This is a very interesting new form discovered by Dr. Meyer in tlie Arfak Mountains in North- 

 western New Guinea. It is remarkable also for a white spot on the Shoulder, so concealed generally as- 

 to have escaped the Observation of Dr. Meyer in describing the species, of myself in doing the same for the 

 'Catalogue' and of Mr. Keulemans in drawing the plate. It was only discovered by Dr. Meyer himself 

 when the type came to be mounted in the Dresden Museum.

I have found Dr. Meyer's series of Cuckoo-Shrikes very useful in the preparation of the fourth 

 volume of the British Museum Catalogue of birds, since the Dresden coUection contains, several species 

 which we do not possess in England. At the same time my good friend Count Salvadori has also lent 

 me the skins collected by the Italian travellers during the last few years, and thevefore the series at my 

 disposal has been very considerable. 



The last Monographie account of the Camyophagklce was one by Dr. Hartlaub in the 'Journal für 

 Ornithologie' (1864, pp. 435—446, 1865, pp. 153—173), and since that date considerable additions have 

 been made to the number of species known. 



The Caterpillar- Catchers or Cuckoo-Shrikes form a natural family of birds, leaning towards the 

 Prio7iopid(B and Mmcicapidae, their chief characteristic being the stiffened shafts to the feathers of the rump, 

 which makes the latter feel prickly when the thamb is geutly pressed against them. The genera cannot 

 be called well-defined, as the characters that separate them are, as a rule, rather slight: this can be seen 

 by comparing the latin diagnoses given by Dr. Hartlaub in bis Monograph one with the otber. Mr. Gray 

 in his 'Handlist' has solved the difficulty as usual by mergiug the whole family in one big genus Cam- 

 pephaga, only allowing the distinctness of the genus Pericrocotus. 



Genus 1. Artamides, Hartlaub. 



Distinguished from true Graucalus by the enormously stout bill, of which the culmen exceeds the 

 tarsus in length. The type of the genus is A. Ucolor, according to Dr. Hartlaub, but on comparing this 

 Celebean species with other big-billed Cuckoo-Shrikes I cannot find how they are to be generically sepa- 

 rated, and I therefore keep all the species with the culmen longer than the tarsus in the genus Artamides.

6. c. (f 9 Rubi, New Guinea, May 1873. 

 The female from Rubi has sligthly paler tips to the tail-feathers, the quill-lining being also pale 

 fulvous or fawu-colour. In the fully adult bird the latter part of the wing is white, and the light tips 

 to the tail-feathers are not seen. The female differs from the male in not having the black chin-spot and 

 in having the lores grey instead of black. It is a fine and handsome species, in some respects like a gigantic 

 Graucalus hoyeri but without the black throat of the latter.
