406 THE ARCTURUS ADVENTURE 



pale green sea-urchins were dotted everywhere, so that it was not 

 possible to sit on any stone, and in another place plucked six large 

 holothurians. Three or four sharks came around to look at us, but 

 except for a baby, about two feet long, that played with the end of 

 the harpoon, none of them showed any disposition to molest us. Sea- 

 lions once or twice gave us a start, as they shot down from the sur- 

 face to look more closely at us. 



On Gardner there were finches singing, doves were abundant, and 

 mockingbirds as tame as usual. Saw some of the Tropidurus lizards, 

 which seem larger here than elsewhere in the group, and with more 

 yellow in the markings, such as a line down the back. Three Am- 

 blyrhynchus caught are much more reddish than any we have seen on 

 other islands. 



Scattered about were small greenish rain pools deep among the 

 rocks, and in them were countless Branchipus and big ostracods. 

 On Hood Island much fresh water was found, one pond a half-mile 

 in length being seen. Fresh-water crustaceans were collected, in- 

 cluding Apus. Insects were numerous, and Serge got a good many 

 grubs and caterpillars. There were many goat skeletons, and one of 

 the sailors shot a large male. 



Attempted to use the small dredge from one of the motor-launches, 

 but found the bottom of the bay too irregular to make it possible, as 

 it is heaped with lava almost as thickly as is the land. 



This evening flyingfish were again with us in flocks, and dozens of 

 the green Calosoma beetles flew across the mile of water to the 

 ship. Very few moths came. A twenty-minute plankton haul from 

 a motorboat brought in a greyish pink mass of copepods, megalops, 

 ctcnophores, siphonophores, doliolum, sagitta?, pteropods, lucifers, 

 schizopods, radiolarians and stalk-eyed shrimps, — quite a pelagic haul. 

 This emphasizes the excellence of this place as a site for a year's in- 

 tensive study. 



April 27th. Exploring party to small, nameless island in bay, 

 which is now named Osborn Island. 



April 28th. Another party to albatross rookery brought back two 

 adult birds alive for the Zoological Park. Another small island ex- 

 plored. 



As coal and water are getting low, we start toward Panama to- 

 night. 



April 29th. Took sounding and temperatures this morning. The 

 sounding wire broke and lost over a thousand feet of wire. Petersen 

 sent down to 800 fathoms, a metre net to 400 fathoms. In the 

 Petersen were large maroon Medusae, with very long tentacles, huge 

 scarlet shrimps, and some medium-sized ones, a small Melamphaes 

 nigrofulous, and some pink sagittas. 



The metre net held Oneirodes, Melamphaes, another mucous-headed 

 fish, and small shrimps, a few worms, a very large scarlet ctenophore.
