has a semi-obsolete bar of about i mm. The middle rectrices are 

 also less plainly barred in the mainland specimen, the bars becom- 

 ing somewhat obsolete near the shaft. 



Cerros Island Wrens were not common at any point on the 

 island, though more were seen about the pine timber on the 

 higher ridges. Mr. L. Bekling secured specimens of the species 

 several years ago, but owing to their poor plumage no attenxpt was 

 made to separate them.

Type, $, No. 7346, coll. A. W. A., Rosalia Bay, Lower California, 

 Aug. 20, 1S96. Above smoke gray; pileum and cervix between drab and 

 broccoli brown ; chin and belly white ; throat, breast and flanks approach- 

 ing drab gray; crissum buffy clay color; tail slaty black, each feather 

 marked at tip with gray. Wing, 97 mm.; tail, 136; culmen,3i ; tarsus, 30. 



The region immediately back from the beach at Rosalia and 

 Playa Maria Bays is a series of wind swept sand dunes, with 

 scarcely any vegetation. A few hardy shrubs and yuccas struggle 

 for existence and afford shelter for quite a number of Thrashers. 



A series of sixteen was secured with little effort, though the 

 present race well maintains the reputation of the species for 

 shyness. On several occasions they were seen on the beach, and 

 a few were found inland, where II. cinereus tnearnsi was more 

 common. They were nowhere so plenty as in the sand dunes.
