couchii Baird, Scaphiojms rectifrenis Cope, and Bufo debilis Girard 

 were collected on this trip. In addition to the specimens collected by 

 himself, Lieutenant Couch purchased the entire collection of Dr. Luis 

 Berlandier and presented it to the Smithsonian Institution. The Rio 

 Nasas was reached in June, 1853, and on August 1, 1853, he was back 

 again in San Diego, Nuevo Leon. The exact itinerary of this expe- 

 dition is not known to the writer, for the report although written was 

 never published. A more extended account of this expedition is 

 published in the remarks under Bufo debilis (p. 52). 



On April 7, 1854, a small collection made in Chihuahua was received 

 from John Potts. Subsequent collections received from Potts in 1854 

 and 1855 contained a number of additional species, including the type 

 specimens of Eleutherodactylus longipes (Baird) and Scaphiopus multi- 

 plicatus Cope. 



An exchange with the Museum d'Histoire Naturelle in Paris some 

 time in 1855 resulted in the transfer of a few of the Mexican amphib- 

 ians collected by Adolphe Boucard. In 1860, duplicates of Mexican 

 amphibians and reptiles were received in exchange from the Academy 

 of Natural Sciences of Philadelphia. Included among them were 

 several amphibians collected by R. Montes d'Oca at Jalapa in Vera 

 Cruz. One of these was a tree frog with a small tympanum, which 

 later became a cotype of Hyla miotympanum Cope. 



In 1859, Professor Baird began to correspond with Dr. Carlos 

 Sartorius, who with his son Florentin collected a number of specimens 

 in the vicinity of Mirador and Orizaba, including the types of Hyla 

 miotympanum Cope, H. muricolor Cope, and H. gracilipes Cope. 

 From Charles Laszlo, of Tabasco, the Smithsonian Institution in 1860 

 received a small collection of alcoholic specimens. 



From the Smithsonian annual report for 1861,' one learns that a 

 collection of reptiles from "Guadalaxara" had been received from 

 J. J. Major. This shipment presumably included the type of Gas- 

 trophryne usta (Cope), a small narrow-mouthed toad described by 

 Cope in 1866. 



Following a brief expedition to the interior of Mexico, Louis John 

 Xantus de Vesey, a Hungarian, and one or more of his companions 

 settled on a homestead in Iowa, but as might have been anticipated, 

 Xantus soon tired of this. Fortunately for all concerned he had in 

 the meantime become acquainted with Dr. John F, Hammond, 

 U. S. A., who, with the assistance of Professor Baird, obtained for 

 Xantus the appointment as hospital steward in the United States 

 Army, For a part of his enlistment, Xantus w^as stationed at Fort 

 Riley, Kans., and later was transferred to Fort Tejon, Calif. Speci- 

 mens collected at these localities were transmitted to Baird, who 

 became more and more interested in his natural ability along these
