()!<te<il(iii)/ : — Witli onl}'^ a single skull of ('. ilejin-nsu it is not 

 practicable to compare tlie bones in detail as disai'ticulation 

 would be necessary, so tliat only the more striking and 

 tangible cliaractei's are dealt with. 



In general outline the skulls of ('lielonia iinjilns and <'. 

 (lepressa are not strikingly different, but the former is slightly 

 broader and much wider in the supraorbital region. 



Tlie parietal bones of tlie two species differ somewhat. In 

 V. >»//(Z(fs they form a suture of considerable length (an inch or 

 more in adult specimens) with the squamosal. Even in 

 the very young specimen this is quite distinct, but naturally 

 increases in extent with the backward growth of the parietal. 

 In (J. (lepressa however (figs. 47 and 4-8a), the post-frontal 

 extends so far back as almost to enter the hinder border, 

 allowing only a mere splinter of the parietal, about a milli- 

 metre in width, to connect with the squamosal. In ( '. depress^ 

 (fig. 47a) the frouto-parietal suture is tranverse, whereas in 

 the common Green Turtle it is in the form of an arc, the 

 convexity of which is directed forwards.
