examples of JJ. dumetoria from Chili (Santiago and Valley del Yeso) 

 with which it has been compared. All the latter also show quite dis- 

 tinct paler streaks on the hind neck, which are not observable in the 

 Gregory Bay bird. 



Family PTEROPTOCHID^. 



24. Hylactes tarnii King. 



Port Otway ; two specimens. 



25. Pteroptochus rubecula Kittl. 

 Port Otway ; four specimens. 



26. Scytalopus magellanicus (Lath.) ?. 



Otter Bay, one adult female; Port Churruca, two young. 

 I am unable to determine whether these specimens are 8. magellanicus 

 or 8. obscurus (King). According to Dr. Sclater (Ibis, 1874, pp. 192- 

 194), these two species are "easily distinguishable," the latter "by its 

 larger size, more cinereous color, longer tail, and the faint bars across 

 the rump and lower belly." Yet the alleged difference of size is by 

 no means shown by the measurements which Dr. Sclater himself gives, 

 which are as follows : 



S. magellanicus ("smaller"). Wing, 2.20; tail, 1.50. 



S. obscurus ("larger"). Wing, 2.00; tail, l.GO. 



The adult female from Otter Bay measures : wing, 2.00 ; tail, 2.30. On 

 the other hand, an adult female from Santiago, Chili, determined by 

 Dr. Sclater as 8. magellanicus, has the wing 1.95 and the tail 1.60, while 

 it has the hinder parts of the body, both above and below, distinctly 

 barred with dusky — a character said to distinguish 8. obscurus. 



It is very evident that the birds of this genus need careful revision ; 

 but lacking sufficient material I am unable to give them further attention 

 at present. 



27. Scytalopus albifrons (Landb.). 



Port Otway, two specimens, adult female and young, the former 

 agreeing minutely with a specimen from Valdivia, Chili, received from 

 the Xational Museum of Chili. 



This species is certainly distinct from S. magellanicus, as Mr. Allen has 

 already shown (Bull. Am. Mus. Nat. Hist., vol. II, No. 2, p. 99). 



Family TEOCHILID^. 



28. Eustephanus galeritus (Mol.). 

 Port Otway, two specimens. 



Family PICID^E. 



29. Dryobates lignarius (Mol.). 



Laredo Bay, one specimen. 



30. Campephilus magellanicus (King). 



Laredo Bay and Saudy Point, two specimens.
