TYPE SPECIMENS OF BIRDS 413 



Ridgway based this thrasher upon an indeterminable number of cotypes, 

 but, in a footnote, stated that measurements were taken from four adults, 

 and it must be assumed that not more than this number of specimens lay 

 before him. 



The three listed above seem unquestionably to deserve the status of co- 

 types, but it is perhaps no longer possible to decide which of two represents 

 the fourth of the series. These are Nos. 51523 and 51524. The former was 

 sent to William Brewster in 1873, given his private label with the number 

 562 (which number does not appear in his private register, now preserved 

 at the Museum of Comparative Zoology) , and at some time returned, without 

 extant explanation, to the U.S. National Museum. If returned prior to the 

 time Ridgway described M. c. occidentalis, it presumably formed part of 

 the series, but this cannot be proved. No. 51524, on the other hand, sup- 

 posed never to have left Washington, has vanished without trace. In the 

 circumstances, it seems to me best to treat as cotypes only Nos. 37326, 

 51525, and 52789. 



No. 52789 spent a period as part of Ridgway's private collection, during 

 which time it lost its original label and was given Ridgway's number 1990.
