L865. Maximilian, I'hinz zu Wied. Verzeichniss der Reptilien welcheauf einer Eeise in Nordlichen 

 America beobachtet werden; p. 16, pi. 1, figs. 2 and '■': 



Contains several paragraphs on /•;. terrapin Schoepff, which an- evidently condensations of the 

 inure lengthy descriptions "i' other authorities. Tin- author mentions having seen the animals in the 

 markets of New York and Pittsburg and states that he received in the winter of L832-33, while at 

 New Harmony, Ind., a h.t of nine terrapins from New Orleans which appear to show constant 

 differences from E. terrapin of the mure northern waters, and which he will describe as Emys pileata, 

 "die Emyde mit schwarzen Scheitel." "E. pUeo nigro splendente; corpore cinereo, maculis nigris; 

 testa immaculata aterrima, margine subtus aurantiaco, subrevoluto." Then follows the description 

 of "an apparently female animal:" 



"A thick, rounded emyd, with thick head, massive, strong shell, which, when looked at from 

 above, has a rounded, elliptical form, only slightly com ex; somewhat depressed in front ami behind; 

 seen from the side, is higher in front than behind; all the marginal plates somewhat revolute, and all 

 the vertebral plates with a strong knob or carina, so that the upper line in profile has almost a saw- 

 toothed appearance. The head of the animal is thick, broad, flat above, very smooth skinned, or 

 covered with a smooth, horny shield, which on the top of the head form- a diamond-shaped surface, 

 and is concave, in so much as the sides of the head are somewhat swollen. The eyes are not 

 prominent. * * * The horny covering of the lips is very wide, extending to just below the eyes. 

 The neck is smooth skinned, of medium length * * * Tail rather short. 



"Color: Head and neck ash gray, washed with greenish on the sides of the top of the head. \ "pper 

 side of neck clear olive brown, but everywhere with small black or dark-brown specks. Legs and 

 body darker gray than the head, everywhere strongly .potted: an olive-yellow streak from the eve to 

 behind the nose (often wanting). A constant character is the black-brown rhomboidal field which 

 covers the top of the head, extending from the nose to the back of the head and from eye to eye. 

 Carapace uniform black, sometimes brown-black, but without any markings except the clear orange 

 on the uprolled marginal plates. The plastron is uniform dusky yellow, or clear gray-yellow, with an 

 occasional clouding of brown or dusky, usually uniform, however. Lips reddish vi hire, claws grayish 

 yellow, hind legs and tail dark gray with the dark speckling obscure, iris olive yellow with small gold 



specks. 



"The male similar, but with a black mustache; plastron clouded with brownish black. 



"These emyds occur throughout the Southern States, especially in the salt marshes at the mouth of 

 the Mississippi, near New Orleans, whence they were brought to me alive. They are brought to 

 market by the fishermen, especially the negroes and Indians." 



Maximilian thinks that Dumeril and Bibron bad this species for examination. The plate shows 

 a male with the above characters.

 Sowerby, F. L. S. and Edward Lear. 



A series of plates made under the superintendence of Mr. Thomas Bell to illustrate his Monograph 

 of the Testudinata, but owing to the interruption of that work not published with it. Bell declined 

 to furnish text with these plates and it was supplied by John Edward < bray. 



Emys concentrica, No. 22, p. 8, pis. xxxm, xxxiv, xxxv, and xxxvi. The text is of no value. 

 The description is confined to two lines, and then follow quotations from Agassiz and Holbrook. The 

 distribution is stated to be from Rhode Island to Florida, also along the shores of the Gulf of Mexico. 

 "This seems to he the only Emys common to North and South America, ami it docs not appear to be 

 found in the West India Islands." 



PI. xxxm, a dorsal view of Emys concentrica; » represents a rather large-headed form 



of i; i,l ruin, but with the concentric markings prominent. Female. 

 PL xxxiv represents the under side of the shell only. 

 PL xxxv, dorsal view of E. concentrica; c represents an individual with a much-pitted 



shell. Male. 

 PL xxxvi, dorsal view of E. concentrica; b represents an individual probably a Carolina 

 male.

On page 89 this author gives a diagnosis of the genus Matacoclemmys and describes M. terrapin. 

 The full synonymy is the most valuable part of this reference.
