INTRODUCTION 5 
definitely ascribes to Peru nine species of marine algae, which are 
probably reducible to eight, but he describes and figures several 
from Chile which have since been found to extend to Peru. 
In April, 1830, Alcide d’Orbigny landed at the seaport Arica, 
then in Peru, though now under the control of Chile, but we do 
not know that he collected any algae there. However, in the 
summer of 1833 he explored the region of Callao, where he secured 
a number of species of algae, including several that were new to 
science. Abel Aubert du Petit-Thouars, captain of the frigate 
Vénus and afterwards a vice-admiral in the French navy, was at 
Callao in May and June 1837 and again in May and June 1838 
and made collections of seaweeds there. These Peruvian algae 
collected by d’Orbigny and by du Petit-Thouars were reported 
upon by Montagne in 1839 in his “ Florula Boliviensis,’’* in which 
twenty-eight species of algae are attributed to the coast of what 
is now Peru. 
Іп 1839, the year of the appearance of Montagne's “ Florula 
Boliviensis," J. М. von Suhr published a paper entitled “Beiträge 
zur Algenkunde,"1 in which two species from Peru are described 
as new and in the following year, in another paper under the same 
ийе 1 three more Peruvian species are added. 
Charles Gaudichaud-Beaupré visited Callao and vicinity on 
the French frigate L’ Herminie in 1831 (?), and again, in July 1836, 
as naturalist of the corvette La Bonite, he made collections of 
algae at Callao and Paita. The algae secured on both of these 
visits were included іп Montagne’s герог || оп the cryptogamous 
plants collected on the voyage of the Bonite. In this work sixteen
