Two New Species of North American Testudinata.— 
The following species of Graptemys have been described : 
1. Graptemys geographica, Les. 1817. 
2. Graptemys pseudogeographica (Les. MSS.), Holbrook, 1842. 
3. Graptemys oculifera, Baur, 1890. Science, No. 405, pp. 262-263. 
4. Graptemys kohnii, Baur, 1890. 1. c. 
GRAPTEMYS PULCHRA Spec. nov. 
For some years I have been acquainted with two specimens of a 
Graptemys preserved at the Smithsonian Institution. Both specimens 
were collected by Dr. T. H. Bean in Montgomery, Ala., and bear the 
number 8808. One of these is mentioned in Yarrow's Catalogue 
(Bull. U.S. Nat. Mus., No. 24, 1883), as “Malacoclemmys geograp hicus." 
In 1891 I received a skull and a very large living specimen from Mr. 
G. Kohn, of New Orleans, La., of the same species. 
The coloration of the skull and neck distinguishes this species at 
once from all the others. The whole space between and behind the 
orbits is characterized by a continuous yellow figure, which sends 
backward on each side behind each orbit a strong process of the same 
color. 
The head resembles that of Graptemys kohnii, but is more slender. 
The symphysis of the lower jaw is longer and the nose projecting. In 
all the skulls examined the jugal is excluded from the orbit, a charac-
