well elevated and its margin in lateral view is a little uneven; the 

 fourth is distinct and ends abruptly. The first lateral carinae are 

 not parallel, but converge anteriorly. Each is composed of a num- 

 ber of short ridges ending anteriorl}^ in denticles. The foremost 

 ridge is short and terminates in a comparatively large tooth placed 

 a little behind the first of those in the median line. The small 

 teeth or denticles on the two ridges po.sterior to it are also well 

 formed, while the remainder are minute and can only be seen with 

 dilficult5^ At the posterior end of the carapace there are a few 

 additional short ridges, some bearing denticles, between the median 

 and the first lateral carinae. The second lateral carina is also

composed of interrupted ridges, the foremost ending in a stout 

 hepatic tooth situated in advance of the primary median tooth. 

 The ridge flanking the hepatic tooth is comparatively long and is 

 succeeded by another, also of considerable length, which ends in a 

 conspicuous tooth; the remaining ridges, three or four in number, 

 are short and each may or may not bear a small denticle. There 

 are sharp orbital and branchiostegal spines, the latter being the 

 longer and extending beyond the level of the rostral apex. Except 

 for the ridges, the entire carapace is covered with a fine pubescence 

 and also, in many cases, bears several upstanding tufts of long 

 setae.
