ones nearly form a square, the two anterior ones, which are 

 seated on a slight protuberance, being larger and rather nearer 

 to each other than the posterior ones ; the eyes of each lateral 

 pair are placed apart on a tubercle, and are distant from the in- 

 termediate ones. The falccs are short, subconical, very powerful, 

 convex in front, vertical, glossy, and armed with teeth on the 

 inner surface ; the maxillae are short, straight, and greatly en- 

 larged and rounded at the extremity; the lip is semicircular, 

 but pointed at the apex ; and the sternum is heart-shaped, with 

 prominences on the sides, opposite to the legs, and terminates 

 in a point. These parts are of a dark brown colour faintly 

 tinged with red, the extremities of the maxillx and lip and a 

 large spot at the anterior part of the sternum having a yellow- 

 red hue. The legs are short, moderately robust, provided with 

 hairs, and of a dark brown hue tiuged with dull red, particu- 

 larly at the base of the joints ; the fourth pair is the longest, 

 then the first, and the third pair is the shortest; each tarsus is 

 terminated by claws of the usual number and structure. The 

 palpi, which are short, resemble the legs in colour, and have a 

 curved pectinated claw at their extremity. The abdomen is 

 more than twice as broad as it is long, and has a transversely 

 narrow oval form, with somewhat sinuous margins, and six 

 strong, conical, horizontal, rugged, hairy, dark brown spines, 

 two of which are situated at its posterior margin and two at 

 each extremity of the firm, glossy, transversely oval dorsal shield 

 or carapace ; the two anterior spines are the smallest, and the 

 two intermediate ones the largest of the six ; between the two 

 anterior spines there are ten depressions, constituting conspi- 

 cuous red-brown spots, the four intermediate ones, which are 

 the smallest, and nearly equal in size, forming a straight, trans- 

 verse row, somewhat in advance of the rest ; four similar spots 

 in the middle are disposed almost in a square, the two posterior 

 ones being the largest and rather the widest apart ; between the 

 two intermediate spines there are nine red-brown depressed 

 spots; tivc, smaller than the rest, form a straight transverse 

 row somewhat in arrear of the others, the intermediate one being 

 much the smallest; the colour of the carapace is brownish 

 yellow, and there is a spot between the two posterior spines, and 

 a smaller one at the base of each, of the same hue ; the under 

 part is very convex, corrugated, marked with numerous depres- 

 sions, and of a dark brown colour spotted with reddish yellow ; 

 the spinners are encircled by a prominent rim, and are of a 

 dark brown colour ; a bold conical prominence of the same hue 

 occurs immediately before them, and there is a small, obtuse, 

 glossy, yellow protuberance near the base of each branchial 

 operculum.
