CYCLODINA. 235 



tals, sideways to the latero-occipitals, and posteriorly to the occipital 

 shields. The latero-occipitals are the largest cephalic plates, anteriorly 

 contiguous to the fifth and sixth supraoculars, sideways to the upper 

 temporal shield, and behind to the occipital shields. The latter are 

 scale-like, somewhat larger than the scales of the upper region of the 

 neck, and irregular in shape, especially the anterior cross series. Four 

 elongated, temporal shields extend from the orbital ring to about 

 midway towards the auricular aperture. The posterior upper labial, 

 the seventh in the series, is still larger than the temporal shields just 

 alluded to, and under which it partly lies. The remaining upper 

 labials are subquadrangular, subequal, a little deeper than long, and 

 smallest anteriorly. The rostral itself is moderate and subpyramidal. 

 The symphyseal is moderate also, followed on either side by ten lower 

 labials, largest upon the middle of the series ; the anterior one being 

 the smallest, very narrow and elevated. The mental shields are 

 broadly developed : we observe an anterior odd one and three diverg- 

 ing pairs, the first pair alone being contiguous upon the medial line 

 of the chin.
