58. Caprimulgus monticola, Frankl. P. Z. S. 1831, p. 11(3. 



Caprimulgus stictomus, Swinh. P. Z. S. 1863, p. 263. 

 Caprimulgus pallidus, Gray, Zool. Misc. p. 2. 

 Caprimulgus ?, Ibis, 1860, p 47, 1861, p. 30. 



South China in summer. I have a very rufous and brightly 

 marked female from Amoy, which I at first confounded with tbe 

 following bird. 



59. Caprimulgus stictomus, Swinhoe, Ibis, 1863, p. 250, 

 1866, pp. 315, 402. 



Like the last, but smaller, with the toes, especially the middle 

 one, conspicuously longer. Resident in Formosa. 



60. Cypselus pekinensis, Swinhoe, P. Z. S. 1870, p. 435. 



This pale representative of C. apus, L., comes to Pekin in large 

 numbers in April {David) to breed, and leaves early in August. A 

 bird from the Himalayas, brought home by Dr. Jerdon, agrees with 

 my specimens ; and it is probably this species, and not the true C. 

 apus, which is found in India in winter. 



61. Cypselus pacificus, Lath. Ind. Orn. Suppl. p. 58; Ibis, 

 1870, p. 89.

Cypselus tinus, Swinh. Ibis, 1870, p. 90. 



Cypselus tectorum, Jerdon. 



Hainan. I have compared my specimens with Dr. Jerdon's type 

 from Upper Assam, and with Dr. Sclater's type from Borneo in Mr. 

 Wallace's collection, and find them all to be of the same species. 



64. Ch^etura CAUDACUTA(Lath.).

It is probably this species that makes the edible nests in the ca\es
