structed of grass-stalks. They are, however, of the same 

 form, and are as artfully made as the others.' 



"Heef Hooyman likewise states, that besides the lawet, 

 other species resort to the same caverns, which are 

 named momomo, bocrong-itam, bocrong-zoekve, end lintjc, 

 ' These,' he adds, ' are very similar to each other, except- 

 ing the second, which has the head larger; and the feath- 

 ers of all are entirely black. The nests which they con- 

 struct are black and friable, composed of a light down.' 

 (Agglutinated '?) ' An opinion prevails that the presence 

 of these birds is injurious to the caverns, on which account 

 they are driven away as much as possible.' Another writer 

 in the same volume of the Bataviaasch Genootschap, men- 

 tions the momos or boerongitam (thus bringing together AI. 

 Hooy man's first two species,) as a large kind with plumed 

 tarsi, indicating thus a true cypselus, which is probably the 

 constructer of the nests assigned by Dr Horsfield and others 

 to the line hi. Assuredly however, the C. fuciphaga, 

 (Thunberg,) linchi or lintye of the Javanese, identical upon 

 comparison with Javanese specimens, would appear to be 

 the sole producer of the numerous nests gathered on the 

 rocky coasts of the Bay of Bengal : and the often quoted 

 notice by Sir G. Staunton, in his account of the Earl of 

 Macartney's Embassy to China, must refer either to C. 

 fuciphaga, or to an entirely new species, which is hardly 

 to be supposed in the locality. For he remarks . 

 ' The birds which build these nests are small grey swal- 

 lows, with bellies of a dirty white. The white belly is char- 

 acteristic of C. fuciphaga ; and this particular species 

 occurs abundantly on parts of the coast of the Malayan 

 Peninsula, in the Nicobar Islands, and the Mergui Archipel- 

 ago, and so high as on certain rocky islets off the southern 

 portion of the coast of Arracan, where the nests are annual- 

 ly gathered and exported to China. From all this range of 

 coast we have seen no other species than fuciphaga, nor 

 does it appear that any other has been observed ; and we 

 have examined a multitude both of the adults and of young 

 taken from the nests, collected in the Nicobars and pre- 

 served in spirit, all of which were of the same species. 

 Still, what appears to be C. nidifica inhabits the mouru
