation.

Its white flanks, black spot on abdomen and broad post-ocular lines of white meeting on the occi- put are adolescent characters.

I. in Reichenow's Vogel Afrikas, I., p. 643. But in a series of C. spar- verius there are always occasional specimens that differ from the majority in exactly the same points shown by this skin. Such oddities can be set down only to individual variation, and it is proba- ble that this bird was only an unusually small and dark example of its species. Family Strigidae. 66.

There appears to be a little uncertainty as to the correct name for this form.

On the other hand, neither specimen can be called "nigricanti-brunneum," which is set down as the ground color of the upper parts of nigricantius in the original description above cited. They do agree with nigricantius in the triangular spotting of the back, and in the white superciliary and loral areas. The chocolate-brown specimen is but sparsely spotted above, and the tips of the breast feathers are near chestnut. The gray-brown specimen has the white spots on the back more numerous and larger, showing a tendency towards bars, and the tips of the breast feathers are buff.
