sliown isj I believe, luiicjue, and tlie others are very rare. 

 They are : ( '. cantutor and custuneiceps, A. siqjerciliaris, and 

 atbif/ularis. 



''Other eggs shown are those of Acrocephalus tujrlcola 

 and A. concinnens, generally considered to be snbspecies of 

 the same species, bnt probably quite distinct, for whilst the 

 two birds vary practically in )iothing but their wing-forniula, 

 they breed over a huge area together, though the former 

 makes a Reed-Warbler's nest in swamps, and the latter lays 

 in rose-])ushes high up on the open pasture-lands above 

 them. The eggs are indistinguishable. 



"The remaining Warblers' eggs are shown on account of 

 their great rarity, many being unique or almost so. They 

 are : Graminicolu hen<ialensis striata (taken by Capt. E. 

 G. Herbert in Siam), Acanthoptila nepalensis, Phaetornis 

 locHstelloides, Phyllergates coronatus, Horeites hrunneifrons, 

 Urosp/tema squamiceps, Phi/lloscoptis humei humei and P. h. 

 prarnium, Pliylluscopus nitidiis viridanus, P. n, plambeitarsus, 

 and P. proregalus. 



'" Finally, I show three species of the Uegulid^e : (1) Regulus 

 rcyiilus anytorum, tiie eggs of which are too well known to 

 need description, though I would draw special attention 

 to the two finely spotted clutches; (2) Cephalopijrus Jiani- 

 vdceps, which lays tiny bright blue eggs in holes of trees 

 sometimes 40 feet from the ground ; and (3) LeptupoicUe 

 obscura sophice, a tiny Waiblei-like bird which makes a nest 

 (one exhibited) like that of a Long-tailed Wren placed in 

 the thorny scrub-bushes, a few inches high, which cover the 

 great uplands in Tibet where it is found. 



"Many of the eggs shown I owe to the great generosity 

 of the following gentlemen. Those from Siam were ob- 

 tained by Mr. J. W. F. Williamson and Captain E. CI. 

 Herbert, nearly all the Burmese eggs by Mr. E. M. D. 

 Mackenzie, and those from Ceylon by Mr. W. E. Wait. 

 It is with the greatest pleasure I acknowledge these mag- 

 nificent gifts, in most cases gifts made with no expectation 

 of any retnrn." 



Mr. Stuart Baker also exhibited, on behalf of Captain C. 

 11. S. Pitman, a fine series of the eggs of Chettusia leucura,
