33198. The pygal bone of an adult individual. This specimen was 

 not improbably associated with the nuchal No. 30410 g. 

 The sulcus between the last vertebral and the caudal 

 shields was situated on the suprapygal, as in Ocadia ; in 

 Palazochelys bussenensis the middle of this sulcus impinges 

 on to the pygal. Hastings Collection.

 26651 e. The first neural of a large individual. 



26651 f. A right epiplastral. This specimen is remarkable for the 

 extreme width of the gular shield. 



26651 g. A left epiplastral. Agrees in size with the preceding spe- 

 cimen, but has a narrower intergular. 



26651 h. A smaller right epiplastral.

 ceding specimen. 



26651 k. Part of the left hyoplastral and the entire hypoplastral 

 of the same side, in matrix. 



26651 1. The imperfect right hypoplastral.

Humero-pectoral sulcus confined to the hyoplastral; antero- 

 posterior and transverse diameters of entoplastral nearly equal (fig. 

 25) ; hypo- and xiphiplastrals long ; xiphiplastral cornua angulated, 

 and the borders of the intervening notch not emarginate. Femoral
