The terrestrial ecology of Malpelo and the behavior and natural history of the lizards Anolis agassizi and Diploglossus millepunctatus are described and discussed. The geology of Malpelo is briefly described and an improved map of the island is presented. The geology of Malpelo was studied and a more accurate map of the island was made by an exploration team.
The use of Navy ships is a valuable addition to the research capacity of the Smithsonian Tropical Research Institute. Part of the expedition's success lay in what its previous explorers had learned about the island. His popular article (Murphy, 1945) provides the best summary of the island's natural history.

Further surveying had to accept the island circumference and scale from the published Hydrographic Office chart. The two largest groups of these rocks are joined to the north and south of the island. At the summit the party had a view of the entire southern tip of the island.
Atop both peaks a strong breeze blew constantly in contrast to the calm conditions further down the leeward side of the island. On the less steep slope northwest of North Peak were some of the few patches of grass found on the island. Published accounts of the geology of Malpelo Island include McConnell's (1943) analysis of three rocks from the island and the field observations of Murphy (1945, also in McConnell, 1943).
The largest sea cave on the island is at the top of the fjord (Figure 7). Macurda helped me with fieldwork and Steward helped me interpret photographs of the island.

The natural history of the large anguid lizard Diploglossus millepunclatus from Malpelo Island is described. Huey of the Museum of Comparative Zoology for assistance in the preparation of this manuscript. In the case of carcasses, lizards may also have been feeding on insects attracted to the carcass.
Anguid lizards of the Genus Diploglossus in Panama with the description of a new species. Williams of the Museum of Comparative Zoology for helpful comments on the manuscript. Two of the species are also members of the latifrons series of the alpha section (Etheridge, 1960): A.
Similarly, representatives of the most primitive group of Anolis, the Lesser Antilles rocket group (alpha group, seria latifrons; Etheridge, 1960).

REMARKS.—The male specimen corresponds to the description of the unique male holotype given by Holthuis (1951). The movable finger is almost 0.6 the length of the chela and is somewhat flattened dorsally.

Sensory papillae on head relatively large; in rows below eye, on cheek, on edge of preoperculum, on operculum, on snout, and on dorsal and ventral surfaces of head TABLE 9.-Counts and measurements of the holo-. A black bar below the anteroventral margin of the eye, passing obliquely downwards over the suborbitals and jaws, and terminating in the anterior ventral spot of the series described above. RELATIONSHIP.—The general head shape, relatively high number of fin rays, and general color pattern suggest a relationship to a species complex of Chriolepis, most members of which are undescribed in the eastern tropical Pacific.
Full discussion of relationships within the genus Chriolepis and related genera of seven-spined gobiids with distinct pelvic fins is deferred pending the completion of an ongoing review by the author of all known species in the eastern tropical Pacific. COMPARISON. Chriolepis lepidotus differs from other described congeners in the eastern tropical Pacific in the extent of its scale formation; the scales extend below the origin of the dorsal fin. ETYMOLOGY. From the Greek lepidotos (scaly), referring to its squamation, the best known in the genus.
This will provide for a comprehensive systematic, zoogeographic and evolutionary treatment of the genus and its allies (briefly treated by Bohlke and Robins in the eastern tropical Pacific.

Manuscripts for serials are accepted by the Smithsonian Institution Press, subject to actual review, only through departments of the various Smithsonian museums. If submission is invited, the following format requirements for the press will govern the preparation of the copy. For easy reference, also number the taxa and their corresponding headings throughout the text; do not incorporate page references in the key.
In synonymy, use the short form (taxon, author, date:page) with a full reference at the end of the paper under "Literature Cited." Begin each taxon at the left margin with subsequent lines indented approximately three spaces. Simple tables in the text (eg columns of data) may or may not have headings, but they should not contain lines. In the bibliography (usually called "Literature Cited"), spell out book, journal, and article titles, using initial capital letters with all words except small terms such as "and, of, the." For capitalization of titles in foreign languages, follow the national practice of each language.
