AVIFAUNA OF LATSAN, ETC. 



307 



Professor Schauinsland's explorations have further added the following birds to the 

 Laysan list, the majority of which are only more or less irregular winter visitors :— 



1. LlMOSA LAPPONICA NOViE-ZEALANDIiE, Gray. 



6 . Laysan, 5. 11. 1896, in the Tring Museum. Several more were procured, which 

 are in Bremen. 



2. Heteropygia acuminata (Korsfield). 



One specimen. (Bremen Museum.) 



3. Calidris arenaria (Linn.). 



One specimen. (Bremen Museum.) 



4. Thing a amepicana, Cass. 



( Teste Schauinsland, ' Drei Monate auf einer Koralleninsel,' p. 101, 1899.) 



5. Crymophilus eulicarius (Linn.). 



(Teste Schauinsland, /. c.) 



6. Anas poschas, Linn. 



6 ad. Laysan, 7. 11. 1896. (Bremen Museum.) 



7. Spatula clypeata (Linn.). 



Laysan, October, November, January. (Bremen Museum.) (Antea, p. 275.) 



8. Daeila acuta (Linn.). 



Laysan, three specimens. (Bremen Museum.) (Antea, p. 275.) 



9. Nettion carolinense (Gm.). 



1 ? . 27. 10. 1896, Laysan. (Bremen Museum.) The females of N. crecca and 

 N. carolinense are appareutly indistinguishable ; but N. crecca is not recorded from the 

 Pacific coasts of America. 



10. QUERQUEDULA QUERQUEDULA (Linn.). 



(Teste Schauinsland ; but I am inclined to consider it more likely to be Q. discors.) 



11. MARECA AMERICANA (Gm.). 



2 juv. Laysan, 15. 10. 1896. (Bremen Museum.) 



12. Clangula alpeola (Linn.). 



6 juv. 15. 1. 1897. (Bremen Museum.) 



13. Larus glaucescens, Naum. (or L. nelsoni, Hensh. ?). 



I have examined one young bird, now in the Bremen Museum, procured on Laysan 

 by one of Professor Schauinsland's correspondents. The outermost primary is nearly 

 pure white on the outer web, while the inner web shows a distinctly separated darker 

 and a lighter half. Under tail-coverts mixed irregularly white and ashy brown. Wing 

 16-2 inches! The small size points rather to L. nelsoni than to L. gtaucescens ; but 

 probably the specimen is a young female of the latter. Schauinsland (I. c. p. 101) 

 mentions this Gull as L. glaucus, but it does not belong to the latter form. (Antea, p. 286.)
