Osteology : — 



b. Adult (shell only). Shields rather smooth ; dark spots 



very distinct. 



c. Half-grown (shell only) . Shields nearly smooth ; sternal 



bands distinct. 



d. Adult (shell only). Shields rather furrowed; sternal 



bands distinct. 



This species chiefly differs from E. ornata in the rings 

 on the shields being more regular, and in the dark spot of 

 the nucleus of the shield being higher up in the costal 

 shields. The sternal bands are generally more or less 

 obUterated in the specimens which have been in confine- 

 ment. 



14. Emys callirostris. The Beautiful Beaked Emys. 

 Tab. XII. 6. 



Shell oblong, very similar in markings to E. ornata and 

 E. venusfa, but the pale rings are narrower, fewer, and in 

 the anterior costal the outer one extends from the upper to 

 the lower outer margin, and the pale rings on the marginal 

 plates are narrower. The head and neck have crowded, 

 narrow, yellow lines, forming symmetrical rings on the 

 throat. Sternum yellow, nearly covered with dark-edged, 

 concentric, irregular bands. Beak with beautiful symme- 

 trical spots, surrounded with concentric black lines. 



Hah. America. 



a. Half-grown (stuffed). America. Presented by the 

 Haslar Hospital. 



15. Emys pulcherrimus. The Dotted Emys. 

 Tab. XXV. fig. 12. 



Shell (very yomig) oblong, broad, rather convex, con- 

 vexly keeled, smooth ; pale brown (when dry), with a round, 

 pale-eyed, dark, subcentral spot, and a curved, dark-edged, 

 pale band below, and a more indistinct one above the spot 



on each of the costal plates. Vertebral shield broad, six- 

 sided . Sternum yellow, with a broad, irregular-edged, black, 

 central, longitudinal band, varied with yellow in front, and 

 vrith a broad black streak on each side near the end of the 

 sternal plates ; margins black-dotted beneath, with a large 

 black ring on the middle of each plate. Head brown above, 

 with three narrow pale streaks, one on the centre, and the 

 others over each orbit ; the upper part of the neck with seven 

 longitudinal streaks, edged with a series of minute black 

 dots ; sides of neck, throat and feet minutely black-dotted, 

 forming tortuous pale lines on the front of the legs. 

 Ilab. Mexico. 



a. Stuffed. Young shields very thin, smooth, nearly trans- 

 parent. Mexico. 



§§ The costal shield with a subcentral, transverse, pale 

 streak, ivith more or less irregular, parallel, dark 

 ohlong rings on each side. Sternum spotted. 



The front dark lines in the first or anterior costal some- 

 times unite, forming spots, which are symmetrical on the 

 two sides of the animal ; the first, second and third ver- 

 tebral shields have an arched pale band, with parallel 

 darker streaks ; and the fourth and fifth vertebral have 

 an arched longitudinal band on each side, with parallel or 

 concentric darker bands on each side of it. These bands 

 are only to be distinctly observed in young well-marked 

 specimens. 



16. Emys HolbrooMi. Holbrook's Emys. 

 Tab. XV. fig. 1 . 



Shell oblong, rather convex, scarcely keeled, longitudi- 

 nally rugose, pale, each shield with two oblong concentric 

 rings, those of the vertebral plates longitudinal, of all the 

 costal transverse ; marginal plates each occupied with two 

 semiovate spots, formed of concentric rings. Sternum 

 yellow, with a large black spot on each shield, and with 

 two large oblong spots of irregular concentric rings along 

 each sterno-costal suture ; nuchal plate elongate ; first ver- 

 tebral square, rather longer than broad, others wide, six- 

 sided. The head, beak, neck and feet yellow-lined ; temple 

 with a large, broad, oblong streak from the back of the 

 orbit along the sides of the neck.
