Type locality. — Vera Cruz, Mexico. 



Range.' — From Mazatlan and Rosario in Sinaloa south through. 

 Colima, Jalisco, and Guerrero to the Isthmus of Tehuantepec in 

 Oaxaca and to Tonala in Chiapas. 



Reported from: Guerrero, Cocoyul, Tierra 

 Colorado, Cajones, Chilpancingo, Rio Balsas, 

 and Iguala (Gadow); Oaxaca, Salina Cruz 

 (Gadow). 



Remarks. — The co types of Bufo marmoreus 

 (M.N.B. Nos. 3529-31) were taken at Vera 

 Cruz by Ferdinand Deppe, according to the 

 label on the jar. These specimens have the 

 light-colored vertebral stripe with irregular 

 longitudinal light line. The supraciliary and 

 postorbital crests are very low. The dark 

 spots on the upperparts have a narrow white 

 edge; the parotoids are light colored above 

 and dark laterally; the underparts are white; 

 the metatarsal tubercles are small; and the 

 skin of the upperparts is studded with minute 

 warts. The head-and-body lengths of the 

 three cotypes are 58.2, 56.5, and 56.5 mm., 

 respectively. 



John Xantus de Vesey was appointed United States consul at 

 Manzanillo, Mexico, in 1863. From March, 1863, to March, 1864, he 

 remained in Colima, although his consular appointment was revoked 

 prior to August 11, 1863. On February 29, 1864, his last shipment 

 from Manzanillo was assembled, and he states in Part V of his field 

 catalogue that this collection included 1,000 alcoholic specimens 

 without labels. Evidently Xantus traveled a great deal while residing 

 in Colima, as an entry in his journal dated June 25, 1863, states that he 

 had traveled 700 miles that month. He made numerous trips to 

 the city of Colima, and in all probability collected the cotypes of 

 Bufo argillaceus (U.S.N.M. Nos. 27763-64) in the vicinity of that 

 city. These cotypes are fairly well preserved, but are somewhat 

 distorted. It is possible that the preservative may have been allowed
