pale horn-colored bill, and the pale rose-red tinge of the under parts of the body. 

 The cinereous plumage above, is paler than that of L. excubitor, and it is without 

 the white patch on the middle of the sccondiric.<!, which is so obvious in that spe- 

 cies. It is more nearly related to L. meridioiialis, but is smaller and much 

 lighter colored. 



2. Lanius pallens^ nobis. 



Form. Bill rather weak, wings and tail rather long, but with the general form 

 of typical Lanius. About the s\ze oi L. viinor, Gm. 



Dimensions. Total length of skin from tip of bill to end of tail about S inches, 

 wing 4, tail 4| inches. 



Colors. (Specimen not in mature plumage.) Rump and entire under surface 

 pure white. Head above and back cinerous, wings black, with a large patch of 

 white on the middle of the primaries, and with the secondaries edged and broadly 

 tipped with white, tail, with the two external feathers on each side white, with 

 the shafts black, others black with white tips, very narrow on the four central 

 feathers. 



A black stripe through the eye, above which is a stripe of white. 



Bill and tarsi dark horn-color. 



Hab. Fazogloa, Eastern Africa. 



Obs. This species considerably resembles the preceding, but differs in having 

 the rump white, and appears to be, so far as preserved specimens can be relied 

 on, a smaller and more slender bird ; the bill is not so long nor powerful. Two 

 specimens are in the Rivoli collection, neither of which are fully adult. 



3. Laniarius quadricolor, nobis. 



Form. Much resembling that of L. gutturalls (Baud.) but is smaller, and the 

 tail more rounded. Wings short, rounded, fourth, fifth and sixth primaries longest 

 and nearly equal. 



Dime7isions. Total length of skin from tip of bill to end of tail, about 7J 

 inches, wing 3 J, tail 3i inches. 



Colors. 5 Adult. Generally resembling those oi L. gutturalis {Baud.) but 

 with the abdomen and ventral region yellow and the basal portion of the tail 

 olive green. Entire superior surface of the head, body, and wings olive green, 

 which is also the color of a basal third of the external, and of three -fourths of 

 the central tail feathers. Throat fine scarlet, stripe through the eye and wide 

 pectoral band, black; beneath the latter a badly defined band of yellowish scarlet? 

 fading into the rich greenish yellow of the abdomen, under tail coverts yellowish 

 scarlet. Bill black, paler at the base, tarsi and feet pale brown. 



5 young. Resembling the adult, but with the tail entirely green, and the 

 throat, under parts of the body and inferior tail coverts pale greenish yellow; a 

 trace of black lines on the feathers of the breast, and of scarlet on those of the 

 throat. 



Hab.Voit Natal, Eastern Africa. 



Obs. Of this beautiful bird two adult males and several young birds are in the 

 collection of this Academy. They are from the collection of Mr. Verreaux of 

 Paris, and were acompanied by this significant memorandum, "considereecomme 

 differente de la gutturalis.'' 1 have invariably found that M. Verreaux's opinion 

 of species is of the greatest value, in fact almost infallible.
