the exception of a single pair of Saddle-backs, Larus marinus, no 

 large gulls, other than the herring-gulls, were seen by either of 

 us. All the inhabitants at Manan, with whom we conversed on 

 this subject, stated that there was a bird, called by them Farmer 

 Gull, larger than the herring-gull, with a dark head and shoul- 

 ders, which was occasionally found breeding in solitary pairs on 

 the rocky islands. This description of the farmer gull is proba- 

 bly correct as far as it goes, more particularly as their attention 

 had been called to a specimen, unfortunately destroyed before 

 our arrival, which had been procured for Dr. Brewer. When at 

 Manan, we were told that we should find this bird much more 

 numerous at the Seal Islands, near Yarmouth. On ai'riving at 

 Yarmouth, we still heard of the Farmer Gull, and the same 

 description was given of it as at Manan, but we were told that it 

 was seldom seen there, though quite abundant at the Bay Cha- 

 leur. What species this bird may prove to be I do not know, 

 but am inclined to think, if a described species, it is a black- 

 backed gull in immature plumage, though the inhabitants who 

 had been in the habit of seeing this gull, did not consider it the 

 same as their so-called Farmer Gull. 



t Larus marinus. One pair seen at Big Mud Island. 



t Larus atricilla. Two pair seen at Green Island near Yar- 

 mouth. Their nests were not discovered, but the birds were shot, 

 and evidently, from the enlarged state of the oviducts of the 

 females, had recently finished laying. This is another of the 

 birds which are common on the shore south of Cape Cod, and 

 mentioned by Richardson as inhabitants of the fur countries ; they 

 are not known to breed between Cape Cod and the Bay of Fundy. 



* Lestris Richardsonii. One pair seen near Green Island. 



TItalassidroma Leachii. This bird was found breeding in 

 the manner described by Dr. T. M. Brewer, on some of the small 

 islands near Manan ; and also on the islands near Yarmouth, 

 including the Mud Islands, mentioned by Audubon as the breed- 

 ing places of the Wilson Petrel. 



Mormon Arcticus. Only one specimen of this singular bird 

 was seen near Manan, but at the islands in the neighborhood of 

 Yarmouth they are still quite abundant. The only place where 

 we found them breeding was at Gi-een Island. One egg was 

 found here laid in a crevice in the rocks. Several burrows were
