2 MR. P. L. SCEATER ON AMERICAN Q.UADRUMANA. [Jail. 2, 



The following papers were read : — 



1. On the Quadrumana found in America north of Panama. 

 By P. L. Sclater, M.A., Ph.D., F.R.S. 



[Eeceived December 5, 1871.] 

 (Plates I. & II.) 



In the 'Natural History Review' for 1861*, I wrote an article 

 upon " The Northern Limit of the Quadrumana in the New World," 

 and showed that these animals range much further northwards than 

 had been then recorded in scientific works. I likewise endeavoured 

 to put together all that was then known of the distribution of the 

 species of Monkeys met with in Central America north of Panama. 



My attention has been again drawn to this subject by the receipt 

 by this Society of living specimens of several species of Quadrumana 

 from various parts of the Central-American isthmus, and by the 

 publication of an article by Dr. v. Frantzius in a recent number of 

 Wiegmann's ' Archiv,' upon the Mammals of Costa Rica t; and I am 

 now able to give some additional information as to the actual species 

 of Quadrumana which are met with north of Panama, and their 

 range and localities £.

J Our authorities on the mammals of America north of Panama are very 

 few and meagre. I am acquainted with the following only specially relating to 

 this subject: — 



a. Mexico. 



1. Wagler's "Einige Mittheilungen iiber Thiere Mexicos," in the 'Isis,' 1831, 

 p. 510, which contains notices of four mammals, and the first description of 

 Bassaris astuta. 



2. M. H. de Saussure's articles on certain Mexican mammals in the Eev. et 

 Mag. de Zool. for I860 & 1861, with supplementary notices in 1865. 



3. Von Midler's * Eeisen in Mexico,' Leipzig, 1864, which contains at the end 

 of vol. iii. a list of Mexican vertebrates. It is, however, a mere compilation, full 

 of egregious errors, and of no scientific value whatever. 



b. Guatemala. 



4. Mr. Tomes's Eeport on Mr. Salvin's collection of mammals made at 

 Duefias, in P. Z. S. 1861, p. 278. This contains an account of thirty-six species. 

 Mr. Salvin subsequently made other collections of mammals in Guatemala, 

 which were likewise entrusted to Mr. Tomes, but have never yet been reported 

 upon. 



c. Costa Eica. 



5. " Die Saugethiere Costarica's, ein Beitrag zur Kenntniss der geographischen 

 Verbreitung der Saugethiere Amerika's," von Dr. A. von Frantzius ( Wiegm. Arch. 

 1869, i. p. 248), contains notices of about sixty species, some of which are not 

 exactly determined, and others, I have good reason to believe, not quite correctly 

 named. 



d. Panama. 



6. List of Mammals and Birds collected by Mr. Bridges near David, by 

 P. L. Sclater, contains references to five species.
