on the Parrots. 105 



I have never seen an example of N. septentrionalis, but 

 Dr. Hartert informs me that in the Tring Museum there are 

 four specimens from the North Island sufficiently distinct 

 from the South-Island bird. Still it appears that it is not 

 always easy to perceive the difference if single specimens only 

 are compared. The specific value of N. septentrionalis is, 

 in my opinion, open to question. 



Nestor esslingi Souance (Cat. B. xx. p. 8). 



The value of N. esslingi as a species also appears ques- 

 tionable. 



Nestor norfolcensis Pelz. (Cat. B. xx. p. 10); Lorcnz, 

 Verh. z.-b. Ges. Wien, 1896, p. 199 ; Forbes & Robinson, 

 Bull. Liverp. Mus. i. p. 5, pi. i. (1897). 



First Dr. Lorenz, then Dr. Forbes and Mr. Robinson 

 (//. cc), have expressed some doubt as toN. norfolcensis being 

 different from N. productus ; but as the two birds inhabit two 

 different islands, I should say that they would probably be 

 separable.

 Lorenz, Verh. z.-b. Ges. Wien, 1896, p. 199 ; Sclat. Ibis, 

 1896, p. 590; Orn. Monatsb. v. p. 9 (1897). 



Canon Tristram mentions specimens of this bird, now 

 extinct, in the Norwich, Cambridge, and Liverpool (Derby) 

 Museums ; Dr. Sclater has inspected one in the Gottingen 

 Museum, and another is stated to be in the Museum at 

 Birmingham. 



Fam. II. LoriidjE (op. cit. p. 18). 



Many additions have been made to this family since the 

 publication of the ' Catalogue/ but only a few forms can 

 stand as really distinct species, and many of them are scarcely 

 of the rank of subspecies. 



The family has been the subject of an illustrated mono- 

 graph by Dr. Mivart, who has figured several species for the 

 first time, but the most important additional information 

 relating to it is that published by Mr. Rothschild and 

 Dr. Hartert.
