1872. j FROM BRITISH COLUMBIA. 873 



described by Dr. Edward Hallowed in his report on the reptiles 

 discovered in the survey for the railroad-route from the Mississippi 

 river to the Pacific Ocean (1859, p. 3, t. 1), which is supposed to 

 be the adult of Aclinemys marmorata, and which most probably is 

 the same as Emys olivacea (previously described and figured in my 

 * Catalogue of Shield Reptiles in the British Museum,' 1855, p. 30, 

 t. xii. c), and Redamia olivacea (Suppl. Cat. Sh. Rep. 1870, p. 36). 



It is very doubtful if the Actinemys marmorata and Emys nigra are 

 the same animal, as the latter is a true water-Terrapin, and Agassiz 

 arranges Actinemys among the more terrestrial Emydioidce. Mr. 

 Lord's specimen is the Chrysemys oregonensis figured by Agassiz (t.iii. 

 f. 1—3) on the same plate as A. marmorata ; but he only gives the fol- 

 lowing very short description. "The back with numerous yellow lines 

 upon a greenish ground, the sternum with irregular blotches in the 

 form of a lyre all over its surface." He figured it from a specimen 

 in the Smithsonian Institution, " which received its specimens from 

 Port Snelling, Minnesota, in the Yellow- Stone River, Nebraska, and 

 among the Guadeloupe Mountains in Texas ;" and he observes that 

 Dr. Holbrook's original specimen, now in the Museum of the 

 Academy of Natural Sciences in Philadelphia, exactly agrees with a 

 living specimen that had been brought from the White-Bear Lake, 

 Minnesota. He has great doubts about the accuracy of the state- 

 ment that this species had been found in Oregon. (Amer. Testud. 

 part ii. p. 4-10.) Lord's specimen was received from further north. 

 It is the young of Emys bellii, Gray, Syn. Rep. p. 31, and 

 Chrysemys bellii, Gray, Cat. Sh. Rep. p. 33, and Emys speciosa, 

 Clifft. Cat. Mus. R. 'Coll. Surg. No. 1525, p. 525. The Emys 

 oregonensis of Harlan and Holbrook, and the Chrysemys oregonensis 

 of Agassiz, appear to be the same species. 



The young Tortoise figured as Chrysemys belli, Ag. t. vi. f. 9, 

 may be a variety, but it has a much smaller mark on the sternum. 



In my later work I am much inclined to regard these Tortoises as 

 local varieties of C. picta, which extends over all parts of North 

 America from the east to the west coast. 



As I am not aware that the young of this Western Tortoise has 

 been previously described in detail, I add the following description. 



Animal blackish olive. The head, crown olive, with a very 

 narrow central yellow line, and a similar line on each side over the 

 eyebrows. The upper jaw, edge with a distinct yellow line, sides of 

 the head and throat with four black-edged streaks, the upper one 

 curved on the side of the nape, the lower one on the side of the 

 throat. The two lower ones on one side united behind ; on the other 

 side they are continued along the side of the neck. The throat with 

 six yellow lines, the two broadest united in front, and forming a line 

 on the middle of the lower beak. The front legs olive, with three 

 continuous white lines in front, extending along the toes to the 

 claws. Outer side of the hinder legs with a yellow marginal band, 

 and a very thin yellow streak on the upper side extending to the 

 toes. Tail elongate, slender, with regular continued yellow lines. 

 Shell broad, oblong, rather depressed, olive-green, the outer margin
