Atlantic Ocean (Sundev.), Ascension Island (Lesson), Red Sea (von 
Heuglin), Cocos Islands and Sunda Strait (Leiden Museum), Torres Strait 
and north Australia (Gould), Paumotu group, Honden Island (Peale), Phoenix 
group, McKeans Island (Graffe). Dr. Pickering observed this species on the 
last-named island also, as well as on Gardner and Wake Island and in the 
vicinity of the Sandwich Islands, below l67°30' west longitude. It there¬ 
fore seems not improbable that this species reaches as far as the coast of 
the Americas. The "Texas" on the tag of our individual is therefore un¬ 
doubtedly correct, although we cannot state this with absolute assurance. 
The Sula dactylatra is a similar story. Bryant assigns this bird to the 
Bahama Islands, at least including our species. Without comparing the 
specimens we cannot say whether Disporus eyanops from the Berlin Museum 
from Peru is genuine. 
Peale found this species breeding in August on Honden Island and in 
January on Enderby Island. Thus breeding is not limited to a specific 
season, as with the related species. The birds had not made a real nest, 
but the single egg lay on the bare sand or earth. In one nest two eggs 
were found. According to Gould this species nests in large numbers as 
well on Raines Island on the north coast of Australia and lays only one 
egg. This latter is a dirty white, shot with reddish brown. As Peale 
indicates, it receives this latter color through external influences. 
Bryant gives S. dactylatra as breeding from Santo Domingo Rock (Bahamas), 
but gives the number of eggs as two. 
In the Facific Ocean we know of the following localities up to the 
present time: Society Island, Huaheine, Oriadea (Forst.), Marquesas Is¬ 
lands (Jardine), Paumotu group, Honden Island, Enderby Island, Gardner 
Island (Peale) and the Phoenix group, McKean Island (Peale, Gr&ffe). Gray 
also indicates the Friendly Islands as an area. Gray also mentions this 
species among the birds of New Zealand; it would thus extend at least south¬ 
ward past the Tropic of Capricorn. 
D. piscator is identical to D. sula in habits. As the latter it is 
a very gregarious bird, which dives very skillfully and feeds on fish and 
crustaceans. In August Peale found hundreds of pairs nesting on Honden 
Island (Paumoto group). The rather loosely built nests were placed in and 
on bushes and some of them still contained eggs. The picture was the same 
on Enderby Island in January. Some nests already contained well developed 
young, while freshly laid eggs were found in others. Mostly there was only 
one egg or one young. McGillivray also gives one egg as the usual number. 
It is white in color. McGillivray found in May on Raine Island off the 
north coast of Australia only one egg; the nesting seemed to be over. Sal- 
vin investigated the nesting places of this booby in May on the coast of 
Honduras. Nesting activities thus do not seem to be limited to a specific 
season. A detailed report on this is given by Peale, McGillivray and Salvin 
(Ibis 1864, page 379).
