yellowish dots surrounded with black, and a number of similar spots of 

 yellow and black occupies the posterior end. The upper sides are marked 

 with numerous raised lines, converging towards the terminal upper por- 

 tion of the abdomen. Below there are a number of similar raised lines, 

 separated from the former by a broad whitish band ; they begin at the 

 side of the trachean opercula and converge towards the spinners which 

 are short but prominent, very close together and some distance from 

 the terminal end. Below, the median region is occupied by a similar 

 greyish band as above ; the genital opening is very small, furnished on 

 each side with a minute tubercle ; the trachean opercula are large, sub- 

 quadrangular, brownish, with a transverse slit at the posterior end.

Thomisus Peelianus, Stol Pi. XX, Fig. 4. 



$ The cephalothorax of this species is broadly oval, slightly con- 

 vex, truncate in front, narrower on the sides of the ocular region, and 

 with strongly curved lateral edges ; brown above with the margins 

 all round pale yellowish white, and covered with very short hairs. 



The anterior part of the thorax, where the eyes are situated, is not 

 markedly raised ; the eyes are arranged in two rows, the anterior ones 

 lie on the slope, the posterior above, near the edge. The four middle 

 eyes are small, equal, and form a regular square ; the anterior laterals 

 are sensibly larger than any of the middle ones ; the posterior 

 laterals exceed the size of the latter by a mere trifle, they are direct- 

 ed backwards, forming with the posterior centrals an easy curve, con- 

 vex in front. The falces are short, stout, sub-triangular, broad at the 

 base, on the inner side rapidly sloping towards the end, where a large 

 number of short thick hairs exists ; they are white, the short fangs 

 being, however, pale brown and their joints pale whitish. 



The lip is narrow, longer than broad, subtruncate at the tip ; the 

 maxillce are of about double the length of the lip, also narrow,
