The other in size and appearance exactly like a purple grape (Hyalea) with a greenish tinge at one extremity surrounding an aperture, and a distinct aperture at the other extremity.

(See illustration Hyalea figure 1.) THE ALBATROSS (Diomedea exulans).
We caught four of these birds yesterday, from which I made the following measurements: FIRST SPECIMEN.
