wliitisli. The general colour ubove is darker, somewhat more Ijiackish than in 

 Ai: mcifjentae. The dimensions are less, especially the bill is considerably smaller 

 and weaker, and the primaries are narrower than in the type of Ae. mayeitfae. 

 Wing 227 mm. (about 308 in Ae. magentae), tail 115 (140 in Ae. mageutae:), culmen 

 from forehead in a straight line 26 (43 in Ae. magentae), depth of bill at base 13 

 ■(loin Ae. magentae), tarsus 32i (38 in Ac. magentae), middle toe with claw 48 

 (56 in Ae. magentae), extent OlMi, length in tlic flesh 355 mm. Bill entirely black, 

 tarsus and basal half of toes flesh-colonr ; tarsus dusky at base ; distal half of toes 

 and outside of outer toe blackish. 



One adult female was caught at sea in 3' S., 118" 45' W., on January 2nd, l!)(i], 

 by Mr. H. H. Beck. (Tyjie No. 143 Beck coll., Mus. Tring). The species is named 

 after Mr. t'h. K. Wortheu, of Warsaw, Ills., U.S.A., who organised and managed Mr. 

 Beck's trip to the Galapagos Islands. 



We are much obliged to our friend ( 'omit Tommaso Salvador! in Turin for 

 kindly comjiaring Ae. wart/ieni with the tyjic of Ae. magentae in the Turin Museum 

 and giving us several notes on the latter. For references to Ae. magentae see Ihis

[Aestrelata neglecta (Schl.) ? 

 A fine female was caught at 13° lat. north, 103" 50' long. west. This bird agrees 

 with the darkest specimens of Ae. neglecta from the Kermadec Islands, e.xcept that 

 it is still darker, less brownish and more blackish than all except one. The 

 wing measures 295 mm., thus being somewhat smaller than the majority of our 

 thirty-one neglecta from the Kermadec Islands. The blackish colour on the under- 

 side of the first primary reaches almost to the tip of the underwing-coverts, while 

 in nearly all of our negleeta, with the exception of two or three, it is restricted to the 

 apical third of the feather. The identity of this bird with neglecta can only be 

 proved or disproved by a series from the same locality.]

Mr. Beck sent a series of specimens from the Galapagos Archipelago. Specimens 

 were procured near Biudloe, Barrington, and Abingdon Islands. Never more than 

 three or four were seen together. They were generally more wary than (Jccanitex 

 gracilis and Procellaria tethys. All these three sjiecies are often seen feeding 

 together, and probably all three breed on several of the islands. Harris saw quite a 

 flock of petrels about a cliff on Tower Island in December 1897, and Beck's party 

 saw all the three species near there in March lOOl.

Three specimens, one marked S, one ?, one not sexed, were obtained b}' 

 Mr. Beck at sea, 13 N., 103' W., on May 3rd, lOdl. The length is marked on the 

 label of one with 7|-, the expanse 16A in. 



These birds agree excellently with BIr. Anthony's description. The measure- 

 ments, as taken by Mr. Hartert, are as follows : Wings, 143, 143, 15(i ; tails, 70,
