AMPELID^l. 77 



nine are inserted on the hand, and the third is the longest, in E. horsfieldii, nasutus, and 

 cmullatus. The rectrices are graduated in all. 



5. Calyptomene viridis, RAFFLES (Rupicola viridis TEMM.). Pterylosis exactly as in the 

 second group of Eurijlaimus, but with nineteen remiges, of which ten are on the hand, and the 

 third is the longest. 



6. Pipra. Following the example of WAGLER (Isis, 1830, p. 928), I unite under this name 

 the genera Pipra, Rupicola, and Phibalura ; and the more readily, as none of the species 

 examined by me exhibited any differences in the pterylosis. They possess a rhombic saddle, the 

 elongated space of which is enclosed posteriorly only by two converging rows of contour-feathers 

 standing singly or two together, which unite at the caudal pit to form the narrow rump- band. 

 The pectoral band in all is furnished with a branch slightly separated at the end. They have also 

 nineteen or twenty remiges, of which ten are on the hand, and amongst these often some of 

 singularly abnormal structure, with remarkably diminished vanes. 



In P. (Ampclis) carnifex, in which the first three are the longest, the fourth and fifth are thus 

 peculiarly formed ; in P. rupicola the first and the fourth, here the longest. This species has 

 perhaps only eighteen remiges, and nine on the hand. I have examined also P. peruviana, 

 P. flicauda, P. caudata, and P. (PJdbalurd) flavirostris, in which no such remiges occur. 1 The 

 last-mentioned species has a forked tail and acute wings, in which the second primary is the 

 longest ; the two preceding species have graduated tails, and the fifth primary is the longest. 

 Moreover, in Phibalura the outer toes are not united at the base, which renders its generic 

 separation more admissible. 



b. With a simple saddle in the spinal tract. 



(In the covering of the tarsus the members of this section agree exactly with the typical 

 Passerinse ; the posterior laminae, consequently, are not wanting. BDRM.) 



7. Procnias ventralis TEMM., PL Col., 5. The saddle is not rhombic, but parallel- sided, 

 although pointed at both ends, and thus carried over into the anterior and posterior parts of the 

 spinal tract. The outer branch of the pectoral tract is but very slightly free at the end. 

 Eighteen remiges, nine on the hand ; first three equal and longest. 



8. Hypothymis LIGHT. The saddle in H. chrysorrhcea is elongated, rounded on the sides ; 

 in H. C(Bsia shorter and broader, with acute lateral angles. The pectoral branch is slightly separated 

 at the end. There are nineteen remiges, of which ten are on the hand : the first small, the second 

 and third abbreviated, pointed ; the fourth, fifth, and sixth equal, longest, and rounded at the end. 

 The tail is twice as long as in Procnias. 



9. Bombycilla. Pterylosis exactly that of the second species of Hypothymis, that is to say, 

 a rhombic, acute-angled saddle, and a straight pectoral branch, scarcely separated at the end. 

 Nineteen remiges, of which ten are on the hand : the first remarkably small ; the second and third 

 longest. Tail short, but somewhat longer than in Procnias. The horny laminre at the ends of 

 the secondaries and rectrices are singular, but well known. B. yarrula, B. americana. 



1 The Piprine genus Machteropterus also presents a very abnormal structure in the primaries, for 

 a description of which see P. Z. S., 1860, p. 90, and Ibis, 1862, p. 175 P. L. S.
