 Islands and Formosa, just after sunset, October 3d, 1854. Bill yellowish blue, 

 inclining to greenish about the base and on the throat. Feet light lemon yel- 

 low. Two fishes of the genus Hemiramphus were found in its maw." (Mr. 

 Stimpson.)

" Taken in the Coral Sea, January, 1854. No land nor shoal known to be 

 in the vicinity." (Mr. Stimpson.) 



138. Graculus dilophus, (Swainson.)

139. Graculus violaceus, (Gnielin.) 



From Behring's Straits. In very fine adult plumage. 

 "Behring's Straits, August, 1855." (Mr. Stimpson.) 



140. Graculus carbo, (Linnseus.) 



"Shot at Fotow Bay, Island of Ousima, May, 1855, by Lieut. Brooke.'" 

 (Mr. Stimpson.) 



141. Larus Hutchinsii, Richardson. 

 From Behring's Straits. 



"Abundant on the shores of Semiavine Straits and in the fresh- water la- 

 goons of Arikamcheche Island on the Asiatic coast of Behring's Straits, in 

 August, 1855 ; not shy and easily approached within gun-shot. The native 

 boys catch this bird with a sort of sling made of five or six strands of rope, 

 to the ends of which small stones are attached. This sling is thrown at the 

 bird usually when flying, and is frequently successful in entangling it so 

 much that it cannot extricate itself before being captured. The skins of this 

 and other birds are used by the Tchuchtchi people for clothing." (Mr. E. 

 M. Kern.) 



142. Larus melanurus, Temminck. 



" Hakodadi, Japan, June, 1S55." (Mr. Stimpson.)

Sterna macroura, Naum., Isis, 1819, p. 1847. 

 Sterna arctica, Temm., Man. d'Orn. ii. p. 742, (1820.) 

 From Behring's Straits. This is the first specimen that I have ever seen 

 from the North Pacific Ocean, but it appears to be identical with the bird from 

 the northern regions of America and Europe. 



" Semiavine Straits, Asiatic coast of Behring's Straits, August, 1855." 

 (Mr. Stimpson.) 



146. Sterxa lunata, Peale. 



Sterna lunata, Peale, Zool. U. S. Ex. Exp. Vincennes, Birds, p. 277, 

 (1st ed. 1848.) 

 From the Pacific Ocean, lat. 26 N., long. 135 E. This is a rather large, 

 black-billed species of the same group, and considerably resembling the com- 

 mon S. panaya, but is much lighter colored. It is carefully described in my 

 second edition of the volume on Quadrupeds and Birds of the U. S. Ex. Exp. 

 (1858.)
