Shape and ^proportions. 



The carapace of the adult is from three-quarters to four-fifths 

 broad as long (actually 71 to 83 per cent.), excessively depressed, 

 either flat or concave in the vertebral region ; depth usually 

 about oae-tifth of the length. In text-fig. 1 {q. v.) the depressed 

 carapace of loveridgii is compared with that of the normal ihera. 

 Marginal region turning downwards and outwards abruptly, 

 excepting the anterior border, which remains flat ; mar-ginals 

 four to eight sometimes perpendicular. Sides straight, either

parallel or oblique ; anterior edge of shell straight or forming 

 a slightly inverted curve, feebly serrated ; posterior border 

 rounded or obtusely pointed, also slightly serrated. Some- 

 times the greatest width is in the pectoral and sometimes 

 in the pelvic region, but in the majority it is equal at and 

 between these two positions. This depends upon the oblique 

 or parallel trend of the sides of the carapace. In the table of 

 measurements the breadth is always taken at mid-carapace.
