184 MR. H. SAUNDERS ON THE LARIN^E. [Feb. 5 



of a dusky hood, has been confused with L. fuliginosus of the Gala- 

 pagos Islands ; but its much slenderer bill, tarsi, and feet will 

 at once distinguish it from tbe latter, even in youth ; whilst in 

 the adult the clear grey of tbe underparts and the white blending 

 into grey of tbe forehead and head, distinguish it from any other 

 known species of Gull. Mr. Fraser's plate above cited gives a very 

 fair idea of the adult ; but very old birds are much lighter about the 

 upper parts than his example.

Hab. Galapagos Islands, 



This stoutly built and well-marked species appears to be restricted 

 to the Galapagos group. Mr. Salvin's illustration above cited will 

 probably prevent further confusion between this bird and L. mo- 

 destus ; but it is most extraordinary that the late Mr. G. R. Gray 

 should have confounded it with L. heermanni, when he had the 

 type of the present species before him. Specimens are exceedingly 

 rare in collections ; and of the eggs and nestlings no examples are 

 known. 



Although this species differs from the preceding ones in having 

 a hood in its adult plumage, yet its other affinities seem to indicate 

 that its proper place is here and not with the ordinary hooded 

 Gulls.
