Note. — ^The name Troglodytes laUfasciatus Lichtenstein(Preis-Verz. 

 Mex. Vog., 1830, 2"), has usuallj' been cited as a S3'nonym of Salpinctes 

 ohsoletus, and if really intended for this species would of course be 

 available for the pre.sent form; but the very brief description certaiid}' 

 does not afford sufficient reason for such identification, and therefore, 

 in the absence of any type specimen (which, according- to Salvin and 

 (iodman, seems to have disappeared), I am unal)le to discover the 

 slightest excuse for adopting the name in question. In fact, it would 

 have been better had the majorit}' of the new names of this much-cited 

 paper been ignored, as the reward for the author's carelessness. 



SALPINCTES OBSOLETUS PULVERIUS Grinnell. 

 SAN NICOLAS ROCK WREN. 



Similar to S. o. ohsoletus, but with larger and relatively stouter l)ill 

 and much" paler, more buffy coloration (general color of upper parts, 

 in summer plumage, pale butty broccoli brown or pale grayish wood 

 hrown). 



Adult male. — Length (.skin), 136.5; wing, 71; tail, 51; expo.sed cul- 

 nien, 20; tarsus, 21.5; middle toe, 1-1.5.'' 



« I have not been able to refer to the original paper, but in the reprint in Journ. 

 fiir Orn., 1863 (p. 57), the name is given as Intisfasciatus, not latifaseiatus, as usually 

 cited. 



^ One specimen, the type. Mr. Grinnell gives average measurements of eight speci- 

 mens (sexes not separated) as follows (his figures being converted into millimeters): 



Length (l)efore skinning?), 152.4; wing, 69.8; tail, 55.1; culmeu (exposed?), 18.3; 

 (lci)th of bill at nostril, 4.3; tarsus, 21.6.
