XOVITATES ZOOLOGICAE XXIII. 1910. 295 



Phalacrocorax carbo carbo (L.) 



Generally larger, with larger bill ; underside deep blue-black. 



Hab. Shores of North Atlantic, from Nova Scotia to Southern Greenland, 

 Iceland, Faroe Islands, British Isles, coasts of Norway, and thence to the Kola 

 Peninsula. 



Phalacrocorax carbo subcormoranus (Brehm) 



Smaller, with smaller bill ; underside steel-black, with a distinct greenish 

 gloss. 



Hab. Central Europe, north to the Baltic (formerly nesting in Blekinge and 

 Denmark, still found in North Germany), west to Holland and coast of France, 

 south to the Mediterranean (Italy, Dragonera),the Danube Valley, Black Sea basin, 

 and thence eastwards to Central Asia. 



The few pairs of cormorants which formerly bred on the Channel Islands 

 probably belonged to this form as well. It will be interesting to compare adult 

 British Cormorants, and especially specimens from all the breeding-places in Great 

 Britain, in order to find out definitely whether both forms occur regularly. Some 

 specimens which I have seen seemed to be intermediate, others indistinguishable 

 from P. c. subcormoranus ; but most adult breeding birds, and probably all, belong- 

 to P. c. carbo. 



I am obliged to Professor Lönnberg for readily answering my questions, and 

 thankful to 0. Haase for giving an extract, in translation, from the Swedish article 

 in "Fauna och Flora," in the Ornith. Monatsberichte, 1916, p. 45. 



MORE ERRONEOUS QUOTATIONS AND OTHER ERRORS. 



By ERNST HARTERT, Ph.D. 



IN Nov. Zool., pp. 112-14, I have called attention to some wrong quotations and 

 careless double references, under totally different species, to one and the same 

 name. These do not only occur in vol. xxiv. of the Catalogue of Birds, but 

 also in other volumes of that immortal work, and in other books as well. 



The first part of vol. xxv., dealing with the " Gaviae " or better Lari, was 

 written by Howard Saunders, who had for many years made the study of the Gulls 

 and their allies his speciality. One therefore expects in this portion of the work 

 a masterpiece ; it is doubtless very well compiled, but by no means without errors, 

 and not free of misprints and wrong quotations. I will only call attention to a few 

 mistakes I came across in the palaearctic species. 



1. Larus naesius Linne, Syst. Nat. Ed. XII. i. p. 255, is quoted twice as 

 a synonym both of Larus marinus, on p. 243, and as one of Rissa tridactyla, on 

 p. 306, the quotation being in both cases rather inexact — in the first case as Syst. 

 Nat. p. 225 (without edition and volume), in the second as Syst. Nat. i. p. 225 

 (without mentioning the edition). There is very little doubt that the second 

 quotation is correct, the name Larus naevius being taken from Brisson, Orn. vi. 

 p. 185, pi. IT, fig. 2, while the size, the delicate grey back and the small hind-toe 

 without nail alone make it impossible to refer the name to Larus marinus, which
