Recently published Ornithological Works. 645 



English ornithologists appear to have visited. Mr. Helms 

 now continues his series of contributions to this subject by 

 an account of the birds of East Greenland obtained during 

 Amdrup's expedition of 1898-99, and of the collection made 

 by the observers of the Meteorological Institute at Angmag- 

 salik (on the east coast at about 66° N. lat.) during several 

 years. The result is a complete list, with remarks added, of 

 the birds of East Greenland, altogether 51 in number, of 

 which 16 are more or less casual visitors. To this follow 

 some notes on recent ornithological events in West Green- 

 land, amongst which is a record of the occurrence of the 

 iC King-bird " of North America (Tyrannus intrepidus) at 

 Arsak on the west coast (61° N. lat.), in September 1900. 



Mr. Helms determines the Bean-Goose of East Greenland 

 as belonging to the form commonly called Anser hrachij- 

 rhynchus.

We have not been in the habit of noticing in these pages 

 the yearly volume of the l Zoological Record/ because we 

 assume that workers in every branch of Zoology who employ 

 their pens must be well acquainted with that useful publica- 

 tion, and must consult it more or less frequently. But 

 having been favoured with a " presentation-copy ^ of the 

 volume of the International Catalogue of Scientific Litera- 

 ture which relates to Zoology, and which occupies nearly the 

 same ground as the ' Zoological Record/ and having been 

 invited to express our opinion on it, we have great pleasure 

 in accediug to this request. 



It is probably known to most of our readers that one of 

 the great difficulties met with by workers in all branches of 

 Scieuce in these days is to ascertain what their fellow- 

 workers have done and are doing. This difficulty is much 

 increased by the enormous number of scientific periodicals
