Parus atricristatus castaneifrons and P. hicolor texensis. 

 Dr. Allen discusses the true status of these birds at full 

 length, and, after a careful study of all available niaterial_, 

 accepts Mr. Ridgway's view that " the birds shewing mixed 

 characters are hybrids '' and not " geographical intergrades.^' 

 A somewhat similar case in the Oriental Region is that of 

 Coracias indicus and C. affinis (see Blanford, Fauna of 

 Brit. Ind., Birds, iii. p. 106). 



2. Berlepsch on the Birds of Cayenne. 



[On the Birds of Cayenne. — Part II. By Hans, Graf v. Berlepsch. 

 Nov. Zool. XV. p. 201.] 



We have now before us the second part of Graf von 

 Berlepsch's excellent memoir on the Birds of Cayenne, of 

 which we have already noticed the first {' Ibis/ 1908, p. 616). 

 In the two parts together 626 species are included. In the 

 second part the author begins with the Trochilidae, of which 

 he enumerates 38 species as found in Cayenne. 



Additions and corrections follow the List, and it is stated 

 in a " Summary " that we may add about 140 more species 

 which, although not yet recorded from Cayenne, are likely 

 to be found there. We are therefore "justified in comput- 

 ing the number of species that belong to that country to be 

 about 766/' 



" Penelope granti " is proposed as a new name for the 

 species of Guan from British Guiana called P. marail 

 by Mr. Ogilvie-Grant (Cat. B. xxii. p. 495), the P. marail 

 of Gmelin being probably = P. jacupeba. 



3. Cheeseman on the Lesser Frigate-bird. 



[Notice of the Occurrence of the Lesser Frigate-bird (Fregata ariel) in 

 North Auckland District. By F. F. Cheeseman. Trans. New Zealand 

 Inst. xl. p. 265 (1897).] 



In BuUer's " Supplement " to his ' Birds of New 

 Zealand ' it is stated that there is only one authentic record 

 of the occurrence of Fregata ariel in New Zealand. The 

 capture of a second specimen of this bird in the peninsula 

 north of Auckland and various particulars about it are now
