nor streams of any kind, nor other source of supply of water than 

 those mentioned, except in the rainy season, when cavities in the 

 rocks are often filled with rain-water. Artificial wells are also dug 

 through solid limestone." 



I now add Mr. Gaumer's notes on the species which he has 

 collected \ 



1. TuRDUS GRAYi, Bp. ; Lawr. Ann. Lye. N. Y. ix. p. 199; 

 Salv. & Godm. Biol. Ceutr.-Am., Aves, i. p. 18. 



Native name " Euiseiior." This bird is rather common in all 

 parts of Yucatan, and is much prized as a pet for its sweet song. 

 It is found alike in towns and forests. It utters no cry when 

 approached, and is said to sing only in June. Though I have spent 

 the summer in Yucatan, I have never had the j)leasure of hearing 

 this bird sing. 



2. Galeoscoptes carolinensis (L.) ; Lawr. I. c. p. 204 ; 

 Salv. & Godm. Biol. Centr.-Am., Aves, i. p. 26. 



This bird is very rare ; only a few specimens have been seen, all 

 of which were in the cities of Merida, Izamal, and Tizimin. It is 

 very shy, and frequents low clumps of bushes along the stone 

 fences. 



3. Melanoptila glabrirostris, Sclat. ; Salv. & Godm. Biol. 

 Centr.-Am., Aves, i. p. 27, t. 3. f. 2. 



Exceedingly rare. 



4. MiMUs GiLVUs (Vieill.) ; Salv. & Godm. Biol. Centr.-Am., 

 Aves, i. p. 36. 



Mimus gracilis, Lawr. I.e. p. 199. 



Native name " Chico," or " Zenzontl." The name of " Zenzontl" 

 is generally given in IMexico to all the species of Mocking-birds. 



[This is the only species of Mimus of which I have seen specimens 

 from Yucatan. — 0. S.']

 ' Nomenclator.' I have also added the references to Mr. Lavtrenee's paper on 

 the Birds of Yucatan (Ann. Lye. N. Y. ix.), and the names of several species
