species are also of the same depressed type \ it does not appear 

 certain that this is correct, in which case the latter specific name 

 should he adopted. 



The specimens here included uuder this head may perhaps be 

 referable to more than a single species; the present- species was 

 founded upon caudal vertebras. 



Hob. North America (Alabama). 



The following specimens are from the Cretaceous of Alabama, and, 

 unless the contrary is stated, were presented in 1859 by Prof J. 

 W. Malet. 



35615. Part of the left dentary, showing eight teeth, of which only 



one is entire. Agrees in relative proportions with the 

 maxilla of L. dyspelor figured by Cope in the Eep. U. S. 

 Geol. Surv. Terrs, vol. ii. pi. xxviii. fig. 1. 



35616. Part of the right dentary, showing one entire and three 



broken teeth, belonging to the same individual. 



35617. The nearly entire right pterygoid of the same individual. 



The teeth are wanting. 



35618. The left surangular and portion of the angular of the same 



individual. 



35619. A small imperfect tooth. 



35620. The extremity of the conjoint premaxillse and fragments of 



the anterior portion of the maxillse of a small individual. 

 The edentulous premaxillary rostrum is well shown. 



35621-3. Fragments of jaws with teeth. 



35624. An imperfect cervical vertebra, 



40984. The centrum of a dorsal vertebra. In its depressed cha- 

 racter this specimen agrees with the dorsals of L. dyspelor 

 figured by Cope, op. cit. pi. xxx. 



Presented by Sir 0. Lyell, Bart., 1868. 



40984 a. An imperfect anterior dorsal vertebra. Same history. 



40984 b. The centrum of a small anterior dorsal vertebra. 



Same history. 



35634. The centrum of a trunk vertebra of similar type. Accords 

 with the specimen belonging to L. dyspelor, figured by 

 Cope, op. cit. pi. xxx. fig. 8.
