A Cassin's auklet egg collected from Castle Rock Island, off the coast of California. The original collector L. T. Stevens noted it had been incubated for one week and the idenification was made when the bird was taken from the nest. Stevens also noted it was laid in a "burrow 18 inches deep in soft dirt on top of island. A few pieces of grass in nesting cavity." Later acquired by Ernest Cutts.
