variety intended. Thus Lanhis ludovicia7ius excubitorides is omit- 

 ted from the catalogue, but Mr. 'Henshaw is quoted as reporting- 

 L, hidoviciajius gambeli ixoxw the '*East slope" [of the Sierra Ne- 

 vada Mountains]. Mr. Ridgway, in replying to a letter of interro- 

 gation on the shrikes in California, wrote as follows: '* Two forms

which occurs in the eastern and sometimes also the central portions 

 of the State; and L, L ganibeli, which belongs chiefly to the coast 



district," etc. 



With the few exceptions noted above, the work seems to furnish 

 us with a complete list, so far as now known, of the birds of this 

 region, together with many valuable notes on the migration and 

 distribution of nearly all the species considered^ A large part of 

 these notes is the result of many years of earnest field work on the 

 part of Mr. Belding, so that we feel doubly indebted to him for this 

 most valuable production. c. a. k. 



On a Collection of Birds made by Mr, Clark P. Streator in Brit- 

 ish Columbia, with Field Notes by the Collector, By Frank M. 

 Chapman.* The region from which this collection was made has 

 been hitherto almost unexplored ornithologically, and this list of the 

 birds of the region is consequently of special value. In the words 

 of the writer : *' Mr. Streator's collections from the interior develop . 

 two interesting facts— first, a re-appearance here,west of the Rockies, 

 of the Eastern type; second, a westward extension in the range of 

 certain Eastern species." The remarkable north-westward exten- 

 sion of Eastern forms is a fact which has a most important bearing 

 on the geographical distribution of animals. 



The Auk for October contains nothing relating to Pacific Coast 

 birds except a description by William Brewster of **A New Sub- 

 species of the Solitary Sandpiper " from Lower California. There 

 is one unfortunate circumstance in this description, which is that it 

 is based solely on autumnal birds in young plumage. Unless the 

 subspecies is exceptionally strongly marked this is a very dangerous 

 proceeding, especially when an adult male from the same region '' m 

 every respect is identical with autumnal adults =«^ * ^ from the 

 Eastern States.
