22 THE AUSTRAL AVIAN RECORD [Vol. II. 



the South Atlantic, no specimens from that locaUty had 

 been examined by him." 



In the Vienna Museum I noted a strange conspicillated 

 Petrel, and upon examination the following data was 

 found attached — 



" B. 32° 42' Long. 12° I' Atlantic Ocean, coll. by 

 Zelebor Novara Exped " 

 and was named 



" F. conspicillatus." 



Upon reference to the Reise Novara Vogel. p. 143, 

 1863, the data is given as: " Atlantischer Ocean, zwischen 

 Siid-Amerika und dem Cap. Mannchen (131) am 11, 

 September, 1857, unter 31° 40' s. B. und 12° 41' w. L." 



This specimen differs from the Austrahan-kiLled 

 specimens which agree with Mathews's figure (I.e.), in 

 that the broad band across the top of head only comes 

 in front of the top of the eye and does not coalesce with 

 the band which runs from the chin-spot to the back of 

 the head under the eye. This lower band is also dis- 

 connected from the chin-spot. The bird was also smaller 

 and browner than P. cequinoctialis, and my examination 

 of all the specimens available leads me to the following 

 conclusions : — 



Two species have been confused under the specific 

 Procellaria cequinoctialis, the spectacled form being a 

 distinct species. 



The conspicillate birds, in addition to the spectacling, 

 are smaller and browner, and when carefully criticised, 

 smaU but constant differences in the bill are seen to 

 exist. Though the bill in P. conspiciUata is absolutely 

 shorter, the nasal tubes are proportionately longer ; 

 they are also shallower and more distinctly separated 

 from the laterals, and also from the feathering of the 

 fore -head by apparently dry skin ; the laterals of the 

 upper-mandible are also less inflated. It is pleasing to 

 note that although Mathews lays no stress on these 

 characters, the artist in the figures on pp. 111-112 has
