FEOM THE TRIAS OF LOMBAEDY. 3- 



the manus being given as 2, 4, 4, 4, 2, which appears wrong a priori, whilst the figure 

 shows 2, 3, 4, 4, 2, which is likewise probably erroneous as regards the outer finger. 

 Curioni, on the other hand, describes and figures the number of phalanges as 2, 3, 4, 5, 3, 

 in both manus and pes. In the face of such contradictions, I think it safest to refer 

 the specimen provisionally to Lariosaurus lalsami, and, contenting myself with 

 describing and figuring the specimen entrusted to me, leave it to those who have access 

 to the typical specimens to decide whether the determination is correct or not. 1 

 beg to thank Dr. H. Woodward, F.R.S., for kindly allowing the specimen to be further 

 developed in the British Museum, and Mr. Barlow for the painstaking and skilful 

 manner in which he has acquitted himself of the task entrusted to him.

of a few anterior teeth, is elongate-acuminate, its length once and two thirds its 

 greatest width at the mandibular articulation. The structure of the palate is better 

 shown than in any of the small Nothosaurians with which we are at present acquainted, 

 yet some of the sutures are not to be traced as distinctly as might be desired. I trust 

 the annexed diagrammatic restoration (fig. 1) will ultimately prove tolerably correct.
