276 General Notes. [April 



whole top of the head blackish and the belly and flanks bright 

 rusty rufous. A specimen labelled Guayaquil (locality probably 

 not correct) in the U. S. National Museum, agrees fairly well with 

 the type, but has the sides of the belly and flanks more olive rufous. 

 I have dedicated this new form to Dr. Harry C. Oberholser. 



GENERAL NOTES. 



Procellariidse versus Hydrobatidae.— The discovery that the generic 

 name Procellaria Linnaeus belongs to the group commonly called Maja- 

 queus Reichenbach (cf. Mathews, Novit. Zool., XVII, December, 1910, 

 p. 497) makes necessary a change in the family name Procellariidce. On 

 account of the adoption of Thalassidroma Vigors for Procellaria auct. nee 

 Linnaeus, the family name Thalassidromidce has been used (Committee of 

 Brit. Ornith. Union, List Brit. Birds, ed. 2, 1915, p. 281). Since, however, 

 the generic name Thalassidroma has been properly retired in favor of 

 Hydrobates Boie, the family name Thalassidromidce must accordingly be 

 altered to Hydrobatidce, as has already been done by Mr. Mathews in his 

 'Birds of Australia,' (Vol. 2, No. 1, May 30, 1912, p. 9).— Haery C.

Lorg-tailed Jaeger in Indiana. — A beautiful specimen of the Long- 

 tailed Jaeger (Shrcorarius longicandus) , taken at Millers, Ind., November 

 30, 1918, was seen by me in a Chicago taxidermist's shop. Knowing 

 of only three previous records of the bird's appearance in the Chicago 

 area, I purchased the bird and it is now in my collection. The first 

 record was made by Mr. Stoddard of the Field Museum and the other 

 two by Mr. Woodruff of the Chicago Academy of Sciences (Auk, Vol. 

 35, p. 234) . Mr. Cory of the Field Museum kindly verified its identity 

 and as this forms the fourth instance of the bird's occurrence within 

 our boundaries it should be of interest. It is in the immature plumage 

 with the tail-feathers only partially developed. — Nathan F. Leopold 

 Jr., Chicago, III. 



Larus canus brachyrhynchus in Wyoming. — A Wyoming specimen 

 of Larus canus brachyrhynchus, a male in juvenal plumage, has for many 

 years been in the collection of the Biological Survey, in the United States 

 National Museum. It is No. 141395, U. S. Nat. Mus., and was taken 

 on Lake Fork, a tributary of the Green River, at an altitude of 10,000 feet 

 in the Wind River Mountains, Wyoming, on August 28, 1893, by Mr.
