but the specimen figured was given to me by my unhappy and celebrated friend, the Count de 
Raousset Boulbon *) , who found it in company with a Productus semi-reticulatus on the banks of one 
of the creeks that rise in the Sierra of Arizona and flow into the Rio Gila. I have also seen 
specimens found at the sources of the Colorado Chiquito. I did not find this species in the Rocky 
mountains. De Koninck cites it in the vicinity of St. Louis.

I) Gaston Raoulx de Raousset Boulbon, born at Avignon, France, 2 Dec. 1817, was condemned 
by a Mexican Court Martial as a conspirator and rebel, and shot the 12"' Aug. 1854 at Guaymas, 
Mexico. During my stay at San Francisco in March and April 1854, I was intimately acquainted 
with de Raousset. One evening , at the house of our mutual friend , the late Mr. Dillon , then Consul 
General of France for California, de Raousset gave me two fossils; one w'as the Productus costatus and 
the other the Productus semi-reticulatus , that he had found in the dry bed of a creek in the Sierra de 
Arizona. He also showed me a very fine manuscript map of Sonora, made by him, which was by far 
the best I have ever seen of that country so little known. The conqueror of Hermosillo intended to 
publish this map, but as I have never heard more of it, I suppose the manuscript may have been lost 
during the last stormy months of his life. In all my various wanderings I have never met with so brave 
and chivalrous a man as de Raousset. With three or four hundred thousand dollars ho would have conquered 
Sonora and the whole of Mexico , and have become a second Fernando Cortez. Son of one of the no- 
blest families of Provence, he followed freely the movement of the age, and valued labor more than 
his escutcheon; in California he was known only as Gaston Raousset, and did not disdain to gain a 
subsistence as Stevedore in the harbour of San F'rancisco. His tragical end , although foreseen by him- 
self and his numerous friends , was nevertheless an infamous act of the Mexican government and its 
President Santa Anna. F'rance also was wanting to her own dignity in this affair, and de Raousset died 
without the power of claiming the protection of the flag of his country. England does not thus abandon 
her children , and wherever an Englishman’s life or even property is threatened , he is sure to be sus- 
tained by his government backed by the whole nation. By' this course England has covered the world 
with her colonies, while France has only made unsuccessful attempts.
