P. DeBenedictis 1964 16 Jan on board "Golden Bear" off southern Mexico. uniform dark on the back. The Blue-footed was very mottled on the back, greyish on the head, while below, dark wings and tail. About half way through an adult Masked Booby appeared, about the same size as the Peak toots and followed the cut of the boat 2 Linns were present. Also spotted about 70 Phalopes on the water and we came near enough a flock of 28 to see the back stripes and to hear the "kit" call of Northern. Most of the birds were flying on the water and didn't appear to be feeding.

A Riddley turtle, was seen floating on the surface near what appeared to be a kelp holdfast with some filament attached; it appear to be nibbling of the filaments. There are two thin types of flying fish about. One has the pectoral fin marked as [illegible] and is larger than another species with none or a very small pelvic fins. They are present in large schools, 50+, now, and can be seen from
